A small, relatively common inshore and offshore shark of tropical continental seas (Ref. 13567). Feeds mainly on cephalopods, particularly octopi (Ref. 13567) but also takes crustaceans and cephalopods (Ref. 244). Viviparous (Ref. 50449). Taken regularly in inshore artisanal fisheries (Ref.244), commonly caught by inshore gillnet, bottom trawl and, to a lesser extent, longline fisheries. Utilized for human consumption (Ref. 244). Offal used for fishmeal (Ref. 244).
