Dolphins in Captivity
Introduction
Most people are fascinated with dolphins and crave to see them in Sea World, or another aquarium,
and even enjoy seeing them perform in shows. However, most people do not think about the harm
that dolphins go through in order for the public to see them. Dolphins go through an immense
amount of physical and mental harm solely for our entertainment. I never thought about the harm
they go through when I first saw dolphins perform in a show. I, like most people my age, simply
assumed that the aquariums actually cared for the dolphins. However, people that believe this are
naïve. We enjoy the shows so much that we do not want to think ... Show more content on

In captivity, they can only swim around in circles, instead of swimming miles and miles each day, so
they do not get nearly enough exercise. Dolphins often go insane from the huge adjustment to living
in a very small space. In captivity, dolphins are not able to hunt for their food like they are in the
wild, and they are fed fish that are already dead. Dr. Lori Marino explains, "they really enjoy the
opportunity to collaborate with each other and catch prey and travel with their companions" (Dr.
Lori Marino). This stimulation is taken away when dolphins are in captivity. Also, dolphins are
forced to spend most of their time at the surface of the tank because tanks are not nearly as deep as
the ocean. Dolphins "spend more than half their time at the tank's surface"(The Humane Society).
This can cause dolphins to obtain skin problems. Dolphins can also get skin problems from the large
amount of chlorine in the tank because they are not used to it. Living in such a small in captivity
tank can cause dolphins a lot of harm because they are meant to live in the large ocean.
In captivity, most dolphins get split up from their family and are forced to live alone, or with other
dolphins that they do not know. According to the Humane Society, "It is almost impossible to
maintain a family group in captivity" (The Humane Society). Dolphins tend to live in pods when
they are in the wild, and when they are brought into captivity they are split from the rest of the

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

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
a marine 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

Bottlenose Dolphin Research Paper
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 and

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

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

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 it´s 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 it´s breath for
12 minutes.

The Dolphin Is A Breed Of Dolphin
Maui's dolphin is a breed of dolphin that is slowly heading toward extinction, as they are a very
endangered subspecies (1). On the North West coast of the North Island in New Zealand (between
Dargaville and New Plymouth) lays isolated areas, which is where the Maui dolphin can be found,
normally found in groups of approximately 1 to 5 dolphins within about 5 nautical miles of the
shore. (2). Maui's dolphin is the smallest breed of dolphins; they range in size from approximately
1.2–1.7m and weigh roughly around 50kg (3)(4). Majority of the dolphin is coloured a light grey
(back and sides), whilst having a white brush of colour along the sides of its body. They have an
identifiable dorsal fin as it is more rounded compared to most dolphin fins that are sickle–shaped (5)
(6). They feed on small fish such as squid, flatfish, and cod, therefore not making too big an impact
on the food chain. Over the recent years Maui dolphins have declined in numbers from
approximately 150 in 2004, down to 55 Maui's Dolphin observed in 2012 (7)(8). According to "A
risk assessment of threats to Maui's dolphins" the subspecies is in population decline holding a
survival rate of 84% and a population decline rate of 2.8% per year, these statistics were taken
between the years of 2001 and 2011 (9). If threats to the Maui's dolphin remain as they are it has
been indicated that there is a 95.7% chance that the population will decline, therefore leading it to
extinction (10). This can be seen as a

Eugene was so indulged by dolphins that he actually started to ponder that he was a dolphin. Not a

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 ...

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

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 bottlenose
dolphin'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 content on Helpwriting.net ...
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

Dolphin Captivity Should Be Illegal
Why I Think Dolphin Captivity should be Illegal Though it is fun to watch dolphins perform tricks
and swim in the water, most of them don't enjoy it as much as we do. Dolphins aren't happy
swimming in concrete tanks, and they are often treated poorly. First of, the dolphins look like they're
always smiling, but that is just the way their face always looks, so you don't know when they are
happy or sad. Plus, dolphins shouldn't be swimming in small tanks. Dolphins are suffering in
captivity. First of, many people think dolphins are always smiling and that they are just happy
animals. Well, actually that is just the way that their faces are supposed to looks. Unlike humans,
their faces cannot move to communicate their feelings.

