Myliobatidae

 

(eagle rays), a family of fishes of the order Batoidea. The rhomboid body has acute angles; the head is easily distinguished from the rest of the body. The tail resembles a long knout and, in some species, is equipped with dentate needles. There are five genera of eagle rays, embracing about 25 species. Some species measure as much as 2.5 m across and reach a length, including the tail, of 4.5 m. Eagle rays weigh up to 300 kg. They are ovoviviparous, producing six or seven young. The fishes are distributed in warm littoral waters of the World Ocean. They feed predominantly on mollusks. When eagle rays move, they wave their large fins and seem to fly in the water. Sometimes they leap to the surface and jump above the water. The flesh of eagle rays is edible, but the fishes are not commercially valuable.
