Short description Identification keys | Morphology | Morphometrics

Large ray with a small caudal fin and with papillae around the spiracles (Ref. 5578). Bright color pattern of circles and irregular marks, cream or golden on dark red or brown to blackish background dorsally (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Found inshore in sandy bottoms, and well offshore from the surf zone down to 200 m (Ref. 5578). Also on or near coral reefs (Ref. 12951, Ref. 114953). Common in shallow sandy areas (Ref. 2712). Feeds on bony fishes (Ref. 12951) and benthic invertebrates (Ref. 114953). Ovoviviparous (Ref. 50449). Males mature by 30 cm TL (Ref. 114953). Occurs singly but may form groups during the breeding season (Ref. 12951). Occasionally hooked by anglers, more often seen by divers; can deliver a strong shock (Ref. 2712). Flesh is edible (Ref. 12484). Can survive for hours after being stranded on the beach (Ref. 41394).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

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). With 9-22 in a litter (Ref. 12951). Form aggregations during the reproductive season (Ref. 41394).
