Toothed Whale Research Paper

Toothed Whale Research Paper
Beaked whales, which often have dolphinlike snouts rather than blunt muzzles, typically dive hundreds of meters or more to chase squid, fish, and
other prey. But at least one ancestral species in this group of toothed whales, also known as ziphiids, was cruising near–surface waters for its meals,
new evidence from newly described fossils suggest. Those remains–the first of any toothed whale to also include fossils of its presumed prey,
researchers say–were unearthed along the southwestern coast of Peru last year. The rocks that entombed the partial remains of the whale (Messapicetus
gregarius, depicted in an artist's reconstruction, above) accumulated as sea–floor sediments between 8.9 million and 9.9 million years ago, other fossils

Whales Evolution Research Paper
The earliest whales were land animals with long skulls and carnivorous teeth. Analysis of whale skulls showed major morphological changes, including
changes to the skull size, shape, teeth, and nostrils. Fossil evidence shows that the trait of interest, the nostrils, can be found on fossils of the earliest
whales, dating back to about 50 million years ago. Evolution occurred multiple times since then, each time resulting in the nostrils migrating further
back on the skull. Eventually, the pair of nostrils positioned itself right on top of the head. These nostrils are the blowholes we see positioned on top of
modern whales today. In addition, another momentous change in the nostrils occur when order Cetacea splits into Mysticetes and Odontocetes. Suborder
Mysticetes ... Show more content on Helpwriting.net ...
The first is that early whales had nostrils located at the rostrum, and as they transitioned back into water, evolution occurred and the nostrils migrated to
the top of their head because it was more favorable for underwater life. This allows whales to remain submerged in water while only revealing their
nostrils for gas exchange. Additionally, it can be hypothesized that the Odontocetes gave up one blowhole to develop highly modified tissues designed
for the production and transmission of echolocation and communication sounds. Right whales (Mysticetes) on the other hand, obtain food through
filter feeding, a technique that does not require the same echolocation feature used by dwarf sperm whales for hunting purposes. Therefore, they have
no use for highly modified tissues. Natural selection only selects for traits that are beneficial to the organism, and therefore instead of a trade–off
between a blowhole and modified tissues, right whales "retain both blowholes and use it primarily for air breathing and perhaps olfaction. Having the
two blowholes allow for an increase in airflow, increasing the intake of air in a shorter

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

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

Wind Whale Biomimicy Project
Biomimicry – Wind Whale
The animal that my partner and I chose was the Humpback whale because we want to design a windmill. A windmill converts the energy of wind into
rotational energy by using blades. Windmills are very practical because they reuse wind energy which is pollution fee, they're also much cheaper to
produce and maintain than other energy producers Typically fins are straight and sharp but the Humpbackwhale has tubercles, which is a warty
outgrowth on the bone, on their fins that allow them to become better and agile swimmers. The tubercles are placed on the front edge of the fin. By
creating a windmill that is structured the same way that the fins of the Humpback whale are, the blades will become much more efficient. Frank

Blue Whale Persuasive Speech
The blue whale uses baleen in order to filter the speech. The blue wales are the largest vertebrate animal. In a study that was reported on May 24 in
Proceedings of the Royal Society B, Nicholas Pyenson, the museum's curator of fossil marine mammals, and collaborators Graham Slater at the
University of Chicago and Jeremy Goldbogen at Stanford University, went back and found the evolution of the size of whales in over thirty million
years of history. They discovered that the huge whales showed up along multiple branches in the family tree roughly two to three million years ago. A
reason for whales having those bigger body sizes is that by the increase of ice sheets located in Northern Hemisphere, whales had to change the way
they ontaimed food

