It’s a bird… it’s a plane… it’s a bat! All three may be soaring through the sky, but their shapes vary greatly, which affects their aerodynamics during flight. Birds typically have streamlined head.

The cetacean skeleton is largely made up of cortical bone, which stabilizes the animal in the water.For this reason, the usual terrestrial compact bones, which are finely woven cancellous bone, are replaced with lighter and more elastic material.In many places, bone elements are replaced by cartilage and even fat, thereby improving their hydrostatic qualities.
