Abstract

Steven Spielberg, Jaws, and numerous aquaria have made most Americans aware of the sinuous grace of a shark moving through the water. Much of that ease of movement comes from the shark’s lack of bones. Their skeletons are made of cartilage, a soft and flexible material, a material so admirably suited to life in the oceans that sharks have changed little in several millions of years.
