Description

The spotted eagle ray is a large, graceful ray of the family Myliobatidae (eagle rays) reaching a wingspan of about 2.3 metres. The diamond-shaped body has broad, pointed 'wings' and a striking duck-bill-like head; the black upper side is covered with white spots, a pattern unique to each animal. The long, whip-like tail bears one or more venomous spines. The species swims gracefully and pelagically above sand bottoms, reefs and lagoons of tropical and subtropical seas worldwide, often in loose groups, and sometimes leaps from the water. With flat jaw plates it crushes shellfish, crabs and crustaceans. Through fishing and bycatch it has declined and is assessed as Endangered (EN).
