These rays live in shallow coastal waters and can be found singly or in large shoals. The feed on crustaceans mostly, but will sometimes feed on shoals of smaller fish. Lesser devil rays are relatively small, with a maximum length of 120 cm. They have smaller cephalic fins than their larger manta cousins and have longer spineless tails.
The lesser devil ray has tasty flesh and is a good source of oil. They are known to swim at very high speeds and leap out of the water, often a great distance.
