Climate Change And The Bottlenose Dolphins

Climate Change and the Bottlenose Dolphins
Our delicate eco–system is struggling to maintain it's complex equilibrium. The precarious state of our oceans are largely attributed to the climate
changes that are on going throughout earth. Along with consistently rising global temperatures come many devastating consequences. Our atmosphere
is not the only aspect of our environment that is heating. Global warming is melting polar ice caps, raising water levels in our oceans, and releasing
carbon that has been trapped in ice for thousands of years. The warmer air temperature is heating the surface waters of the ocean and creating more
frequent and more powerful storms. These warmer surface waters are being pushed under in the ocean conveyor belt and the overall affect is a rise in
overall ocean water temperatures. Climate change has been estimated to effect 88% of cetaceans and endangering nearly 21%. More specifically, each
of these changes have harmful, potentially deadly and lasting effects on Bottlenose Dolphins. Ultimately causing dangerous and toxic conditions
leading to an increase of dolphin strandings and death.
During the 1990s scientist were able to collect 5,000 different salinity profiles. From their findings they were able to estimate a 20 percent increase
in freshwater. Due to this increase there was a rise of fresh water by 8,400 cubic kilometer, which can be compared to the volume of fresh water and
ice that is released in lower latitudes from the Arctic each year.

The Cove Dolphins
Approximately 20,000 dolphins are killed legally every year and thousands more are sold inhumanely in Taiji, Japan. The majority of these dolphins
are sold to marine parks and aquariums around the world. Louie Psihoyos and Ric O'Barry's eye–opening documentary The Cove raises awareness
about the gruesome killings of dolphins in Japan. Ironically Ric O'Barry feels that he initiated this problem, as he was one of the first dolphin trainers
/capturers in the 1960's for the show Flipper. After witnessing the star, "Flipper the Bottlenose–Dolphin" commit suicide in his arms, he became a
marine activist, which led to the production of this documentary to stop the problem he created. Louie and Rick expose the plight of the dolphin, the

The universal image of the dolphin portrays the illusion that dolphins are always happy because they consistently appear to be smiling. This, however,
is nature's greatest deception as it is simply the shape of their mouth. Throughout the film the juxtaposition of the beauty of nature is harshly contrasted
with the ugliness of the underlying secrets of the industry in Japan and around the world. The fishing industry is largest in Japan therefore that is
where this movie was filmed. The captive industry has become a lucrative billion–dollar worldwide trade, with all money made from the exploitation,
imprisonment and lifelong suffering of these living beings. A live dolphin captured for amarine mammal park can be valued up to $200,000. The most
shocking fact is that this is legal. The International Whaling Commission outlawed commercial whaling in 1986, but dolphin hunts remain legal. The
film's impact was largely due to the emotional ties between O'Barry and dolphins. Although the filmmakers are extremely biased, his convincing pleads
for our help are strategically made at the most emotional moments. He believes that bottlenose dolphins are being hunted the most "The fishermen are
searching for bottlenose dolphins like flipper". Luckily this type of dolphin is not yet endangered but this

Abstract
This paper explores the life of bottlenose dolphins. In this paper, we explain that dolphins are intelligent and general information about them. The
research was conducted by analyzing books about bottlenose dolphins and doing online research. From doing this research, I learned the truth behind
the myths of bottlenose dolphins and their anatomy.
Some common dolphin myths are "Ancient Greek and Ancient Roman legends tell of dolphins befriending people, especially children, and even
carrying drowning swimmers to safety. Fishermen have long considered dolphins a sign of fair weather and good luck, and in their ... Show more

These smart and intelligent animals are also sometimes spotted following fishing boats in hopes of dining on leftovers. Bottlenose dolphins track down
their prey through the use of echolocation.
"Bottlenose dolphins travel in groups and communicate with each other with a complex system of squeaks and whistles. Bottlenose dolphins are well
known as the intelligent and charismatic stars of many aquarium shows. Their curved mouths give the appearance of a friendly, permanent smile, and
they can be trained to perform complex tricks."(National Geographic Creative.)
Bottlenose dolphins were once wildly hunted for their meat and oil, but today only limited dolphin fishing occurs. Bottlenose dolphins use echolocation
to track their prey and it bounces off the target and returns to it's dolphin senders, revealing the location, size, and shape of the target.
They can go over 20 miles per hour when they work hard. The body shape of a dolphin helps it swim fast. A dolphin's body is shaped like a tube that
is pointed at both ends which helps them move very fast. They are really fast and they are able to move around faster than any other

What's in a voice? Dolphins do not us voice cues for individual recognition
August 8 2017
Dolphins lacked voice cues which may have led to how they learned to use distinct signature whistles. Dolphins use these distinct signature whistles to
recognize each other. The researchers study was on the bottlenose dolphins in the Sarasota Bay, Florida, USA. They were looking for if dolphins react
to the sounds of signature whistles from other dolphins. If they did, maybe the dolphins do use voice cues. From the study, the results were that the
dolphins didn't respond differentially. The dolphins didn't respond to the speaker by not having as much head turns and to non–signature whistles.
The article lists eight different species of dolphins but the dolphin that was experimented on was ... Show more content on Helpwriting.net ...
The mean of the number of head turns to whistles of related versus whistles of unrelated was 10.8 to 12.1 respectively.
The significance of this research is that it told us that dolphins do not use voice cues as a part of their communication. I would fund this research
because this is another step of learning more about how dolphins use their signature whistles to communicate. One thing that might have been done to
make it better was maybe trying the experiment with different age of dolphins to see if the voice cues are used at a younger age or older. The part of
the study I didn't understand was how the whistles were different on the examples. I could see that over a time period the frequency changes but how
does it sound.
The researchers should look into if male dolphins have a different result listening to whistles from to male or female whistles. Also experiment with
the female dolphins. An idea I have is have offspring dolphins in an experiment if they have more head turns to a male whistle or female

