Description
Size (male): 65-330 cm WD.

Max. published weight: 230.0 kg.

Color: Numerous white spots on black or bluish disc; white below.

An eagleray with 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 a crescent-shaped plate joined into a band. Long whiplike tail, with a long spine near the base, behind small dorsal fin. No spines on disk. Dorsal spines (total): 0; Anal spines: 0.

Dioecism, internal fertilization, bearers, exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures. Bears up to 4 young. Width at birth 17-35 cm. The male chases the female in mid water, then nibbles on her dorsal surface. The female stops swimming to begin copulation. The male bites the female on a pectoral fin and bends one clasper forward, then attempts an abdomen to abdomen copulation with either clasper, usually mid-water. Copulation lasted for 20 seconds to 1 minute.
