The eagle rays are a group of cartilaginous fishes in the family Myliobatidae, consisting mostly of large species living in the open ocean rather than on the sea bottom.
Eagle rays feed on , and , crushing their shells with their flattened teeth. They are excellent swimmers and are able to breach the water up to several meters above the surface. Compared with other rays, they have long tails, and well-defined, bodies. They are ovoviviparous, giving birth to up to six young at a time. They range from in length and 7 m (23 ft) in wingspan.
Classification
Nelson's book
Fishes of the World treats cownose rays, mantas, and devil rays as subfamilies in the Myliobatidae. However, most authors (including William Toby White) have preferred to leave the
Rhinopteridae and
Mobulidae outside of the Myliobatidae.
White (2014) retained three genera (
Aetobatus,
Aetomylaeus, and
Myliobatis) in the Myliobatidae, while a fourth (
Pteromylaeus) was synonymized with
Aetomylaeus.
[ A 2016 paper placed Aetobatus in its own family, the Aetobatus.]

|The common eagle ray, M. aquila, is distributed throughout the Eastern Atlantic, including the Mediterranean Sea, and the North Sea. Another important species is the bat eagle ray, M. californica, in the Pacific Ocean. These rays can grow extremely large, up to including the tail. The tail looks like a whip and may be as long as the body, and is armed with a stinger. Eagle rays live close to the coast in depths of and in exceptional cases, they are found as deep as . The eagle ray is most commonly seen cruising along sandy beaches in very shallow waters, its two wings sometimes breaking the surface and giving the impression of two sharks traveling together.