Scientific Analysis of Killer Whales Essay
Scientific Analysis of Killer Whales
Scientific Classification:
Order & Genus. The scientific order of all types of whales is Cetacea. This large order is broken down into three further groups as well: the toothed
whales or Odontoceti, which includes killer whales, dolphins, porpoises, beluga whales, and sperm whales, the baleen whales or Mysticeti, which
include blue whales, humpback whales, gray whales, and right whales, and the Archaeoceti order, which are all now extinct. The genus of these species
is Orcinus orca.
Family. The killerwhale is the largest in its family of delphinid. Bottlenose dolphins, common dolphins, and Pacific white–sided dolphins are included
in this group as well. The scientific name for this family is ... Show more content on Helpwriting.net ...
The population can be distinguished because killer whales travel in pods, or groups. The resident pods can vary from as few as five to as many as
fifty whales. The transient pod size varies from one and seven individuals.
Physical Characteristics:
Size. Male killer whales average about twenty–two to twenty–seven feet and usually weigh between 8,000 and 12,000 pounds. The largest male ever
recorded was thirty–two feet and weighed about 21,000 pounds. As a male approaches adulthood, it acquires the typical male characteristics: it gains
weight, and its pectoral flippers, dorsal fin, and flukes grow larger than those of females. Female killer whales average about seventeen to twenty–four
feet and usually weigh between 3,000 and 8,000 pounds. The largest female recorded was twenty–eight feet and weight about 15,000 pounds.
Body Shape. The killer whale has a sleek, streamlined body. Its physical characteristics are adapted for life in an aquatic environment.
Coloration. Killer whales are easily recognized by their distinct coloration. The dorsal surface and pectoral flippers are black, except for the area
below and behind the dorsal fin. The ventral surface, lower jaw, and undersides of the tail flukes are mostly white and the undersides of the tail fluke
are lined with black. A white "eyespot" is located just above and slightly behind each eye and a gray saddle is located behind the dorsal fin. The

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

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

The ungulate hypothesis had morphological evidence based on cerebral blood circulation that indicated a link between Cetaceans and Artiodactyls
(even–toed ungulates).1 It was also hypothesized that another group of extinct mammals, the mesonychids, were the direct ancestors of modern
whales. Mesonychids were a taxa of large and carnivorous ungulates. The evidence that led to this hypothesis was based on the teeth of mesonychids
being similar to the teeth of early whales, called archaeocetes.1 Phylogenetic analyses done in the mid–2000s as well as the discovery of hind limbs in
archaeocetes that lived around the same time as mesonychids, have since shown this hypothesis to be false; mesonychids, however, are considered still
a sister group to the cetaceans.1,2 As mentioned above, phylogenetic analyses revealed that mesonychids were not the direct ancestors of cetaceans.
Similar phylogenetic analyses also revealed that the closest living sister group to the modern cetaceans are the artiodactyls, which include animals like
the giraffe and hippopotamus. More specifically, a sister–group relationship was proposed between Cetacea and Hippopotamidae by analysis of the
cytochrome b gene sequences that included cetacean and Hippopotamus DNA.3 This analysis showed that there was a relationship between the two
groups, but it would be deemed artifactual due to factors such as convergent evolution due to a

Killings in Japan Did you know annually 1,000 or more dolphins are killed by fisherman in Taiji, Japan for meat and monetary needs? Given a set
quota from the Japanese government the fishermen can host their notorious annual dolphin hunt from September until March. With a quota of a little
under 2,000 dolphins', fishermen are allowed to hunt various species that are killed either for meat or sold to marine parks. To help bring attraction to
this horrific dolphin hunt the Oscar–winning film The Cove, was produced with graphic footage of dolphins being slaughtered, shocking people all

Even though they are under international scrutiny fishermen are still able to hunt. The family of the fishermen are still reaping the benefits from either
the dolphin meat or the sales of the day. Japan still using the defense of killing aquatic animals for scientific research. And the environment is still
affected by the loss of thousands of dolphins. But, through all the awareness on Taiji community's dolphin hunting, the dolphins are the ones that suffer
the most. Those that are lucky and get away must fend for themselves without their pod mates, this usually makes them easier for predators to kill them.
The surviving dolphins are forced into the training/export business to supply the demand of swim–with programs and dolphin arias around the world.
Those that are captured for killing, are killed by the slit to their throats, a metal pin into the neck, or metal rods into the spinal cords. These methods are
not up to date to the technique used in slaughterhouses. Slaughterhouses uses a method that kills instantly whereas, Taiji method induces paraplegia
that leads to death by trauma and gradual blood

