The rays, or batoids, are a group of cartilaginous fish containing more than 500 described species in thirteen families. They include four orders.
Rays are mostly flattened in shape, and usually demersal, living and eating at the bottom of the sea. The group first appears in the Triassic period, after 95% of marine species had been wiped out by the P/Tr extinction event.
