Short Description
An eagleray with a long snout, flat and rounded like a duck"quot;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 [536]. Each tooth a crescent-shaped plate joined into a band [17659]. Numerous white spots on black or bluish disc; white below [536]. Long whiplike tail, with a long spine near the base, behind small dorsal fin. No spines on disk [17658].

Distribution
Western Atlantic: North Carolina (summer) and Florida, USA and Bermuda to southern Brazil. Throughout Gulf of Mexico and Caribbean, including Antilles [17659]. Eastern Atlantic: Mauritania to Angola (Ref. 4440). Indo-West Pacific: Red Sea and South Africa to Hawaii, north to Japan, south to Australia (Ref. 9862). Eastern Pacific: Gulf of California to Puerto Pizarro, Peru and the Galapagos Islands [455]. There may be more than one species of spotted Aetobatus (Ref. 9862).

Human uses
fisheries: minor commercial; gamefish: yes; price category: medium; price reliability: very questionable: based on ex-vessel price for species in this family

Biology
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 [733]. Bears up to 4 young [1388] (Ref. 5578, 37816). Width at birth 17-35 cm (Ref. 37816). According to Uchida et al (1990) (Ref. 51119) "quot;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"quot; (Ref. 49562). Copulation lasted for 20 seconds to 1 minute (Ref. 49562). Commonly found in shallow inshore waters such as bays and coral reefs but may cross oceanic basins (Ref. 9862). Benthopelagic, found near land at 1-60 m [17640]. Sometimes enters estuaries [1388]. Swims close to the surface, occasionally leaping out of the water, or close to the bottom [7176]. Frequently forming large schools during the non-breeding season [17658]. Feeds mainly on bivalves but also eats shrimps, crabs, octopus and worms, whelks, and small fishes (Ref. 9862). A carnivore [17641].
