Since cetaceans descended from land mammals, their skeletal structure is very similar to that of their land relatives. Surprisingly whales cannot breathe through their mouth like humans and most land based mammals because their esophagus (food passage) and trachea (air passage) are completely separated from each other. In Arctic whales a higher proportion of unsaturated, versus saturated fatty acids make up the lipid. Whale bone structure is very similar to an artiodactyl’s bone structure. Because these large marine mammals do not possess teeth they end up swallowing their food whole so they frequently hunt for small manageable prey that is easily consumable and tend to look for large swarms of fish, squid or krill to consume. The whale shark is enormous and reportedly capable of reaching a maximum length of about 18 metres (59 feet). The sk\൥leton of a humpback, however, accounts for only 15% of its body weight. 2007.

Recently, the possible role of fibroblast growth factors (FGFs) on whale … The thick blubber helps keep the cold/freezing temperatures of the outside water away from the whales vital organs and can even protect whales against attacks from predators such as sharks and killer whales. Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007). Recent research has uncovered new details about the critical function of whale … The more closely organisms are related, the more similar the homologous structures are. Instead of enamel which is found on the teeth of humans humans a whales teeth is covered in cementum cells and unless the cementum is worn down you won’t be able to see the enamel on their teeth.

Cancellous (spongy) bone, with a highly porous angular network of trabeculae, is less stiff and thus found in whale ribs and vertebrae (Turner Walker 2012). Richard Owen, a rising star in the academic community, carefully scrutinized every bone, and he even received permission to slice into the teeth to study their microscopic structure. The remaining non-utilized pelvic bones in whales and manatees are examples of vestigial structures.