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 human hearing. The bottlenose dolphins'
hearings are well over 100Hz, which is even greater than the hearings of the

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

June Medford of the Department of Biology at Colorado State University has been able to modify
plants to do just that ("Sentries in the Garden Shed"). Medford claims that the idea of using plant's

escape from threats, they have integrated systems to detect dangers, June Medford took advantage
of their system and made it so they detect explosives among other things ("Sentries in the Garden
Shed"). When a plant detects a chemical found in explosives or any form of air pollutant being
sought to be detected by humans they will have a loss in color and eventually turn white. In studies
done by Medford, plants have been just as good, if not better than the dogs at detecting odors

The book White Dolphin is all about a young girl named Kara. She ,unfortunately, goes through a
terrible time starting with the disappearance of her mother and believing she is dead, too dealing
with contamination in the local coral. When Kara is walking one day with a guy she was not fond
of, Felix, they came across a white dolphin that was trapped in netting and was struggling to

and stop the destruction of the reefs. Branching off of that, there is a song that represents each

"Give Your Heart a Break" which represents Kara's dad, lastly "I Knew You Were Trouble" which

From the capturing process, to the living and training spaces, to the continuously forced
performances they are required to do daily, these animals face an uncounted for amount of stress.
The capturing process allows men to heard groups of dolphins together and trap them into small
coves with nets and boats, then hand picking the wanted ones and dragging them away to never see
open waters again. Project Orangutan talks about the capturing and the stress it inflicts on these
animals, ".. during the capturing process itself as they get entangled in nets and suffocate, others
may die from stress." Not only do these animals recognize the loss of movement but the death of
their friends around them. If the stress of being taken away from their home wasn't enough, they are
then forced to live in concrete cells with no sound reflection. To us that seems fine but when your
strongest sense is hearing and string enough to detect the difference between a ping pong ball and
golf ball, the constant screaming and splashing of water around you begins to take a toll. Dolphins
use a type of sound detection called echolocation, which can be damaged through time by the living
conditions of dolphinariums. Dolphinproject.com talks about the lessening of sounds and
vocalization of these animals in captivity, "This reduction in vocalizations is due in part to the effect
of the echo caused by the walls of the pools where dolphins are defined." The high noise frequency
surround them for hours a day accompanied by the loss of socialization through their echolocation
causes then even more stress and sadness. This alone can lead to one of these animals dying
involuntarily, or even at their doing. Those who may think dolphins are only animals who will later
forget about the process of being captured or that don't recognize the sounds

The majority of small tooth whales are called dolphins. "Dolphins are mammals of the order
Cetacean and the families Plantanistidae and Delphinidae and include about 50 species" (Internet 1).
Most dolphin species are about 6 feet in length, the males averaging 4 to 8 inches longer than
females. The longest dolphin, the bottle–nose dolphin, can reach over nine–feet in length and weight
up to 440 pounds. The smallest dolphin species is the buffalo which is found in the Amazon River.

A dolphin's normal "cruising speed" is about 23 to 25 mph, and if they are bow riding, they have
been known to get up to 30mph. Because dolphins are mammals (warm blooded) their internal
temperature is between 97.9o to 99of. They normally come to the surface to breathe about every two
minutes. Each breath consists of a short, almost explosive exhalation, followed by a slightly longer
inhalation. Dolphins can hold their breath for up to several minutes and are capable of rapid and
deep dives of more then 1,000 ft. Dolphins once were hunted commercially, for the small quantity
of valuable oil extracted from parts of the head and used to lubricated delicate watch mechanisms.
Since cheaper oils have now been found from other sources, dolphins are no longer hunted for this
reason. Many dolphins, however, become accidentally trapped and drowned in tuna nets. "Between
the years 1959 and 1972 an estimated 4.8 million dolphins died this way"
(www.thedolphinplace.com/facts.html). Because of the pressure from animal rights activists and
United States consumers, both domestic and international tuna canners have refused to accept
shipments from fishing fleets that do not protect dolphins. "The Marine Mammal Protection Act of

the country become stranded in shallow water or beach themselves on shorelines. Are these often
sickened or injured animals simply disoriented, or are they making a conscious decision to leave
their tightly–knit social groups and die on the beaches? In other words, do dolphins commit suicide?
Quite possibly.
From what we know of dolphin intelligence, they certainly have the capability of choosing to die.
According to Lori Marino, a researcher who studies the brains and behaviors of animals, we know
that ... Show more content on Helpwriting.net ...
The sophisticated echolocation system that dolphins use to hunt also serves as a constant form of
communication, transferring personal information at a greater rate than do our sluggish human
voices. A dolphin's limbic system, the part of the brain that controls emotions, is also highly
developed. Marino describes dolphins as hyper emotional; when they are hunted by fisherman,
simple panic can send dolphins into cardiac or neurological shock.
A dolphin's mix of intelligence, strong social bonds, and hyper–emotionality can backfire in the
form of destructive behavior. Dolphins in captivity, even those born into it, are deprived of social
interaction with their own kind, resulting in high levels of stress. Captive dolphins may ram their
heads into the sides of their tank or aggressively lash out at other dolphins.
When a stressed dolphin jumps out of its tank, is it making a decision to ends its life? When a sick
dolphin beaches itself, is it a selfless act made for the good of its social group? It's hard to say. A test
has not yet been developed to show whether dolphins understand the permanence of death or their