Information on the Distinctive White Beluga Whale
BELUGA WHALE
1) In 2009, a captive beluga whale rescued a diver during a free–diving competition. 2. Belugas are gregarious and live in social groups of 2–25
individuals (the average group size is ten). 3. Belugas are unique among cetaceans in that the vertebrae in their necks are not fused together. This gives
their heads added manueverability.
2) The beluga whale, or Delphinapterus leucas, is the only member of its genus. It shares the Monodont family with one other species, Monodon
monoceros, otherwise known as the narwhal. They are in the sub–order Odontoceti, which contains 74 species, and the order Cetacea, which contains
89. This in turn is part of the mammalian clade Cetartiodactyla.
3) Beluga whales are born dark gray, but within 8 years their coloration changes to a distinctive white. The species sexually dimorphic, whith males
roughly 25% larger than females. Males weigh between 1,100 and 1,600 kg and are 3.5–5.5 m in length. Females range between 700 and 1,200 kg, and
between 3 and 4.1 m in length. They are Arctic and sub–Arctic, inhabiting the Arctic ocean and its adjacent seas. Belugas are adapted to a range of
habitats including open oceans, shallow coasts, ice flats, and warm–water estuaries. Some populations migrate annually while others remain in an area
year–round. The global population is estimated between 60,000 and 80,000 individuals.
4) Belugas were once thought to live up to 30 years, but this is contested by a recent study that estimated up to 70

Supposedly, in Japan, the whales are killed for their meat for science however they were instead being sold in food markets or even given away
for free to hospitals and schools. This encourages the consumption of whale meat. The Japanese kill many different types of whales for example,
200 minke whales, 100 sei whales, 50 bryde's and 10 sperm whales under scientific research. There is also Norway, which didn't respect the IWC ban
until 1993 as they continued hunting for minke whales. Norway has a fixed number of whalers its whalers are permitted to kill for commercial
reasons. However, this number has rose from 671 in 2002, to more than 1,00 today. Norway are currently hunting a higher amount of female minke
whales in the North Atlantic which could put their long term survival in severe danger. Iceland is another country which has had and still does
whaling. Like Japan, they conducted a 'scientific' whaling programme and later it withdrew from the IWC. Iceland later re–joined in 2004 and they
spoke out in the objection of the whaling moratorium. Iceland targeted minke and fin whales when they continued with commercial whaling in 2006.
However in 2010, whalers from Iceland, also known as icelandic whalers killed 148 endangered fin whales and 60 minke whales. For countries such
as Greenland, they have historically been given an Aboriginal Whaling Quota by the IWC allowing them to

DEVELOPMENT AND COMPOSITION OF MIDDLE EAR STRUCTURES OF BALAENOPTEROIDS (CETACEA, MYSTICETI):
IMPLICATIONS ON FOSSIL CETACEAN PALEOECOLOGY AND BIOLOGY
KERR, Tyler J., University of Wyoming, Laramie, WY, United States, 82071
BACKGROUND
Whales (Cetacea) are unique among mammals in that they possess exceptionally dense, pachyosteosclerotic tympanic bullae1. Along the margin of the
bulla is a highly mineralized, extremely dense wall of bone called the involucrum that serves as a special adaptation to life in the sea and as a means to
facilitate sound reception and directionality underwater2,3,4. Moreover, this cetacean synapomorphy plays an important role in distinguishing its
members from the ancestral terrestrial artiodactyls from which whales diverged5. When cut into cross–sections, the involucral region of the tympanic
bullae in many mysticete (baleen whale) lineages reveals three easily distinguishable 'zones' of concentric laminar growth. Here we hypothesize that
these three distinct zones identified along the length of the tympanic bullae are capable of recording life history events during early development, when
the cetacean tympanoperiotic region is known to be rapidly ossifying6. We propose that the innermost zone (1) represents rapid in utero growth, the
intermediary zone (2) represents rapid birth and postnatal development, and the outermost zone (3), markedly thinner, represents slower, more lamellar
development from weaning on through adulthood.

While the Japanese government justifies these actions by claiming that the research they are performing is ultimately for better management and
conservation of cetaceans, these hunts are unnecessary. Instead of killing whales to perform these tests, there are non lethal research methods that
could be used instead. According to the Japanese Whale Research Program under Special Permit in the Antarctic, also known as JARPA II, the data that
they collect includes the monitoring of whales and krill abundance, the feeding ecology of whales, the effects of contaminants on cetaceans and their
habitat, competition among whale species, and elucidation of temporal and spatial changes in stock structure (2016). Although this research is