SeaWorld Essay
"Splish! Splash!" The sound of bottlenose dolphins jumping and swimming around their tank excites a family at SeaWorld as they wait to experience
their first encounter with the dolphins. Every year, bottlenose dolphins bring joy to hundreds of people in both captivity and the wild, but what do

Bottlenose dolphins are one of thirty–two species of marine dolphins (World Book 297). Their scientific name is Tursiops Truncatus. Males are usually
longer and heavier than females. Bottlenose dolphins can grow to be thirteen feet long and weigh up to 600 pounds (Bottlenose Dolphins). This makes

If a dolphin catches a large fish, it will smack the fish on the ocean floor or the water's surface to break it into smaller portions (McClintock). After
a dolphin catches its prey, it uses its tongue to swallow the fish and push the water out of its mouth (Dolphin Research Center). Dolphins can eat up
to thirty pounds of fish in one day, so it is helpful that they have three stomach compartments, similar to that of a cow (McClintock) (Lockley 69).
Bottlenose dolphins find fish by using echolocation. This is when a dolphin sends out a beam of short sonar pulses from its melon, or forehead. The
beam reflects off of fish or other objects and echoes back to the lower jaw. The echoes are then sent to the ear bones where they are characterized.
Using echolocation, dolphins are able to locate prey that is buried up to one and a half feet under the sand (Cahill 140–141). Bottlenose dolphins are
excellent swimmers. They can jump up to sixteen feet in the air. Three to seven miles per hour is their normal swimming speed, but they can reach
speeds of eighteen to twenty–two miles per hour. Dolphins also porpoise, which is when a dolphin swims fast enough to repetitively come out of the
water and back under the water in one swift movement. This uses less effort than swimming fast at the ocean's surface. When dolphins swim in deep
open water, they often dive. They dive

a.Communication occurs within the dolphin itself.
i.This includes a range of echolocation clicks in the dolphin sonar system used to identify objects underwater. ii. Studies by the US Navy have proven
that a dolphin's sonar communication is accurate.
1.Dolphins can locate a 3–inch sphere 400 yards away (Wexler, 1994).
b.Communication can also occurs between two or more dolphins.
i.This was measured using the rate of whistling in dolphins.
1.According the University of St. Andrews' study, of 29 different dolphins, whistling rates during non–polarized and socializing movements were
higher than surface travel (Quick & Janik, 2008). ii. Dolphins alert stress levels to other dolphins by altering the pitch of their signature whistle
(Wexler, 1994).
Transition: After learning about a dolphin's sense of communication, we can now build upon this information by examining their unique behavior.
III.A final ability worth noting is the social inclination of dolphin behavior.
a.It has been proven that a lot of their behavior revolves around social activity.
i.Randall Wells and his team observed groups of male dolphin behavior in Sarasota Bay, Florida.
1.The dolphins lifted their heads, which allowed them to toss each other out of the water.
2.This proved that these interactions were defining their social relationships (Rohan, 2003). ii. Another study consisting of 52 dolphins proved that

Bottlenose Dolphins: A Very Brief History Of Dolphins
Dolphins have undergone an interesting history as they evolved from their whale ancestors. Archaeoceti is a parvorder comprising ancient Cetaeca.
Dolphins can swim very fast. Swimming speed and duration are closely tied. High speed swimming can probably last seconds, while low speed
swimming may last for long periods of time. Bottlenose dolphins usually swim at speeds up to about 3 to 7 miles per hour. Dolphins breathe through a
single blowhole on the top of itВґs head. The blowhole is covered by a muscular flap, which provides a watertight seal. Bottlenose dolphins usually
do not need to dive very deep to catch food. On an average, a dive may last up to ten minutes. The longest a bottlenose dolphin can hold itВґs breath for
12 minutes.

Bottlenose Dolphins
Bottlenose dolphins produce a extensive variety sounds that are divided into two categories: pulsed emissions, i.e. echolocation clicks and burst–pulsed
sounds; and non–pulsed signals, i.e. whistles (Caldwell et al., 1990; Janik, 2013) (Figure 1:2).
Clicks are high–frequency and directional sounds that are used to detect, discriminate and recognize objects in the environment, including potential
preys (Caldwell et al., 1990; Janik, 2013). These clicks are used to locate/discriminate an object based on the returning echo, and the system is known
as echolocation or biosonar (Griffin, 1958). Bottlenose dolphins produce high–frequency broadband clicks with dominant frequencies generally higher
than 50–60kHz (Au, 1993).
Burst–pulse sounds are ... Show more content on Helpwriting.net ...
(1990), signature whistles are stereotyped and individually distinctive whistles, recognizable by the frequency modulation pattern of the contour (Janik
et al. 2006), and may be the most commonly whistle type produced by an animal in isolation (Caldwell et al., 1990).
David and Melba Caldwell were the first investigators postulating that signature whistles may represent a unique vocalization, different for each dolphin
. These stereotyped whistles seem to be stable for a long time (Sayigh et al. 1990, 2007; Bruck, 2013; LuГs et al., 2015), suggesting that these signals
may be involved in individual identification (Caldwell & Caldwell, 1965; Tyack 1986; Caldwell et al., 1990; Sayigh et al., 1990; dos Santos et al.,
2005).
In isolation, signature whistles may represent 80% to 100% of whistles' emissions (Caldwell & Caldwell, 1965; Caldwell et al., 1990; Janik & Slater,
1998; Sayigh et al. 2007; Janik et al., 2013).
Signature whistles are probably developed through vocal learning during the first year of a dolphin's life, and may remain stable throughout an
individual's lifetime (Caldwell & Caldwell, 1979; Caldwell et al. 1990; Sayigh et al. 1990; Janik & Sayigh,