Characteristics Of The Spinner Dolphin
The Spinner dolphin is a dolphin that is found in offshore tropical waters around the world. It is
famous for its acrobatic displays in which it spins along its longitudinal axis as it leaps through the
air. That is where the name "Spinner" comes from. It is a family member of the Delphinidae of
toothed whales. There are 4 subspecies of the Spinner dolphin. But, the Gray's Spinner dolphin is
most common.
Spinner dolphins are nocturnal, which means they hunt during the night. They do that so they can
rest on a full stomach during the day. Also, they hunt during the night so they can get out of the
scuba divers way. They communicate by whistles and clicks. Using echolocation (calls out to the
environment) the spinners can scan the darkness, ... Show more content on Helpwriting.net ...
Their head has a very narrow shape, even at the top of the melon. They also have 3 colors on their
body, the skin on the dorsal area has a grey color down to the sides where it has a sharp change in
color to a lighter grey. The lower part of the body is so white it looks pinkish. They measure
between 1.29 and 2.35 meters in length and its weight range is between 23 and 79 kilograms. The
name "Spinner" comes from their above water actions. They can leap into the air and make as many
seven complete spins before diving back into the ocean. The power of the spin comes from the huge
acceleration under the water and the torque of the tail just as the dolphin breaks the surface. Female
spinner dolphins reach sexual maturity about 4–7 years, males about 7–10 years. Calves are nursed
for 1–2 years. They approximately weigh around 130 to 170 lbs. Spinner dolphin inhabits most
tropical waters of the world, and can also occur in sub tropical and warm temperate waters. They are
very energetic in the ocean and out of the ocean. Head slaps acoustical messages that often are
intended to get the attention of other dolphins. Head slaps in some cases are used to indicate to the
pod the direction of travel desired by the slapper.
Dolphins, and all marine mammals, are protected from harassment by federal law; under the Marine
Mammal Protection Act. Harassment means "any act of pursuit or annoyance which has the
potential to disturb the dolphins in the wild by causing disruption of their behavioral patterns of
migration, nursing, breeding, sheltering, or resting and

The Maui Dolphin – an endangered species
Introduction:
1. Area of Focus:
The rapidly increasing world population (1 billion in 1820, 2 billion in 1920 and probably 7 billion
in 2020) is putting enormous pressure on the habitats of many animals, as people use more space for
housing and for the production of food. The Maui Dolphin is one species affected by food
production as carried out by the fishing industry. I decided to do research on the Maui dolphin
because of its uniqueness and rarity. My purpose is to find out more about the endangered status of
the Maui Dolphin, why it has become rare, what problems are involved and what can be done to
improve the situation.

Timeline:
As far as my timeline was concerned, I spent the first day deciding on the topic and getting an
overview of the information available. The main research question was not difficult to choose, as
there is no doubt that the Maui Dolphin is an endangered species.
The next couple of days were spent in reading the information on some of the more relevant sites, as
well as skimming through a book on the topic and looking at some educational videoes. Then I
started to summarize the important facts within the framework of my research questions.
Presentation:
What: The Maui dolphin is the world's rarest and smallest known subspecies of dolphin. It is a
subspecies of the Hector's dolphin and has genetic and skeletal differences which make it distinct
from the rest of the Hector's species. The Maui dolphin has distinctive grey, white and black
markings. The sides and back are light grey, with white "flames" reaching up along the sides of its
body. The underside is whitish, while the face, flippers, dorsal fin and tail are all black. There is a
crescent–shaped black mark between its blowhole and eyes. It has a short snout and is easily
recognized by the round shape of the dorsal fin. Females grow to 1.7 metres long and weigh up to
50 kg. Males are slightly smaller and lighter. They are known to live up to twenty years. The calves
live on their mothers' milk for up to a year although they can learn to eat at about six months. They

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 orientation ... Show more content
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

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.