The Faroese only perform the yearly hunt, or grindadrap, if all of their conditions are met. In a National Geographic article by Jane Lee in 2014, the
grind only happens if the animals are close to shore, and this has to occur on one of their 23 pre–approved beaches. The weather and waves have to be
calm enough and there have to be enough participants. None of the species that the Faroese target are endangered and they try to cut through the neck
and break the spinal cord so that death occurs quickly. While tribes such as the Faroese adhere to these unspoken rules on ethics, there are Japanese
groups that do not adhere to these ethics and want to take advantage of the subsistence whaling plan. The Japanese largely do not perform the hunts on a
small, aboriginal scale anymore, but have industrialized the whole process and simply wish to be granted higher quotes to hunt more whales. This
brings into focus the ethics of the hunts. In an essay by Paul Watson, cetaceans are extremely intelligent creatures that share much more similarities
with humans than previously thought (2014). Whales have highly developed brains, are able to show a variety of behaviors that can be associated with
certain emotions, can discriminate humans from prey or other sea creatures, and exist in highly developed social circles. They share more similarities
with humans than previously thought and deserved to be treated with this regard in mind. While some aboriginal hunters

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.

The Taagic Story of Dolphin Mistreatment
Ever since I was young, I was always fond of the ocean. The waves that the sea created intriqued me and the animals that lived underwater were
even more unbelievable. I found the dolphin to be extremely fascinating. Since the first time I saw one while surfing at my local beach, Manly, I was
hooked. What I didnt know was the horiffic story behind those playful creatures I saw at aquariums every year. Whether it be on a primary school
excursion or a family outing with my family to the aquarium, those "happy" looking creatures beyond the glass where no more than abused animals
living a nightmare. So where did they come from?
After much research, I found that the countries contributing most to dolphin killing where located in Asian countries in particular Japan. As you can see
in the following chart showing whaling distribution throughout the globe, Japan is a hotpot for dolphin hunts. Because the dolphins can be sold to
marine parks and butchers across the country for such good money, fisherman in the Region of Taiji (an area with large influxes of marine mammals),
kill them annually. Other regions such as Guinea and other Pacific Islands have openly admited that Japan had been financially aiding them to
undertake dolphin kills.
Whats most appauling is the way in which the dolphins are killed. The Tiaji Fishing Cooperative in southeastern Japan have put numerous efforts into
methods that kill the dolphin quickest in the hope that more killings means more profit. The

By over whaling, the increase of whaling, would then decrease in one rapaid movement and also will be causing the water to be polluted. Even though
the whales have been killed centuries ago, it hasn't caused ecological damage due to our un–advanced technologies. Later on, hunting materials start to
evolve between the 17th and 20th centuries where whales today are killed greatly from the increase of globalized commercial whaling.Therefore, it
causes many species of whale not to be recovered from whaling ever since. Furthermore, an Anti–whaling group called Greenpeace have estimated that

Whale meat is back on the menu at about a sixth of Japan's public elementary and junior high schools. Whale meat, because of ocean toxicity and
whales massive size, has high levels toxins. David Kirby, a professional journalist, also says "Whale and dolphin meat is also often loaded with
mercury. In 2011, the EIA purchased whale meat in Japan and found that one sample contains 21 parts per million of toxic metal, 50 times above
Japanese safety limits." So if whale meat is so bad for you, why does Japan still have whale meat on their menus? Japan says that it is an effort to pass
"traditional food culture" down to children. Japan's tradition of whaling has been going on since the 9th century, so it is a long tradition in their country
that they want to keep alive. Not only is eating whale unhealthy, it is also affecting the whale

Killer Whales Research Paper
Ocean giants that have captured the imagination of humans for centuries, whales are among the largest mammals on earth. This diverse group of
animals has over 75 separate species, and are considered by scientists to be some of the most intelligent animals on the planet. While modern whales
spend their entire lives in water, they are air–breathing mammals whose ancestors roamed land millions of years ago. With so many interesting facts
about whales, once question can be easily overlooked: Do whales have (teeth)?
Whales belong to infraorder Cetacea, which includes two other ocean–dwelling mammals: porpoises and dolphins. While all whales are carnivores,
that doesn't mean all whales have (teeth). Scientists divide whales into two different parvorders based on this phenomenon: Odontoceti and Mysticeti.
Whales that belong to parvorder Odontoceti are also called toothed whales. Toothed whales actively hunt their food and are known to eat a wide
variety of animals including sea otters, seals, sharks, squid, and even other whales.

