Found inshore, at depths less than 20 m (Ref. 9840). Migrates in groups into shallow sandy areas during the rising tide to feed on molluscs, worms, shrimps, and crabs; disperses on falling tide to seek shelter in caves and under ledges (Ref. 6871). Disk width about 95 cm. Reports of specimens reaching 240 cm TL are probably inaccurate (Ref. 6871). Taken mainly by traditional fishermen (Ref. 9840).
