Also called: baleen a horny elastic material forming a series of numerous thin plates that hang from the upper jaw on either side of the palate in the toothless (whalebone) whales and strain plankton from water entering the mouth Each bone is an organ that includes nervous tissue, epithelial tissue (within the blood vessels), and connective tissue (blood, bone, cartilage, adipose, and fibrous connective tissue). They have become wings for flying in birds and bats, flippers for swimming in whales, seals and porpoises, fast and efficient limbs for running in horses and arms and hands for holding and manipulating in primates (see diagram 6.8). Whale ribs loosely articulate with their thoracic vertebrae at the proximal end but unlike land mammals, they do not connect with a sternum to form a rigid 'rib cage'. Baleen whales are larger than the toothed whales. There are eight carpal bones: the scaphoid, the capitate, the trapezium, the trapezoid, the lunate, the triquetral, the pisiform and the hamate. A Whale of a Pelvic Bone . Comparative Anatomy of Whales We can first look at the homologous structures in whales. The function of the carpals is to allow for the easy and free movement of the wrist.
