Issue
The species Aetobatus laticeps Duméril, 1865 is considered as valid in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697) according to White et al. (2010: Ref. 84291) where it is questionably valid.

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. 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 (Ref. 5578). Each tooth a crescent-shaped plate joined into a band (Ref. 26938). Numerous white spots on black or bluish disc; white below (Ref. 5578).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Western Atlantic: North Carolina (summer) and Florida, USA and Bermuda to southern Brazil. Throughout Gulf of Mexico and Caribbean, including Antilles (Ref. 26938). 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 (Ref. 5530). There may be more than one species of spotted Aetobatus (Ref. 9862). Based on combined genealogical concordance and genetic distance criteria,

Biology     Glossary (e.g. epibenthic)

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 (Ref. 58302). Sometimes enters estuaries (Ref. 6871). Swims close to the surface, occasionally leaping out of the water, or close to the bottom (Ref. 3175). Frequently forming large schools during the non-breeding season (Ref. 7251). Feeds mainly on bivalves but also eats shrimps, crabs, octopus and worms, whelks, and small fishes (Ref. 9862). Ovoviviparous (Ref. 50449). Flesh edible (Ref. 30573). Over 3 m disc width and up to 880 cm total length if the long tail is undamaged (Ref. 30573). Bears young in litters of 2-4 (Ref.58048,Ref. 26938). Tail used as a decorative item (Ref. 27550). Common catch of the demersal tangle net, bottom trawl, inshore gillnet and, to a lesser extent, demersal longline fisheries. Utilized for its meat and cartilage (Ref.58048).
