Cetacea Essays

Cetacea are one of the most unique orders of mammals. They include the largest marine animal that has ever lived which is the blue whale, the intelligent dolphins, the tusked narwhals and the singing humpback whales – almost eighty living species in all. Even though a lot of hunting has been done to the family of Cetacea, observations has been dictated that its number are slowly increasing. The oldest fossil whales are grouped together just for the convenience of others. Archaeocetes are the oldest

Dolphins are mammals, breath air, give birth and nurse their young ones. The ancestors of dolphins were animals that once lived on land but turned to the sea about 50 million years ago and never returned to land hence the dolphin’s ancestor had to slowly adapt to its new environment. Its front legs became flippers and its tail became flukes that it uses for swimming and steering respectively. The same bone structure is shared by bats, flying mammals in the order Chiroptera. While the trait for them

Whale is the common name for a widely distributed and diverse group of fully aquatic marine mammals. They are an informal grouping within the infraorder Cetacea, excluding dolphins and porpoises, so to zoologists the grouping is paraphyletic. The whales comprise the extant families Cetotheriidae (whose only living member is the pygmy right whale), Balaenopteridae (the rorquals), Balaenidae (right whales), Eschrichtiidae (the gray whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm

KILLER WHALE & BOTTLENOSE DOLPHIN BY NOAH HEBERT 1. Noah Hebert Research paper project February 10th, 2018 My first animal i would be talking about is the killer whale. More specifically the kingdom this animal comes from is the cetacea which is a diverse set of aquatic creatures such as porpoises, dolphins, and whales. Generally cetaceans are spread out worldwide but it’s shown that most of the species enjoy living in colder waters in both the southern and northern hemispheres.

The interactions between humans and dolphins started centuries ago when our ancestors carved drawings of cetaceans on rocks and passed on legends and folk tales; some described them as beasts and others as spiritual creatures. These marine mammals are also hunted as long as three thousand years ago as resources: their meat for food; their blubber for oil, and their teeth and bones for clothes, jewelry, or tools (Bauer, McCafferty, Simmonds, & Wright, 2013, p.201). As time pass, dolphin and whale

California sea lion (Zalophus Californianus) - Key characteristics – interactions with humans – communications – Feeding habits – reproduction – threats - conservation Introduction: California Sea Lion, Zalophus Californians belongs to the family “Otariidae”. The animal is found along the coast of the eastern North Pacific. The breeding of California sea lions takes place on islands off the coasts of California and Baja California. They inhabit rocky and sandy beaches of coastal islands and mainland

History of commercial fishing in Hawaii Shortly after Statehood, a U.S. De­partment of Interior, Bureau of Com­mercial Fisheries proposal labeled the Hawaii fishery as "dying". Hawaii's major commercial fisheries had been dominated by traditional prac­tices that reflected Hawaii's Japanese immigrant heritage and its impact on the local fishery and seafood markets. The predominant commercial fishery was aku (skipjack tuna), which was caught by a live-bait, pole-and-line, wooden sampan fleet, known

When the two sides come together, the argument boils down to one major point, should we “Free Willy?” Those who side with the whales, whether their reasons be emotional or defended with welfare standards, feel that the whales should be released back into the wild or into private coves3. The opposing side makes valid arguments against the release of the currently captive whales. Currently captive whales were either removed from the wild at a young age, albeit in a cruel way, or they were bred in captivity11

The Evolutionary History of Baleen Whales Dailynn Tejeda Hazleton Area Academy of Sciences The Evolutionary History of Baleen Whales The baleen whale family houses the largest whales that are currently known to man, leaving many scientists questioning as to how, and why, these whales evolved to become so humungous, when millions of years ago they were much smaller. Questions as to how they evolved to only feed on minuscule prey are also raised when speaking about baleen whale evolution

Sea World did not get rid of Tillicum knowing that workers could die, but they wanted to wait until the whale died. At the age of 36 years old all of the trainers went on a boat to see the whales because they are so friendly until they get irritated. Why are people coming to SeaWorld even if trainers are getting killed because it shows how many people like animals. The other whales beat up Tillicum maybe that is why he started killing. Sea World lies to the people they say that they die at the age