Tursiops truncatus (Bottlenose Dolphin)
Body Structure
Bottlenose Dolphins are a very interesting animal. They have a fusiform (Spindle shaped) body that allows them to move quickly in the water.
Because of the Dolphins' shape they have bilateral symmetry. They also have a dorsal fin, flippers, and a fluke. However, Bottlenose Dolphins do not
have ears on the outside of their bodies, hair, or hind limbs. The color of this type of dolphin is usually a light grey color to a black. Their stomach is
white and sometimes has a pink hue. One physical adaptation these dolphins have is a telescoped skull. The skull is like this because it allows them
to breathe more easily while swimming. Bottlenose Dolphins also have blubber that they use as insulation and vascular shunts that allow them to
have cooling for certain types of organs and tissues in their bodies. Finally, Bottlenose Dolphins have sharp teeth that let them grasp onto their prey,
so their tongue can push the prey down the dolphin's throat. Bottlenose Dolphins have a range mass of 260 to 500kg which is 572.69 to 1101.32 in
pounds. The average mass of the Bottlenose Dolphin is 400kg. Their average mass in pounds is 881.06.
Diet ... Show more content on Helpwriting.net ...
One way they get their food is by working together. Another way is by trapping their prey onshore. However, they may trap themselves onshore in
the process. Bottlenose Dolphins can also use echolocation (using sound to locate things) to get food. Instead of using echolocation, some dolphins
use passive listening to get their food. The type of food available to a Bottlenose Dolphin depends on its location. Bottlenose Dolphins eat around 4 to
9 percent of their body weight each day. The predators of Bottlenose Dolphins are largespecies of sharks and killer

The bottlenose dolphin is the most common breed of dolphin. Bottlenose dolphins live in groups known as pods, that typically consist of 10 to 30
dolphins. Living in pods are very beneficial to dolphins in many ways. Sometimes pod members will assist a mother in the raising of her calf. They
are typically found in warm, tropical areas of the world. Bottlenose dolphins can live anywhere from 30 to 50 years. Dolphins are one of the most
intelligent animals in the world. A bottlenosedolphin's diet typically consists of mainly fish. Dolphins usually hunt in groups but can also hunt
independently. They use echolocation to help them while hunting. By making clicking sounds and waiting for return echoes, dolphins are able to
determine how far away the nearest object is, and also the shape of the objects nearby. This is not only useful in hunting, but it also to allows them to
discover when a predator may be nearby. Dolphins communicate using sound. For example, they use squeaking, whistles, and clicking noises to talk to
other dolphins in their pods. They also use movement, such as slapping their tails on the water, as a form of communication. Dolphins are useful to
people in many ways. Their intelligence makes them easy to train. The military has trained dolphins to locate sea mines and enemy ... Show more
Many surfers and swimmers being pursued by sharks have been rescued by a pod of dolphins. Using echolocation, dolphins can make out human
skeletons, lungs, and heartbeats. They are especially fascinated by pregnant women because they are able to detect the baby's heartbeat as well.
Dolphins have been credited with warding off sharks and saving drowning people. They are also known to have killed sharks in the attempt to save
someone. Even if provoked, dolphins never act aggressively towards people, but are ready to defend them in times of

Diverse Mating Strategies Among Different Species
Diverse Mating Strategies Among Different Dolphin Species
There are a variety of different mating strategies among different male dolphins species. "Male mating strategies and forms of competitive interaction
among male cetaceans lead to the development of sexually dimorphic features such as prominent postanal humps, reproductive adaptation such as large
testis size, and retained bodily scarring caused by interactions with conspecifics." (Murphy, 2005) Cetacean have been noted to either have a
polygynous or polygynandrous mating system. (Murphy, 2005) These mating systems have led to a number of different types of competition among
males such as contest competition (where males limit the access of other males to females by aggressive displays or fights) scramble competition
(competition to disperse and find sexually receptive females), endurance–rivalry competition (competition to remain sexually active over a longer
period of time), mate–choice competition (competition in courtship), and sperm competition (competition between the sperm of 2 or more males)."
(Murphy, 2005) Individual males will use these different strategies depending on their dominance in rank, size, age , and number and quality of
reproductive females. (Murphy, 2005) Contest competition and courtship competition have been documented in polygynous species such as bottlenose
dolphin (tursiops truncates), and humpback whales.( Murphy, 2005) "Sexual dimorphism in size, weaponry (teeth and husks), and

