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

Whaling, which has been in practice for centuries, involved hunting and killing whales in order to obtain oil, meat, or bone. In past years, it has proven controversial and has brought up the question as to whether or not whaling should continue. In order to get a full glimpse of this issue, we need to gather the pros and cons to whaling. By doing this, we can truly assess whether or not whaling is something that should be carried on and legalised. In the Faroe Islands, there is an old saying which

The Whaling Ban Issue Globalization University of The People In order to preserve their cultural activities the Norwegian and Japanese people are opposing to the whaling ban which has been issued. Some villages’ main income was based on whale hunting and the ban is making the life of locals difficult. From a cultural activity that finds most of the world opposite, the people of these areas were providing for their families depending on the particular hunt. After pausing for a second on

Manatee - Florida manatee Introduction: The Florida manatee (Trichechus manatus) is a marine mammal which is also known as “West Indian manatee” or North American manatee. Manatees are occasionally called sea cows as they are similar to cows on land. Manatees belong to the family Trichechidae. This manatee is the largest, fully aquatic surviving member of the aquatic mammal “order Sirenia”. The lifespan of the manatee is 50-60 years in the wild. It is known that manatees have good long-term memory

Introduction Whale hunting in Japan has become an increasingly controversial topic after the International Whaling Commission law was passed because Japan has been killing large number of whales for scientific research. This is because of that some of whales’ species such as blue whales are considered endangered and this might cause an ecological damage to the sea environment. Whales are intelligent animals and their existence participate in the environmental equilibrium therefore killings

Japan and Norway, along with other countries, have sought cultural exemptions for whaling in the last few decades and such allowances should be made within certain qualifiers. At the core of the issue is the United Nations Conventions on the Law of the Sea (UNCLOS), the United Nations International Covenant on Economic, Social, and Cultural Rights (ICESCR), and the moratorium on hunting whales by the International Whaling Commission (IWC). In 1986 the IWC made a blanket moratorium on whaling and

It was a sunny day, the sun is high up in the sky and I woke up with a smile on my face, I remembered that we are going on a trip to San Diego. My mom woke up early in the morning to make breakfast for the family. The breakfast for that morning was an egg with sausages and bacon, those foods were my favorite breakfast foods. Breakfast time was almost over, dad woke up and started to put the baggage into the car. We started driving on the road as soon as we finished our breakfast. The road was beautiful

There is always a new bandwagon for false activists, and one of the most popular is the cause of freeing captured killer whales. For some, this is not just the latest fad, but it has been a life long devotion which has been the focus of their passion since the mid twentieth century. These creature are majestic and need to be protected. They were named after this frightening figure because of their brutal reputation in the wild. In Latin, the word Orca can literally be translated to barrel-shaped

Feeding techniques and Social Learning: Bubble net feeding has been identified as tool-using behavior and a possible sign of culture. The process of bubble-net feeding is like a game of football, where members specialize in an specific factor of the hunting process. From the evolutionary perspective, humpback whales could have develop cultural transmission in order to communicate about the location of the their prey. Their prey, schools of fish, are spread in aggregated manners

The Norwegian and Japanese positions and arguments to be permitted with the hunting of non-endangered species of whales as a cultural exemption should not be considered. According to the Whale and Dolphin Conservation, “the whaling industry is in decline and the demand for meat is falling” (WDC, n.d.). Given this statement, I would support the ban of whaling worldwide. In addition, it would be difficult and costly to monitor the whaling activity that is taking place in waters where whales frequent

For decades, Australia has cleared land, destroyed native wildlife habitat and not to mention ongoing cruelty to kangaroos, wombats and emus. All to “protect” these sheep, who lives are absolute hell, only to have it end on horrible ships. But, do you know what is actually going on in these ships? Each year, Australia exports over four million live sheep to the Middle East. But, around 40,000 sheep die every year even before they reach their destination. In a country, on remote properties, it starts

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