When a baleen whale finds food, it opens its large mouth and sucks in whatever it plans on eating with large amounts of sea water in one of three
ways. Gulp feeders wait until they have a full mouth, then press their tongues against the baleen. The pressure pushes the sea water out, and its food
gets caught in the baleen like a giant strainer. Once all the water is removed, the whale swallows its food whole. Skim feeders use a different approach,
skimming along the surface of the water with their mouths open to catch zooplankton. Bottom feeders plow along the seabed and use their baleen to
filter small invertebrates from the

Cetaceans Stranding
Introduction Cetaceans have an important role in the structure and functioning of ecosystems. For a long time, scientists have been studying their
status, distribution, and seasonal abundance through strandings. NOAA's National Marine Fisheries Services defines a stranding as a marine mammal
found dead on shore, alive on shore but unable to return to the water, or in a foreign habitat and unable to return to its own habitat without assistance
(http://www.ifaw.org/united–states/our–work/animal–rescue/faqs–about–strandings). The reasons why cetaceans strand are still largely unknown. The
stranding of single animals is more likely to occur because the animal is ill, diseased, or injured. Mass strandings involve two or more cetaceans that

Cetaceans use echolocation to make sense of their world and has only recently been of concern due to the ability of dolphins to locate objects and
discriminate objects based on size, shape, and composition (Akamatsu, Nakaqawa, & Hatakeyama, 1995). Any disturbance in the form of sound
pollution could cause these cetaceans to mass strand because they are so dependent on sound as their principal sense (Nowacek et al. 2007). Sound
travels very efficiently underwater and so impacted areas can affect thousands of square kilometers out. Most of the sound pollution in the ocean come
from underwater explosions caused by sonar, seismic testing caused by oil and gas industries, or underwater sea quakes through natural events. The
anthropogenic noises can cause deep–diving populations like beaked whales to be threatened and abandon their habitat and surface rapidly. Exposure to
anthropogenic sounds negatively affect deep–diving cetaceans (Cox et al. 2006). There are a number of hypotheses for the injuries in the cetaceans
that stranded in areas of sonar exercises like decompression sickness and behavioral

the whales were slowly decreasing and this would make trips longer and harder to bring back

Persuasive Essay On Dolphins
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

Persuasive Speech On Whaling
Known for being the main attraction at SeaWorld, whales are often admired by tourists and locals. Some may call whales fish, but they aren't, whales
are considered mammals due to the fact that they breathe air. They're apart of the group called Cetaceans which also includes dolphins and porpoises
and they can be found throughout many oceans. We hardly shed light on commercial whaling because it doesn't seem to affect us as humans; however,
knowing that we could be the solution to this problem may change many views on this horrid topic. Whales have many different species, but the
biggest of them all is the Blue Whale weighing in at about 150 tons and growing up to 110 feet long. "The earliest record of whaling as an
organized business is dated about 875", these aquatic mammals have been hunted for thousands of years now. In the 20th century, they often hunted
whales for their blubber, oil and wax, most of which were important ingredients for many things like soap, lamps and lipstick. A list of endangered
species includes whales such as, Bowhead whales, Gray whales, Blue whales, Humpback whales, Right whales, Sei whales, Beluga whales, Finback
whales, Sperm whales, etc. Not only has whaling, the act of killing whales for their resources, affected the list of endangered species, but so has the
loss of their territory. Certain species like the Beluga have become endangered due to the loss of habitat as mankind has corrupted their territory.
Whaling started off with the crewman on a ship rowing themselves in a separate boat towards the whale. Once they were close enough, they would
throw a harpoon attached to a long rope and impale the whale. The long rope was necessary to tire out the whale as it tried to swim away, dragging it
back and killing it with lances. But times have changed and so has technology, in today's society, the weapons they used before have improved
drastically. The harpoons are mechanically propelled meaning, they explode on impact. Whales that were too fast for the hunters are now subjects to
kill. The International Whaling Commission (IWC), has changed commercial whaling since it was created in the 1940s. If commercial whaling were to
go unchecked, unregulated hunting of whales would've

The Makah Tribal Nation: Whaling In The Nineteenth Century
The Makah tribal reservation, held in Washington's most upper northwest corner, retained tribal power throughout the past into the present. Throughout
the centuries, whales have remained a key aspect of the Makah tribal nation identity through cultural values and practices, compared to the other Coast
Salish nation tribes who valued fishing salmon and growing camas. The Makah in past centuries actively hunted whales, and crafted goods (such as
boxes, blankets, and other items) with whales on them. Due to this, In the late 1900s, the Makah tribal nation sought to restore whaling rights lost
during commercial whaling in the nineteenth century. In the nineteenth century, The Makah tribal nation had the intuition to speak to United State