Common Bottlenose Dolphin
The Common Bottlenose dolphin is one of many dolphins in our world today. According to marinemammalsceince.org the scientific name for the
common bottlenose dolphin is "Tursiops truncates". Like many other mammals, this dolphin has been classified. According to San Francisco State
University Department of Geography "the kingdom Tursiops truncatus belongs to is Animalia, the phylum to which they are grouped in is Chordata,
and their class is Mammalia. The order in which they belong to is cetacean, the suborder is odontoceti, their family is delphinidae, and the genus is
tursiops." Overtime, everything experiences change, even Tursiops truncates. "The order Cetacean is further divided in two types known as the
Odontoceti, or toothed whales, and the Mysticeti, or baleen whales" (Cadelinia 5). The bottlenose dolphin falls into many categories. According to San
Francisco State University of Department of Geography "the bottlenose dolphin falls into the oceanic family, which is comprised of thirty–four species.
It has been concluded that dolphins, porpoises, and whales evolved from Mesonychilds, a group of land–loving carnivores. They have been estimated
to have lived 60 to 35 million years ago. These mammals eventually explored the seam resulting in the morphological and physiological changes of
their bodies to suit their newly discovered habitat"(Cadelinia 1). When looking at timeline pictures of these mammals, it seems to be that the shape of
their beak has changed overtime

The Research On Marine Mammal Captivity
Introduction: In recent years, animals in captive environments such as zoos and theme parks have grown more controversial. The literature I have
reviewed focuses on a particular group of animals in captivity, cetaceans. Cetaceans include whales, dolphins, and porpoises. The literature includes a
range of themes, from their unique level of intelligence to why they may mentally and physically suffer in captive environments. However, it all
connects to how and why these animals live and behave differently in captive environments than their wild counterparts. I had a unique method to
how I researched the literature. Since marine mammal captivity is a personal interest of mine, I have attended educational conferences on the subject
where I have made friends with many scientists such as Dr. Jeff Ventre and Dr. Lori Marino. Since I know them personally, I used their published
research as a starting point because I was already familiar with it and knew exactly where to find it. From there, I mainly used the "related articles"
feature within the database to read through titles and abstracts to find my other six sources.
Intelligence:
Cetacean intelligence has been studied for many years both in captivity and in the wild. A milestone discovery in cetacean intelligence is
self–awareness. An experiment was conducted with two male captive bottlenose dolphins in New York Aquarium. The dolphins were marked on a part
of their body that was not visible without a mirror. After being

How Effective Is A Bottlenose Dolphin's Echolocation?
Echolocation is widely used by many species which lives in different habitats. The process works when an organism observes acoustic signals, and
attains a sense of the space surrounding from noise or echoes that the organism had detected. Animals use echolocation for specific reasons to
determine the presence of nearby preys or predators. This way the process of catching or escaping from objects is more efficient to most species. Many
marine and land based species use echolocation as a defense against their surroundings. Although some researcher finds echolocation more effective
underwater than on land where mainly light is used. Sound can travel through longer complex frequency with objects than light. Many marine
mammals use echolocation... Show more content on Helpwriting.net ...
In "Field assessment of C–POD performance in detecting echolocation click trains of bottlenose dolphins (tursiops truncates)," demonstrates the
performance of bottlenose dolphin's echolocation detectors in three different areas testing acoustic recording. The echolocation rates presented here
were potentially influenced by variation in both the occurrence of dolphins and their echolocation activity among sites (Robert, Read 2015). Based on
the results, dolphins use the same variation in all three sites used in the experiment. The shorter the distance from the predator to its prey, higher
frequency is used in echolocation of the specie. The detection range of any passive acoustic monitoring units is highly dependent on the environment in
which it is deployed and the behavior of the target species being recorded (Robert, Read 2015). Many other environmental factor such as salinity,
temperature, and water depth affects the sound of echolocation for the dolphins. In bottlenose dolphins, the brain is the one that receives the sound
waves in the form of nerve impulses, which then applies the signal of sound and allows the dolphin to understand what the sound

They have a thick layer of blubber which helps them maintain their body heat and protects them from predators such as killer whales and large sharks.
They have sensitive, smooth skin that flakes off and gets replaced every few hours.
Despite the fact that they live underwater and can hold their breath for up to 7 minutes, dolphins must come to the surface to breathe air. A muscular
flap covers their blowhole while underwater and opens to exhale once they reach the surface. Dolphins can exhale air at 160 km/hr (100 mph). When
they inhale, they can exchange up to 80% of the contents of their lungs. Humans, by comparison, only exchange 17% of the air in their lungs when
they breathe.
Dolphins aren't involuntary breathers like humans. They must consciously swim to the surface to take a breath. This means they can never fully sleep.
One side of their brain must always be active so that they remember to breathe. Although they have little to no sense of smell, bottlenose dolphins have

Imagine you are a dolphin swimming happily in the ocean with the other dolphins. Suddenly, you hear something terrible, and that makes you feel
extremely uncomfortable. You swim towards somewhere "safe" to get away from that terrible sound. However, when you get in, you realize it is a
trap! You have been caught! You might be sent to an aquarium or killed to be made into sushi. This unfortunate fate is not a dream, but it is a sad
reality for hundreds of thousands of innocent dolphins. They are endangered of becoming extinct and their main predators are us, humans. Our society
needs to do something to preserve and protect our precious dolphins. Dolphins should be saved because they are an endangered species, it is cruel to kill
such intelligent animals and they are not even safe to eat.
Dolphins: An Endangered Species There are many kinds of dolphins in the world. The most common one that we see in theme parks, aquariums and

extinct. This is a sad situation because we could have and should have prevented this. If we do not save the dolphins, the path to extinct might be
quicker. Therefore, we must help save the dolphins to ensure their population continues to

Bottlenose has to be a fast swimmer because it's considered them to indicate an exercise for them and it is energy efficient for swimming. If they are
put in a zoo they usually make people happy by doing incredible tricks. Other who is in the ocean they usually use their speed and their flukes to
survive from their predator.
Bottlenose dolphins are just like human; they don't lay eggs, but give birth to live babies. Mother gives birth after 12 months and then they remain
with their mother for four year. They soon later live on there own, but stays in a group. They live about 45 years, which long enough for them to