The documentary " The Cove" showcases an ethical dilemma in which Richard O'Barry learns the cruelty that dolphins face when in captivity and thus overcomes many barriers to help free the dolphins. Throughout the film, Richard O'Berry and others are involved in various illegal and unethical activities that include lying, spying, destroying property, trespassing and many more. As a former dolphin trainer for one of the most popular shows of the century " Flipper", had brought in a lot of popularity

“We won’t have a society if we destroy the environment.” Many environmentalists believe this is true when it comes to businesses overruling the environment in so many cases. In the Japanese dolphin slaughters is a prime example of that. The dolphin slaughters are eventually going to cause an entire species to become extinct because they are killing around 20,000 bottlenose dolphins per year. Taiji, alone, kills more than 2,300 Bottlenose Dolphins during the hunting seasons (Glionna). Japan likes

Many people may have seen the American reality TV show, "Whale Wars," it was broadcasted from the year 2008 to 2015. The show was about a group of activists' harassment and fight against the Japanese whaling ship. How the show depicted the fight between a group and Japanese ship was controversial, the show was cut off without a conclusion about this battle, but it concluded in me that the issue has to be ended without such fight. As a native Japanese myself, the Whale catching has been a controversial

1. Do you agree with the Norwegian and Japanese position on permitting the hunting of non-endangered species of whales as a cultural exemption? Yes. I strongly agree with the position of the Norwegian and Japanese governments to permit the hunting of non-endangered species as a cultural exemption. Since the whales they seek to hunt are not endangered, its not an environmental reason to ban whaling of species. Furthermore, whaling has always been a part of their culture as the local fishermen hunts

Last week I was made aware of the conflict regarding whaling between Japan, and others, and the rest of the international community opposed to the practice. This is a serious problem, and it becomes immediately clear that neither side is entirely devoted to the conservation of these animals in the strict sense. After decades of unregulated whaling, the International Whaling Commission was formed in 1946 as a “Global body charged with the conservation of whales and the management of whaling”. (IWC

Is the International Whaling Commission Effective against Japanese Whaling? No, it is not effective because there is corruption. Debuting in 1946 with only 14 members, the International Whaling Commission (IWC) was established with the signing of “The International Convention”. Now, the IWC has 89 member countries making it the world’s “whaling regulator.” Abiding the international regulation system, the Convention provides protection worldwide for all species of whales from over-fishing with

What Whale Poaching Really is By: Logan B I believe whale poaching should be outlawed around the world. Bans have warned people to stop hunting the whales but still over 2,000 whales are killed each year. In 1958, thirty eight thousand whales were killed since then, the amount of whales killed has dropped to thirty six thousand whales from that time. There are almost four whales killed each day. If someone is caught violating the laws it will result in civil penalties up to $11,000 or criminal

Dear Editor Why do humans think that our lives have more value over animals lives? Whales have existed on this earth far before we did, yet we still use our power to control these victims and take bits and pieces from their lifeless bodies as we please, as if they were put on this earth for humans to slaughter. Whales are not commodities. The Sea Shepherd Conservation Society which I am the president of frequently endeavours on dangerous expeditions to protect and defend marine wildlife from poaching

Although the whaling industry has been around for thousands of years, whaling became an extremely popular an effective business in America in the 19th century, specifically from 1846-1852. Even though whaling was a dangerous occupation to pursue, economically, it proved America with large amounts of oil and meat from the whales. The oil from the blubber was used for fuel in lamps, for making soap, for candles, and for margarine. When a fleet would journey on a whaling voyage, they would have a large

Yes I personally agree with the Norwegian and Japanese positions Firstly because, this is a non-endangered species of whales in these regions, thus has no environmental effects Secondly, the governments of these two countries have seek for an exemption on cultural grounds from an International Whaling ban, at a U.N. Conference on trade in endangered species that whaling constituted an integral part of their cultural heritage; Also the fact that, many International agreements, especially trade