The Major Cause Of The Extinction Of Sea Cows Summary
In the reading, the author presents 3 theories about the major cause of the extinction of sea cow which is a huge marine mammal lived on the coast
of Siberia. However, finding all the explanations questionable and implausible, the lecturer repudiates them and presents some evidence to the
contrary. At first, the author argues that the main cause of extinction would have been overhunting sea cows by native Siberian people since sea cows
were a favorable supply of food in a harsh environment. Conversely, the lecturer brings up the idea that sea cows were massive creatures with a long
body. Owing to the fact that native Siberian populations were small, they would not have needed to haunt a plethora of sea cows. Few numbers of

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

Yangtze Finless Porpoise
In China, laws have been passed that prohibit electro–fishing and rolling hooks among other gear and China has banned fishing in the lower and

K–selected Species: The Finless Porpoise has one calf at a time that is nursed for 6–15 months at a time, during which the mother teaches the baby how
to survive. They live in small pods or pairs and live up to 25 years. Late Loss Species: They reach sexual maturity at about 6 years old, and would live
long if they were not an endangered species as most died from old age naturally and individuals do not reproduce quickly or numerously.
The Yangtze River Porpoise or the narrow–ridged finless porpoise is a small aquatic mammal that can be found exclusively in the Yangtze River.
It is one of six species of porpoise and belongs to the group Cetacea, which includes all species of whales, dolphins and porpoises that are split two
subgroups, the toothed whale and baleen whale mainly based on the difference between feeding styles.
This porpoise falls under the toothed whale group because it feeds with

Southern Right Whales Population Analysis
The southern right whales' population has been changing and it went through a dramatically decline in the late 19th century. Sail whalers hunted right
whales throughout the southern oceans north of 50 degrees (Richards 2009). Also, the Soviet Union captured more than 3000 southern right whales in
the 19th century (Tormosov 1997). This was changed after they signed an agreement in 1935 for the conservation of this species. Populations for this
species is hard to estimate because despite their enormous size, robust population estimates are very difficult to obtain. The results of this research
showed a positive change and an increase in population of this animal. The old population of the 19th century was around 3000 and the current

Based on this study, researchers can know what is the rate of fertilization and where mortality rate is greatest, also they can use this population to
create a model population to see what is the cause and how they can prevent this. These results are important because it showed the evolution of the
population and it helped to see if minimizing the threats is an effective solution and how these threats are affecting the right whales. Also, it can help
assess the recovery of depleted populations, evaluate conservation threats and also to use whales as indicators of the health of local ecosystems
(Fretwell 2014). Doing this study was complicated because the old population was not clear, and assumptions had to be made, such as the population
size at each class. Therefore, the sample size can affect the end result. Also, assumptions had be made in the future population in regards of the
population in each age class, but it was based from a journal. The population will likely keep increasing if the threats that this animal encounter are
minimized. This study showed how the population progresses and what rate but there could also be improvement in learning why southern right whales
prefer coastal warm waters to breed, also it would be interesting to find more research in how these right whales communicate and transmit

Hunting Whales Research
Countries should be permitted to hunt some species of whales. Hunting whales is a tradition that has been around for hundreds of years. The problem
now is that Japan, Norway and even Iceland are are hunting whales under the pretense of scientific purposes. (The Truth about 'Scientific', 2016) There
should be an exemption that also has regulation in order to protect the whale population. Each nation is setting their own standards of how many they
can hunt, and if the rest of the world is concerned with their practices, then coming to a compromise should be something to visualize for the future.

"Young people don't get jobs with the fisheries, because it's very hard and doesn't pay well." (Phelan, 2013) It is very important to look at the big

reach a compromise with the international law. On the other, they should also accept where popular opinion is headed. Like human sacrifices, not
every cultural activity is going to stay around forever. To please everyone, the compromise should be transitional. Eventually,whaling is going to lose