Using The Group Membership Method Resemble Those Found By...
Results in the present study produced using the group membership method resemble those found by Lusseau et al. (2003) in which the Doubtful Sound
population could be divided into three sub–groups. The composition of groups however is somewhat different. This is in part due to different
individuals being present / alive during their study than in the current study. Where all individuals present in both studies are placed across all three
defined groups in Lusseau et al.'s (2003) study, all but Kringel fall into the same single group in the present study. This suggests that, while the overall
sub–group structure may have been maintained over time, there is a degree of fluidity among members of sub–groups. This is the very nature of a
fission–fusion society, where group composition is dynamic over time (Grellier et al. 2003). The three sub–groups may be an apparently permanent
feature of the population when using the group membership method, with the fission–fusion nature of bottlenose dolphins defining the composition of
each group through time. It must be noted however that Lusseau et al.'s (2003) study was over a period of seven years, where 546 days were spent on
the water. Due to the immense differences in field effort, direct comparisons are made with caution. Previous pilot work, which spanned only 6 days,
also yielded similar results using the group membership method.

Zealand
Worldwide inter–specific behavioural interactions in the order Cetacea are diverse and often complex. Epimelatic care can be described as nurturant or
Succorant in nature. Adoption can be classified as nuturant behaviour, however very few examples of nuturant adoption have been reported among
wild cetaceans and even less between species. During routine dedicated transect surveys, an adult female bottlenose dolphin (Tursiops truncatus) was
found in the presence of a young common dolphin calf that did not appear to be her own. This mother–calf–like relationship lasted 9 months until the
mother was sighted on multiple occasions without the calf. This paper describes repeated behavioural observations of apparent inter–specific
association, and discusses the "type" and potential function of this interaction.

Essay on Bottlenose Dolphins
Bottlenose Dolphins This essay is NOT formatted Bottlenose dolphins are among the most vocal of the nonhuman animals and exhibit remarkable
development of the sound production and auditory mechanisms. This can be seen in audition, which is shown in the animal's highly refined
echolocation ability, and in tightly organized schools in which they live that are made up by sound communication. In testing the communication skills
of dolphins, extensive studies have been done on vocal mimicry, in which the animal imitates computer–generated sounds in order to test motor control
in terms of cognitive ability. Language comprehension on the other hand has been tested through labeling of objects, which has proven to be... Show
1986). In order to understand the complexity of these highly mechanized acoustic systems, it is necessary to learn the process for which the dolphin
hears. In most water–adapted cetaceans, tissue conduction is the primary route of sound conduction to the middle ear. The isolation of the bullae
shows an adaptation for tissue conducted sound. The lower jaw contains fat that is closely associated with the impedance of seawater. The lower
jawbone of most odontocetes becomes broadened and quite thin posteriorly, and the fat forms an oval shape that closely corresponds to the area of
minimum thickness of the jaw. This fat body leads directly to the bulla, producing a sound path to the ear structures located deep within the head.
Paired and single air sacs are scattered throughout the skull, which serve to channel these tissue–conducted sounds (Popov & Supin, 1991). Other than
this description, there are still more studies needed to determine the function of the middle ear and the type of bone conduction that occurs within the
bulla. Due to detailed audiograms, dolphins have been shown to have the ability to detect high–frequency sounds. In an experiment by Johnson (1966)
as cited in Schusterman et al. (1986), sine–wave sounds ranging in frequency from 75 Hz to 150 Hz were presented to a bottle–nosed dolphin. The
animal was trained to swim in a stationary area within a stall and to

A Research Study On Bottlenose Dolphins
Bottlenose dolphins are among the most familiar cetaceans, just as whales. The Bottlenose dolphin is a primitive member of the subfamily
Delphinine. Bottlenose dolphins are grey, varying from dark grey at the top near the dorsal fin to very light grey and almost white at the underside.
There are two ecotypes of bottlenose dolphins the coastal and the offshore. The Coastal dolphin has a small body and large flippers to increase agility
and heat dissipation. They have a limited movement into offshore waters and like shallow warm water near the shore. Coastal dolphins for the most
part remain in their region. The Offshore dolphin has a large body to help conserve heat and defend itself against predators. They are less restricted in
range and movement and like deep, cold waters. Offshore dolphins in the North Atlantic have migratory patterns that follow prey distribution.
Bottlenose dolphins live in groups typically of 10–30 members, called pods, but group size varies from single individuals up to more than 1,000. In a
case study performed by Randall Wells who is the leader of the longest study of dolphin population since 1970, it was discovered that there are three
main factors that influence migration: Seasonal changes in prey location, predation pressure and reproductive requirements. (Wells, 1980). In the fall
dolphins follow mullet fish when they migrate from the bays into the Gulf of Mexico to spawn. Dolphins experience the most predation pressure
during the summer when

