From OpenwaterpediaHihimanu in Hawaiian) are a group of cartilaginous fish 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, while devil and manta rays filter plankton from the water. 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 rhomboidal bodies. They are ovoviviparous, giving birth to up to six young at a time.
Eagle rays live close to the coast in depths of 1 to 30 m and in exceptional cases they are found as deep as 300 m. 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.
