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 mollusks and crustaceans, crushing their shells with their flattened teeth. They are excellent swimmers and are able to breach the water up to several metres above the surface. Compared with other rays, they have long tails, and well-defined, rhomboidal bodies. They are ovoviviparous, giving birth to up to six young at a time. They range from 0.48 to 5.1 m (1.6 to 16.7 ft) in length and 7 m (23 ft) in wingspan.[1]
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.[2] White (2014) retained three genera (Aetobatus, Aetomylaeus, and Myliobatis) in the Myliobatidae, while a fourth (Pteromylaeus) was synoymized with Aetomylaeus.[2] A 2016 paper placed Aetobatus in its own family, the Aetobatidae.[3]