The Importance Of Animal Behaviors
Animals are more humanlike than you think! Animals have many humanlike emotions and behaviors, but this can scare people or "blind" them.
When it should boost conservation attitudes. Animals actually have all the emotions as humans do, they just don't always show them in the same
ways humans normally do. Animals have all the primary and learned emotions but do not always express them in the same way as humans do.
Animals experience pain, but that does not mean they all show it in the same way. For example, a fish will express grief/sadness by hiding or by
swimming back and forth really fast, and they will act really strange. Some chimpanzees, to grief, will stay around the body of a dead friend for long
periods of time almost protecting it ("Animal Behaviors"). This data is relevant because we now know what emotions most animals do and do not
have. Animals can also have many behaviors that humans have too. For example, chimpanzees use tools to help them with everyday tasks. An
example is chimpanzees use sticks to poke potential predators to see how much of a danger they are to them. Chimpanzees also use rocks to break
nuts to eat (Animal Behaviors). This is data is relevant to the claim because it shows us what kind of human–like behaviors animals have. Humans have
primary emotions and multiple learned emotions. Primary emotions are emotions that are expressed by all cultures and they are anger, sadness,
happiness, surprise, disgust, and fear. Learned emotions are

Vaquita Research Paper
When you hear the name vaquita, you probably think about the word "cow" or "small cow" in Spanish, but the truth is there is an animal out
there named that in English, and their numbers have been dropping treacherously low. Also known as the Gulf of California Harbor Porpoise, or
by it's Latin name, Phocoena sinus, as well as cochito or desert porpoise, this cetaceans resembles a dolphin, having the same sleek, grey dorsal
surface, it's only distinguishable feature being it's flat or rounded face and dark areas around the eyes and mouth, making it look like it has a short
beak. Newborn offspring have a much darker coloration. Vaquitas are relatively small in size, adults being 5 feet long, which is about the high of the
average teenager in the United States, while offspring are about the size of a large human baby or a small toddler. An adult vaquita weights up to 120
pounds.... Show more content on Helpwriting.net ...
Since not very much is known about vaquita's reproductive behaviors, it is believed that vaquitas become sexually mature as early as 3 years of age,
but most commonly at 6. Females give birth to one calf approximately every two years. Mothers nurse their offspring for 6 to 8 months, and then left
when they are strong enough. Vaquitas are carnivorous, feeding on different types of lagoon fish and other marine animals. They use echolocation to
track down their dinner, which includes species from demersal (flatfish, manta rays and flounders) and benthic (crustaceans) zones, teleosts (croakers,
sea trout and grunts) as well as squid and other smaller fish. Vaquitas are native to the northern Gulf of California, staying around the gulf's shallow
areas, though swimming away when a boat approaches. They are the only porpoise found in such warm temperatures

The Bottlenose Dolphin Essay
Have you ever wondered how the Tursiops Truncatus dolphin got its name? It got its name because it's nose, which is short and stubby. The Tursiops
Truncatus' coloring is different from other dolphins. Their physical appearance is intriguing and distinctive. They have fascinating family life and
eating habits. You can even see bottlenose dolphins in many places in the U.S.A. Their main home is the Pacific Ocean, but they also live in many
other places. The coloring of the bottlenose dolphin is unique. It is light gray on top and pale pink on bottom. This coloring helps disguise itself from
its predators. The light gray coloring helps it be camouflaged with shadows in the water. The underside coloring, a pale pink, helps the... Show more
Hydrodynamic motion is impressive water movement or quickly moving water. The bottlenose dolphin's head allows for twenty to twenty–four sharp,
conical teeth on each side of the upper jaw, and eighteen to twenty–four teeth on each side of the lower jaw. That gives the bottlenose dolphin
seventy–six to ninety–eight teeth in all! Conical means cone–shaped. These teeth might compare to the human incisors. The teeth are used mainly for
catching food and holding the food so it won't get away. The eating habits of the dolphin can vary by habitat, location and the food accessibility and
availability. Bottlenose dolphins may eat many various aquatic organisms. Usually bottlenose dolphins eat fish and crustaceans. They also may eat
octopus, mackerel, cod, herring, mullet, squid and eels, along with shrimp. The adult dolphins take in about four to five percent of their body weight
in food each day! The average bottlenose dolphin will consume seven to ten pounds of food a day. Of course, the male will eat more than the female.
A nursing mother will eat more than the standard dolphins; she takes in about eight percent of her body weight. When hunting for food dolphins may
corner the prey in shallow water. The bottlenose dolphin will usually swallow the prey's head first. For larger fish, such as the impressive hammerhead
shark, several bottlenose dolphins will kick it out of the water with their flukes. This injures and stuns the large fish and the

Internal characteristics As a member of the Mammalian class, bottlenose dolphins are warm–blooded, or endotherms (Cavendish, 2002).
Normal habitat, including geographical location The normal habitat for bottlenose dolphins are the temperate and tropical waters situated between the
Gulf of Capricorn and the Gulf of Cancer worldwide (Bottlenose dolphins habitat, 2013) except for the northern Pacific and polar seas (Cavendish,
2002). Although their habitat is worldwide, the distribution of the bottlenose dolphins is typically restricted to surface water temperatures of 10В° to
32В°C (50В°–90В° F) (Bottlenose dolphins habitat, 2013).

