Spotted Eagle Rays :: MarineBio Video Library[1]

Spotted eagle rays, Aetobatus narinari (Euphrasen, 1790), aka white-spotted eagle ray, bonnetray, and maylan, grow to at least 3.5[2] m disc width and 9 m total length and have a recorded maximum weight of 230[3] kg. Current research on this species may reveal that what is being called the white-spotted eagle ray may in fact be several species. The spotted eagle ray has a long snout, flat and rounded like a duck’s bill, a thick head, and a pectoral disc with sharply curved, angular corners, and no caudal fin; jaws usually with single row of flat, chevron-shaped teeth. Each tooth is a crescent-shaped plate joined into a band. They usually have numerous white spots on black or bluish disc; with white below. Long whip-like tail, with a long spine near the base, behind small dorsal fin.
