Etymology: Aetobatus: Greek, aetos = eagle + Greek, batis, batidos = a ray (Raja sp.) (Ref. 45335).

Issue
Status of Aetobatus latirostris Duméril, 1861 requires further investigation. Species information (common names) should be linked to correct species (see Ref. 114963).

Descrição breve Morfologia | Morfometria

Espinhos dorsais (total): 0; Raios dorsais moles (total): 0; Espinhos anais 0; Raios anais moles: 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). Long whiplike tail, with a long spine near the base, behind small dorsal fin. No spines on disk (Ref. 7251).

Biologia     Glossário (ex. epibenthic)

Commonly found in coastal habitats to at least 60 m depth (Ref. 114953). 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 on polychaetes, bivalves, gastropods, cepahlopods, shrimps and small fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Bears young in litters of 2-4 (Ref. 26938, 114953).

Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

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 (Ref. 50449). Bears up to 4 young (Ref. 5578, 6871, 37816). Width at birth 17-35 cm (Ref. 37816). According to Uchida et al (1990) (Ref. 51119) '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' (Ref. 49562). Copulation lasted for 20 seconds to 1 minute (Ref. 49562).
