Why are rays related to sharks?

Stingrays and sharks are very closely related. Both are elasmobranchs, a subclass of fishes with cartilaginous skeletons, and five to seven gill slits. Beyond these similarities, both classes of fish inspire a certain sense of awe - that often has more to do with myth than fact.

Do stingrays have skeletons?

Stingrays are members of the group of fish that also includes sharks and skates. Sharks and rays have skeletons made of flexible cartilage instead of bone. What makes rays unusual is that their wing-like fins stretch out flat from their bodies, making them look like a disc with a tail.