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

Narwhal Poem
Narwhal
The ocean was still and smooth, like a black mirror reflecting ivory clouds and cyan shadows. In it, a pale blue whale of immense size surfaced and
swam gently, like a dropping tear on a cheek.
All the misery from around the world was drawn to the sea and formed its ripples. The whale swallowed the grief silently, from the northeast to the
southwest, and the world was quiet and peaceful.
Over time, the whale could no longer bear and hold the sorrows inside his body. The pain transformed and twisted into a long, grey tooth; it pierced
through his forehead like a unicorn's horn.
One day, people saw this anguished whale from the shore. They were amazed by a creature they had never seen before. They gazed at his splendid
horn, and a strong greed grew inside of their hearts.
People took boats, wood, and anything that could let them float. They surrounded the whale and trapped him, but the whale was too huge to be carried.
So, they used thick ropes to hitch his head, ... Show more content on Helpwriting.net ...
The ocean was angry. It continued to move restlessly; it swept and devoured numerous lives. Humans, however, were ignorant of the change.
Now, the horn hung in the centre of the city. People took pride in it and cheered, never knowing that it was the pain of the whale.
Time passed by. A sailor was drowning in the fierce ocean from shipwreck. He struggled and tried to stay afloat, but desperation and death were
stronger than him. When he was ready to give, he saw an island a short distance away. With his last ounce of strength, he swam to the island and
pulled himself onto the beach. He lay prone on the sand, and couldn't believe that he was still alive.
When he lifted his head up, the forest soughed in the breeze. The subtle comfort slowed his breath and brought him an inner peace he had never felt
before.
The sailor didn't know that the magnificent whale's body had floated up from the bottom of the sea and transformed, creating the island that was now his

Anthropogenic Waves
Rays of pale sunlight pass through a gradient of cerulean blue. The wide–open space seems almost eerie until a humpback whale gently swimming
sings his song, and the space fills with wonder, that is until there is a disturbance.
Cetaceans evolved to use sound as their way of sensing the environment, navigating, foraging, and selecting mates. Anthropogenic sounds have negative
effects on marine life. Humans produce their own underwater sounds through activities such as aircraft over flights, boats and ships (vessels), tourism,
stationary offshore activities, air gun firing, sonars, explosions, and methods to control movement of marine life (W. Johnson Richardson and Bernd
WГјrsig, 1997). Many studies have discovered vessels to be the main contributor ... Show more content on Helpwriting.net ...
Killer whales utilize calls, clicks, and whistles for navigation and foraging (Juliana Houghton et al., 2015). Availability and quality of prey,
contaminants, and disturbance of anthropogenic noise are major threats to this endangered whale. The killer whales in the Salish Sea were studied as
part of a larger ongoing project to understand vessel noise and its affects in more detail. This study used a new version of digital acoustic tag
technology. These tags contain two hydrophones that record all underwater sounds (I will discuss this more further on). Vessel speed was found to
contribute the most to anthropogenic noise on this killer whale population. This study can help managers regulate the speed restrictions of vessels in
order to help this endangered whale species. Again, we have confirmation that vessels are the primary anthropogenic noise affecting cetacean

Marine Mammal Bycatch Research Papers
Acoustic Pingers on Nets in order to reduce Marine Mammal Bycatch
A topic that is known for its controversy is the use of acoustic pingers on fishing nets in an attempt to reduce marine mammal bycatch. While this
idea seems appealing and has its potential benefits, there are also drawbacks to the use of this kind of device as well. When a device such as the
acoustic pinger is invented, it is important to consider the various types of impacts it will have, especially in terms of marine mammal species
conservation.
The desired goal of installation of acoustic pingers on fishing nets is to notably reduce the amount of marine mammal bycatch in fishing nets. While
this is the immediate effect of the acoustic pingers, potential long–term effects ... Show more content on Helpwriting.net ...
The purpose of these devices is to reduce such bycatch, but with every tool there are pros and cons, positive and negative effects. When an acoustic
pinger is put to use, all of these effects must be considered too when a marine mammal is exposed to the noise emitted by an acoustic pinger: potential
for habituation, the "dinner bell effect", changes in swimming behaviors and respiration rates, potential for change in echolocation behaviors, and the
ideal frequency the pinger must have to create avoidance from fishery nets. Change in behaviors of fish not targeted by the acoustic pingers should still
be taken into account as well upon use of these pingers. In addition, issues can lie within how the acoustic pinger is handled by fishermen: inefficient
usage and the potential for equipment failure, along with varying degrees of willingness to use such a device on fishing trips can greatly impact the
reduction rates of marine mammal bycatch, and even create the risk of further increasing bycatch rates when the goal was to lower them in the first
place. Thus, while acoustic pingers were built with good intentions at conserving marine mammal species in attempt to reduce their rates as bycatch in
fisherman nets, careful consideration must occur when putting one of these devices into actual use, including analysis of impacts from the perspectives
of the target marine mammal species, the non–targeted nearby fish species, and the fishermen running the fishing nets. The conclusion can be drawn
that if acoustic pingers are put into use, they must be completely be put into use as a full and not partial set of pingers on the net, high maintenance
must be kept up with to lower the chance of equipment failure, and the pingers must be specialized for certain marine mammal species in order to
produce optimal results of reduction of marine mammal bycatch. It seems that the

