    The Whale is a large, magnificent, intelligent and aquatic mammal. They breath from a hole on top of their head called a blowhole, into their lungs. The whale has a very smooth skin that covers their very streamlined body that moves easily through the water. They are the only mammal that has adapted to life in the open oceans. Whales are considered to be "cetaceans  which means various aquatic life chiefly marine mammals of the order cetacean, including whales, dolphins and porpoises, characterized by a nearly hairless body, broad flippers and a flat notched tail. There are 75 species of Cetaceans, but the two groups are toothed whales and baleen whales. Toothed whales are predators that use their peg-like teeth to catch fish, squid and marine mammals. They swallow them whole. They have one blow hole and use echolocation to hunt. Echolocation is an high pitched sound sent out by the whale. It bounces off the object and then returns to the whale. This tells the whales the shape, direction, distance and texture of the object. Baleen whales are predators that sieve tiny crustaceans, small fish and other tiny organisms. Baleen whales have a comb-like structure that filters the food from the water. They are larger than the toothed whales and have two blow holes. There are less species of baleen whales.…

    Baleen whales undergo the longest annual migrations of any animal (Rice and Wolman 1971, Stone et al. 1990, Rasmussen et al. 2007). The function has generally been accepted as an evolutionary response to the need to feed in colder waters and reproduce in warmer waters (Corkeron and Connor 1999, Learmonth et al 2006). The location of feeding and breeding grounds along migration routes were initially inferred from stomach contents of stranding data and whaling logs (e.g., MacKintosh 1945, Scammon…
