Adults are found over soft bottoms, near rocky or coral reefs; also near reef drop-offs (Ref. 12951). They occasionally swim near the surface and may jump out of the water. Often in schools, sometimes associated with Aetobatus narinari, the spotted eagle ray (Ref. 12951). Adults feed on benthic crustaceans and mollusks. Ovoviviparous (Ref. 50449).
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).