Drive Hunting in the Oceans
Every year tens of thousands of marine mammals are killed all over the world, with over twenty thousand small cetaceans killed in Japanese waters
alone (Butterworth et al., 2013). These small cetaceans include various species of small whales, many dolphin species and some porpoises. They are
killed in various manors, ranging from accidental ship strikes to the more morally controversial yearly drive hunts. As you may know nearly all
cetaceans use some sort of sound production in order to navigate waters, communicate with other individuals and groups of their respective species as
well as capture prey (Brownell et al., 2008). An example of this is the variety sounds produced by bottlenose dolphins (Tursiops truncatus) when
exploring and foraging. These types of noises vary from echolocation, whistles and pops according to Nowacek (2005) which aid in location of prey,
and communication when hunting in groups. Bottlenose dolphins are one of the most well–known cetacean species (Bearzi et al., 2008). They inhabit
various marine habitats across the world including just about any region with a warm–temperate to tropical ocean climate (Reeves et al., 2002). Just
like many other cetaceans they are well known for inhabiting coastal areas, which makes them particularly vulnerable to human interaction and threats
they wouldn't necessarily face on the coast of uninhabited lands (Wilson et al., 2008). This use of sound is an extraordinary adaption for life under the
sea, unless of

Dolphin Foraging Techniques Essay examples
Bottlenose dolphins are known to use sea sponges as tools when foraging for food in the ocean. This behavior is referred to as "sponging".
"Sponging" refers to when these particular dolphins put a sea sponge over their rostrum (snout area) and use it to help collect food. Different
explanations have been given as to why Bottlenose Dolphins engage in this behavior. It has been perceived that young dolphins learn this behavior
from their mothers. Researchers are also exploring the option that a differentiation in diving skills exists between dolphins caused by variation in the
mitochondrial genes processing of proteins that are involved in the creation of the Bottlenose Dolphins' respiratory system, and that variation may have
lead them to... Show more content on Helpwriting.net ...
Once found, researchers documented the behavior of these groups and the activities that these groups partook in. Long–term photographic databases
were used to establish identity, and if the dolphin was noticed to be engaged in sponging at least once, they were included in the dataset for the study.
On the eastern gulf, researchers were already aware of the sponging dolphins due to previous studies.Between the years of 1994 and 2008, remote
biopsy samples of sponging dolphins were taken when the opportunity to do so allowed. Using a Magellan Meridian Marine GPS device, the site that
each biopsy was taken at was noted appropriately. The biopsy sample was made up of 29 sponging dolphins and 54 "non–sponging" dolphins. At a
total of 83 dolphins, 59 of the dataset consisted of 24 males and 59 females. The researchers recognize that sponging is a predominantly female
activity, however they observed some males engaging in the activity as well and for that reason they decided to include males in the data, as to test for
possible gender influences, but genetic influence is what they researchers were truly looking to rule out. To do this they chose to examine the coxII
and ctyb genes, using a Gentra Tissue kit to obtain the DNA. These two mitochondrial genes play a vital role in the respiratory chain, which is link
directly to the dolphins' metabolic energy and therefore could possibly affect the overall diving ability

How Does Anthropogenic Noise Affect Cetaceans
Introduction As human presence in the oceans is continually revealed to be detrimental to marine life, one major area of concern is noise pollution in
the ocean and its effects on marine mammals. Sound is vital to marine mammals' communication and livelihood, so the disturbance of the sound in
their habitat has varying effects. The impact of anthropogenic noise on marine mammals, specifically cetaceans, can be seen in various experiments and
observations concerning the sounds produced by shipping, construction, and sonars. All of which reveal potential and consequential behavioral and
physiological effects, which include acoustic masking, change in foraging behavior, and mass strandings. Species studied include harbor porpoises
(Phocoena phocoena),... Show more content on Helpwriting.net ...
It is important that we continue to research known harmful anthropogenic sounds and their effects on cetaceans to limit further damage, and to
research other sources of noise due to humans and their potential effects to prevent future harm. Through research, it is shown that various noise
pollution caused by humans can have detrimental effects on cetaceans such as harbor porpoises, bottlenose dolphins, killer whales, and Cuvier's beaked
whales. Shipping, windfarm construction, and sonar can cause temporary or permanent hearing threshold changes, which can result in decreased
foraging ability and communication ability. Shipping has been seen to decrease foraging time and cause acoustic masking. Sonar can cause death due
to strandings and lesions. These all add up to show that, overall, noise pollution by humans has a serious effect on the quality of life for cetaceans. It is
also important to recognize that absence of a detected reaction does not mean that there is no impact on these cetaceans. It is possible that noise
pollution can cause physiological and psychological responses without any external symptoms we can detect. It may be important to develop methods
to observe these more subtle reactions to noise pollution that may impact cetacean's way of life. It is important that humans realize the full extent of
their effect on marine life and create measures to prevent more harm. Noise pollution's effect on cetaceans affect not only these species, but the other
marine life they interact with and the ecosystems of the

Review Of The Article 'Dolphin Eats An Octopus Without Dying'
"How a dolphin eats an octopus without dying" Sarah Zielinski recently did an article in April on how can dolphins eat octopuses.She explains that
dolphins and humans share a similarity, that as good as an octopus may taste it is difficult to eat mainly because of their tentacles. Unlike humans
dolphins do not have the same resources we do that allow eating an octopus to be easy. Zielinski speaks on how it is possible for dolphins to enjoy
the meal without hands and or suffocating. In Zielinski's article she provides facts and necessary information to prove that dolphins can eat octopuses.
The article is filled with facts. She also throws in some photos as proof to show how the dolphins do what they do to eat the octopus. There is more than

The bottlenose dolphin, genus Tursiops, is a cetacean renowned for its social intelligence, even being prescribed the status of non–human persons along
with other intelligent species such as great apes. Both dolphins and primates share a number of attributes that have led to an evolutionary propensity
for intelligence, including prolonged parental care, long lives, complex social bonds, and communicative cooperation (Reynolds et al., 2000). But
unlike primates, dolphins lack opposable thumbs, as well as any sort of limb that is able to manipulate their environment capably. Dolphins evolved in
an environment that is less affected by gravity and provides three–dimensional movement, but provides limited chemosensory and visual cues for

