Batoidea is a superorder of cartilaginous fishes containing more than 500 described species in thirteen families. They are commonly known as rays, but that term is also used specifically for batoids in the order Rajiformes, the "true rays". Batoids include stingrays, skates, electric rays, guitarfishes and sawfishes.

Batoids are most closely related to sharks and young batoids look very much like young sharks. Indeed according to recent DNA analyses the catshark is more closely related to the batoids than to other sharks
