Oceanic dolphin Essays

Based on the evolutionary pattern of whales and dolphins, we can see that they are of divergent evolution; in which a trait held by a common ancestor evolves into different variations over time. This report will endeavour to prove that theory, and explain why whales and dolphins have a divergent evolution. Whales and dolphins are often called cetaceans when referring to both species. The cetaceans are a marine mammal, descendants of land mammals. A cetacean is an aquatic species that needs air from

species, particularly the raw sashimi market. They are the second tuna species in terms of volume and popularity. They are extremely fast swimmers and tend to aggregate in schools especially with fish of the same size as well as with various species of dolphins or porpoises. Yellowfin tuna, travel long distances. They have a life expectancy of about 8 years. Distribution and habitats: The yellowfin tuna (Thunnus albacares) is found in pelagic waters of tropical and subtropical oceans worldwide except for

In 2013, Gabriela Cowperthwaite directed the documentary Blackfish. This documentary is about Tilikum, an orca from SeaWorld that has taken the lives of many trainers. The documentary makes the claim that orcas should be freed from captivity. While in captivity they are causing harm to both themselves, humans, and the other orcas. Blackfish is a great example of an argument that can be rhetorically analyzed because it has pathos, ethos, and logos. The target audience of this documentary is the

The Negative Effects Captivity has on Orcas Orcas, also known as killer whales, have been captured and placed in captivity beginning in 1961. Not only were orcas captured and brought into captivity, many were born into captivity. An increasing amount of Orcas in captivity has started a serious conversation on whether Orcas are benefiting or suffering from being held in captivity. There are differing opinions about captivity having a positive or negative effect on the Orcas well-being. There are

suffering animals, stated, “Dolphins in the wild may swim up to 40 or 50 miles in a day and can dive to depths of hundreds of feet. Even in the largest captive facilities, dolphins have access to less than 1/10,000 of 1% (0.000001%) of the space available to them in their natural environment.” Dolphin captivity is when people keep dolphins in closed-in areas and own them for educational purposes or entertainment purposes. Dolphin circuses are groups of people who keep dolphins, normally illegally, to

Ecology and behaviour The southern right whale (Eubalaena australis) is a medium to large baleen whale, reaching a maximum length of 17.5m. Colour patterning is variable, ranging from black to grey-brown (Harcourt et al. 2012). Distinguishing features include a rotund body with no dorsal fin and callosities (caused by colonised cyamids, small crustaceans, on keratinised skin patches) on the head (Harcourt et al. 2012). Each individual has a unique callosity pattern that occurs a few months after

SCOLIODON The Chondrichthyes are also known as elasmobranchs. They are almost exclusively marine and include sharks, rays, and chimaeras. Scoliodon is an elasmobranch which is marine and is an active swimmer. Scoliodon is widely studied shark all over the world. The genus is represented by nine species, of which four are very common in Indian seas.It is commonly known as the Dog fish. Scoliodon was first discovered and described by Muller and Henle (1837).

Pollution and human impact has been wrongfully hurting West Indian Manatees The manatee is a big sea mammal that is also known as the sea cow. The manatees weigh about 650 lbs and are nearly 8.5 ft. long on average. The West Indian manatee lives in the warm waters off the coast of Florida. The West Indian manatee was placed on the endangered species list in 2016, the manatee has recently been moved to the threatened list due to the many people gathering together and to help and save the manatees

146 orcas have died in captivity, and 48 of those orcas have died at SeaWorld. The average person believes that orcas, also known as killer whales, are in captivity for their own well being, or to research their species, but that is false. Killer whales are tortured to do our bidding, for other people's entertainment and greediness. The orca trainers limit their food rations so that they become hungry enough to want the “food treat” after they do the tricks that are force upon them. Orcas do not

Blackfish was released, a story about a killer whale that over the years at SeaWorld killed several people. It highlighted some of the major problems with animals in captivity. SeaWorld, known for having several different animal attractions; Dolphin Cove, Dolphin Nursery, Orca Underwater Viewing, Shark Encounter, Wild Arctic (Habitat) and many more. The organization first started with the intention of learning more about animals in order to educate the public about different behaviors of each animal

aquarium in the United States. The aquarium strives to help inspire people on how important it is to preserve the beauty of the ocean and also why some species are becoming endangered. The aquarium is an iconic landmark offering marine-life exhibits, a dolphin show, shark tank and walk-through rain forest. Every year the aquarium has a new exhibits and shows for the public.

For years people have been captured by the beauty and grace of Orca whales. SeaWorld is a big reason for this love to watch the whales before. There they have designated time slots where the whales and trainers come out and perform a show with several jumps as well as the animals will spray the surrounding audience. The whales and their trainers form a bonds with certain whales not all the whales get along with a person. A trainer from SeaWorld described it as signs that the whale would show to

Mass dolphin murder is one of the many issues that are happening in our world today in the 21st century. The Documentary Called “The Cove” would make the viewers open their eyes of what this world actually is and the secret Taiji, Japan is trying to keep. This situation would show us why these activists struggle so hard to stop this social issue. One of the reasons being, the mass murder by the fishermen, and the captivity of the dolphins by the Sea World’s organization. Dolphin meat is sold illegally

Blackfish By Kirstin O’Neill The blackfish article and the movie are arguing about the captivity of the whales and how they harmful and how they are not. So the documentary had said that the whales are more aggressive in captivity than in the wild.The article claims that whales live longer in captivity than in the wild.

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

Think of yourself as this Atlantic Bottlenose Dolphin right now when I read this. The Atlantic Bottlenose Dolphin usually lives near the surface of the water, but sometimes it can dive as deep as 2,000 feet. Dolphins have more blood for their body size than do land animals, so they are able to store more oxygen. Dolphins can store twice as much oxygen in their muscles as humans. Also, during deep dives they can partially collapse their lungs and specially hinged ribs. This helps them to stay under

So let’s say that you were an orca or a dolphin and you were held in captivity against your will by another human being. How would you feel about this situation? Well, in the case of many unfortunate aquatic mammals in marine parks and zoos around the world, most of these magnificent animals are held captive in tanks with no room to roam around, or have to deal with being alone, which can trigger stress and aggression. Over the years since the Nineteen sixties, the first marine mammals were put into
