Like other sharks, the female is normally larger than the male sharks are. Also, pregnant females have been found containing hundreds of pups, which means that whale sharks are viviparous. This means giving birth to live young, and these newborns are over two feet long.

Off the coast of California Sea Otters feed off of over forty marine invertebrates including abalone, mussels, sea urchins, clams, crabs and snails to name a few. Putting themselves in an elite category of mammals, Sea Otters use tools to pry food from rocks, or to smash open shells. Their catlike claws retract like a cat's for grooming and eating which is important as they eat twenty to twenty five percent of their body weight each day. Not only that, but they have a built-in dinner table: their bellies. They even have pockets of skin under the forelegs to stash food for their trip from sea bed to water's surface.
Most of the adult of this species are feeding on the marine plants life such as kelp and the algae while the young prefer more carnivores feeding style. In addition, they also may migrate in long distance in order to obtain their foods covered by from feeding ground to the hatching beaches. In addition, their adult can grow up to 1.5 metres long with the average weight from 68 to 190 kg. Physically they have the flattened body which covered by a large teardrop-shaped carapace with a pair of large paddle-like flippers that are usually light in colour. This reptiles also have the short neck.
The four countries under this treaty are the U.S.,Japan, Great Britain and Russia. Throughout the 1750’s and 1911, a single fur coat could bring in 1,125 dollars. Although most of the poaching of sea otters has subsided, other factors have come into play (Fernandez, James). Pollution of kelp forests and oil spills are extreme threats to sea otters. Since the sea otter spends most of its life in the water, thousands are killed by oil spills.
(3) Baleen whales have a type of keratin called baleen that hangs in their mouths and sifts food from the ocean waters. (4) Baleen whales can consume up to 9,000 pounds of fish a day. (5) The toothed whale is the other type of whale. (6) The toothed whales have teeth instead of baleen. (7) They gnaw and chew on their meals.
Sustainable fishing Global fish production has reached an all-time high, according to Nourishing the Planet’s latest research for the Worldwatch Institute’sVital Signs Online publication. Aquaculture, or fish farming — once a minor contributor to total fish harvest — increased 50-fold between the 1950s and 2008 and now contributes nearly half of all fish produced worldwide.According to the United Nations Food and Agriculture Organisation, an estimated 53% of fisheries are considered fully exploited — harvested to their maximum sustainable levels — with no room for expansion in production. Population growth and a higher demand for dietary protein are putting increasing pressure on depleted stocks and threatened ecosystems. Increased farming of large predators, such as salmon and tuna, has led to overfishing of prey fish — including anchoveta and herring, which are commonly used as fishmeal. It generally takes at least three kilograms of feed to produce one kilogram of salmon.
Noedlene Pierre Professor Martinez September 28, 2010 EC1 ESL KILLER CUISINE In the article “Killer Cuisine,” author Krista Mahr speaks about the most uncommon and luxurious dish in Hong Kong, known as the shark-fin soup. Shark-fin soup gets its flavor mainly from the broth; the bland-tasting fin, sliced into noodle-like strips, and can cost up to one-hundred dollars a bowl. Mahr argues that the shark-fin soup should be banned and questions the importance of the soup ritual. Shark-fin soup is common at any big Chinese banquet; it is a representation of glamour and status, but is also the key reason why there are threats to our increasingly fragile ecosystem, cruelty in shark poaching, and why sharks are plummeting around the world. Like all animals, sharks are an important part of the ecosystem, without them the entire ecosystem will collapse.
