Together as the carpus, it is the vital part of the skeleton that holds together the small and large bones in the human hand, stabilizing its dorsal and palmar sides [6]. All whales have a layer of superficial blubber, which insulates and streamlines, provides buoyancy and acts as an energy reserve. There aren’t any bones … The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale.

The blowholes are connected directly to the lungs, so the whale can take a … 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). In most animals, the pelvic bones are needed to be able to move the lower or rear set of limbs for the purpose of locomotion. To determine whether whale pelves still have a function, Otárola-Castillo and his colleagues created detailed computerized models of the pelvic bones of more than 100 species, and used custom-designed software to examine their shapes in three-dimensional space. The purpose of the baleen is to act as a sieve, catching tiny organisms in sea water, which the whale consumes as food. All tetrapods (including whales) have pelvic bones.