Animal Assisted Therapy (AAT) is the therapy that involves animals in the process of healing. Many
animals can be used to improve the mental and physical health, the most interesting form of AAT is
dolphin assisted therapy. The goal of dolphin therapy is to improve speech, motor skills, behavior
and sensory activity, ("Dolphin"). In dolphin therapy, children and dolphins interact with touch and
sound, playing and completing tasks that encourage stimulation to the child's specific needs.
Examples of disabilities improved with dolphin therapy are Autism, Down's Syndrome, ADHD,
Chronic Pain, and Depression, ("Dolphin"). Many people are naive to the fact that Dolphin Assisted
Therapy works and believe that it is just swimming with dolphins at a much higher price+5.
Research shows that dolphins have the ability to sense disability in humans and that is why dolphin
therapy is so effective, ("Dolphin"). For example, if a person has a hard time making eye contact,
dolphins are able to sense that, and encourage the child to make eye contact through movement and
sound. Dolphins are also known for being able to break down negative energy in a body, the same
way as kidney stones can be broken down by sonar. The vibrations can penetrate the biomolecular
structures in the body and send energy to boost endorphins and change hormones, ("Dolphin"). One
of the most known facilities is Island Dolphin Care. IDC was found when a boy

want to swim with them and play around. There were so many species that I could name that are
dolphins, but my favorite is Bottlenose Dolphins. Males are considered as bull and females are
considered as cow, weird right. What I like is the babies are considered to name as pup or calf.

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

The correlation of this issue of mercury poisoning and dolphin hunting begins with the Minamata

the problem and the government also attempted to cover it all up from public view by calling the

environment they live in, which also means the ocean contains mercury as well. The Japanese

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; Luís 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;

Why Should We Save the Dolphins? Final Draft

Teacher: Mr. Kris(Smith)
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 movies is the Bottlenose Dolphin.
Fortunately for us, this is one of the few species of dolphins that are not yet endangered. However,

fact extinct. This is a sad situation because we could have and should have prevented this. If we do

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.

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 large species of sharks and killer

Evolution Of Dolphins
"The process of evolution can be very slow, and allows living creatures to develop an anatomy that
is structured for them to thrive" (Dolphin Evolution). Evolution is the gradual development of a
creature, especially from a simple to a more complex organism. Many mammals have evolved from
one animal to another. For instance, dolphins has evolved from land animals to ocean animals. All
of the dolphins belong to the cetacean family, which also include whales, dolphins and porpoises.
Dolphins are now aquatic mammals who are very intelligent and curious. However, what forces
made them evolve? And what did Darwin mean by "survive by the fittest"? Or what principles of
evolution or survival are at work? (Samantha & Paula)

False Killer Dolphins
According to Vancouver Aquarium, the false killer whale was first discovered as a skeleton, not as a
live dolphin. Because its skull looks similar to a killer whale's skull' scientists called it a "false"
killer whale (Pseudorca).
Despite having "whale in its name, the false killer whale is actually a large dolphin like its namesake
"the killer whale". The difference between a "whale" and a "dolphin" is much like the difference
between a "ship" and a "boat". It has more to do with size than science. In fact, false killer whales
are large dolphins. They prefer tropical to temperate waters that are deeper than 3,300 feet (1000m)
and occur in the U.S. in Hawaii, along the entire West Coast, and from the Mid–Atlantic coastal
states south. The species can also be found in all tropical and temperate oceans worldwide.[4] The

area. The blowholes of the dolphins are the nostrils for humans. They use to come up from under

According to the site Dolphin Communication Project, dolphins (2016) produce many signals in
different modes, which can include: vocal signals, non–vocal auditory signals, visual signals and
tactile signals. Dolphins use mostly vocal signs and they produce two kinds of vocal signs: pure
tones and pulsed sounds. Pure tones can take the form of whistles, chirps, screams, and other
continuous sounds. Scientists refer to these as 'frequently modulated sounds', which means that the
pitch of the sound changes with time. Also, scientists have leaned that dolphins are able to
reproduce manmade whistle structures with precise accuracy. Dolphins produce whistles at social
situations, they produce different whistles in different situations, and scientists

They typically eat five percent of their body weight. Most of the time dolphins hunt as a team.
Dolphins mainly eat fish and squid. Some dolphins will eat prawns, crabs, or octopuses. Orcas will
eat seals, turtles, and other dolphins or whales. When eating their food dolphins do not chew, even
though they have 100 teeth. They will shake or rub their food on the ocean floor to break it into
small pieces, from there they will swallow the food.
They are very smart; in fact, they have one of the the most powerful brains in the world. They can
teach, learn, and show feelings and emotion. Dolphins are always learning new tricks. They can also
speak using sounds and whistling. Dolphins have strong memories as well. Dolphins have shown
they are good at problem solving. They are pretty intelligent because they have proven they have
self–awareness. This means they can recognize themselves as an individual and recognize
themselves in a mirror. Some dolphins can use tools. For example, they will cover their snouts with