Why Whaling Should Be Banned
Whaling is a practice that has been going on for a long time. Whales have provided many different products over the years. Whale fat broken down
for oil to light lamps. Whale bones were used at one point to make the hoops in skirts for fancy dresses. Whale meat used for well, meat. Many
activists say that whaling is inhumane practice that should be stopped. In fact, commercial whaling is illegal under international law and the only
whaling that is allowed for, is scientific research whaling. So, there is a grey area here that is under some controversy. Japan is in the center of this
controversy, for they are whaling in the name of scientific research, however they have a thriving domestic whale meat market. Is Japanese whaling
'scientific research' or an illegal meat packing business? Japan being an island nation has a long history of maritime industry, so that also includes
small time whaling. Japan started to do this industrial scale whaling operation right after World War 2 ended in 1945. I can see why Japan has been
fighting against the international community on this issue. After World War 2, Japan was devastated and meat or any source of protein was in short
supply. The Japanese people turned to whaling to make up for the shortages of meat. Whales are the biggest animals on the planet thus they have a lot
of meat on them. Whale meat has been entrenched into a staple of their diet and culture. Buying whale meat to the Japanese is like an American buying
a steak.

Argumentative Essay On Whaling
An Exemption For Whaling
For this week's written assignment, I have chosen to address the Norwegian and Japanese positions on permitting whale hunting as a cultural
exemption. As someone who was born in Norway, and has visited several whaling towns, I feel that I have some idea of the importance ofwhaling to
Norwegian cultures and national identity. Although Japan is culturally and geographically a very different place to Norway, I feel that the importance
of whaling to both cultures provides some similarities between the two nations.
1. Do you agree with the Norwegian and Japanese position on permitting the hunting of non–endangered species of whales as a cultural exemption?
I find this particular question a difficult one to answer. Whaling is a notoriously cruel method of hunting – "there is no humane way to kill a whale at
sea. Many die a slow, painful death" (Whale and Dolphin Conservation, n.d.). There is also concern from whale scientists about the effect of the hunting
of whales on whale communities and populations (Whale and Dolphin Conservation, n.d.). It cannot be denied that whaling is an inhumane process,
with serious repercussions for the whale species.
However, I do feel that Norway and Japan should be able to exercise their right to self–determination (as expressed in the UN's Universal Declaration of
Human Rights). Both countries argue that whaling is crucial to several of their local communities. The North Atlantic Marine Mammal Commission
states

Whales are some of the ocean's most fascinating amphibious beings. They possess highly acquired communication skills and are believed to have an
intelligence level equal to, and in some species, surpass that of the human brain. The biological, anthropological, and marine educational communities
have studied the whale in a way that sheds light onto the studies of evolution as well. Yet, there are industries that subject these animals to captivity,
hindering the natural development of these animals. Of all the communities contributing to the protection and study of the whale, there is one tipping

Living conditions for the whale are not up to par for what is required even for the smallest of orca calves. Due to the small living constraints, animals
feel claustrophobic resulting in mental health side effects such as psychological trauma. These living conditions also play a factor in captive whales'
life expectancies. Finally, SeaWorld's public image of the business is to prevent the practice of whaling, creating a scapegoat by claiming they do not
endorse its activities. However, SeaWorld also requires healthy, big whales sustainable for a number of decades. SeaWorld's solution is to have a
continuous supply of reproduction through insemination and inter breeding with other parks outside of their San Antonio, San Diego and Orlando
locations. Since the release of CNN documentary Blackfish, much has been said about the life expectancy statistics informed to the general public by
SeaWorld parks, claiming an average life expectancy for all whales from 20–30 years. According to several studies published in scientific journals,
average mortality rates for captive whales are three times higher than in the wild (Parsons). Based on 14 years of American and Canadian research,
Olesiuk et al. 1990 concludes "females mean life expectancy is 50.2 years with a maximum longevity of about 80–90 years...Males have a mean life
expectancy of 29.2 years and have a maximum longevity of about 50–60