Dolphins are able to plan their behavior to achieve a solution more efficiently, as well as create novel behaviors. Trained to move weights across a
pool to receive a reward, each dolphin independently deduced that they could carry multiple weights at once to reduce the number of trips (Kuczaj et
al., 2009). In another test they were able to plan the order of dropping weights in order to optimize the number of fish rewards they could receive
(Kuczaj et al., 2009). These demonstrated their ability to analyze problems, plan an appropriate solution, and carry it out in an efficient order. Mirror
self–recognition (MSR) has also been demonstrated in bottlenose dolphins, with the dolphins using the mirror to investigate a mark on their heads
using a mirror, a level of self–awareness only shared by great apes (Marino, 2002). It is possible that the level of cortical connectivity is a significant
factor in the emergence of complex cognitive capabilities such as self–recognition (Marino,

The Interesting Dolphin
Many people know those cute, funny, intelligent animals that are known as dolphins, right?
There are so many interesting things about them. Dolphins have been around for about 15 million years now. They're extremely intelligent, probably
even more intelligent than us humans. Dolphins are becoming endangered because of humans and many don't know that. They are known as the
oceans most kind animals.Dolphins have originated millions of years ago,are extremely endangered,and are becoming endangered.The most important
thing to know about dolphins would probably be how they originated because without that those cute aquatic mammals wouldn't even exist. Dolphins
have been around a lot longer than humans. They originated about 50 million years ago. The most common dolphin, being the bottlenose dolphin, has
been around for 15 million years. Surprisingly, dolphins originated from members of the cetaceans group. Cetaceans used to be land mammals but
evolved into being aquatic mammals. In From Land to Water it stated, "The transition from land to water is documented by a series of intermediate
fossils from India and Pakistan." This research helps prove how they used to be land mammals but evolved to live in the ocean. Dolphins are one out
of many aquatic mammals who need oxygen, but they need water in order to live. Believe it or not, dolphins are somewhat related to hippos, camels,
deer, cattle, and giraffes. In From Land to Water, " Many features that are

Bottlenose dolphins are said to be the smartest animals in the world next to humans. They are very intelligent and show it in many different ways.
Dolphins are very social animals that love having attention. They will do a lot to get it. Many dolphins smarts are used in shows. They learn easily

they weren't so smart. Bottlenose Dolphins are some of the most loved and admired animals in the world.
A dolphin's behavior is not only based off of one thing, it's based off of many things. Their behavior is affected by their surroundings, companions,
mood, and many other things. In order to survive, dolphins must protect themselves from predators and also must eat. This involves a lot of everyday
activity. Dolphins also need to breathe. If a dolphin doesn't come up for air, it ... Show more content on Helpwriting.net ...
While they are traveling, the dolphins often ride on bow waves or stern waves. They learned this from riding ocean swells, which they learn
naturally. A bottlenose dolphin can jump up to 16 ft above the water level. When they land, it is on either their back, belly or side. This action is
called a breach. Dolphins will breach for show just to get attention. To protect pods from danger, larger adult males will swim around the group and
watch for predators. Their actions are like scouting for the pod. If one dolphin is sick or hurt, two others will assist it to the surface so it can breathe
(Entertainment). Unlike humans, dolphins are voluntary breathers. One part of their brain must always be active in order to survive. The dolphin
needs to remember to swim to the surface every so often to breathe. A dolphin can hold it's breath for up to seven minutes. When they inhale, they're
exchanging eighty percent of the contents in their lungs (Animal Fact

Introduction
About seventy million years ago, the terrestrial ancestors of dolphins and whales re–entered the marine environment where life originally started. This
had a profound effect on their locomotion, diet social behavior and reproduction; for example the breathing system in the waters rendered useless the
olfaction of the cetaceans. In water, both animals were met with vision challenge, since light doesn't travel very well in water; they had to adapt. They
started to communicate through low frequency sounds. Dolphins have evolved echolocation similar to sonars and bio sonar communication method
used by bats. Large baleen whales also evolved low frequency calls suited for long distance communication: they produce and hear the low–frequency

Dolphins are smart animals that could recognize themselves when looking at the mirror, whereas other species would think that they are looking at
another animal that had the same looking with them. Dolphins also have the ability of understanding the language the scientists made to teach them.
Scientists mostly use two main make up language to teach them. One of them is to use whistle sound to tell the dolphins to do some actions or pick an
objects. Another is giving simple questions to the dolphins and to let them answer whether "Yes" or "No". The dolphins had an average of
seventy–five percent correct responses to the question. Dolphins use a feature called echolocation to create acoustical pictures of their surroundings.
Although it's very hard to see any evidence of an external ear opening, they still have a strong hearing. They confused the scientists by having a small
ear opening, but a great sense of hearing. The inner ear of the bottlenose dolphins is adapted for hearing ultrasonic frequencies far beyond the range of

Sperm Whales Analysis
Sperm whales use "rapid pulse trains and creaks when they dive to great depths" (Jones 2005). The creaks, as mentioned by Jones (2005), are
"associated with rapid body movements [by the whale] suggestive of pursuit of prey" (Jones 2005). These whales utilize the rapid pulses when
closing in on their prey to hone in on the finer details, almost identical to the terminal phase of bats. Dolphins can produce a variety of different
sounds for different purposes. Each individual sounds different, and even produces it own variety of clicks or noises. For example, bottlenose
dolphins use certain tones of whistles to communicate 'pleasantries' to one another. They also can produces barks or wailing that is considered a series
of longer duration clicks
