A little-known shark found on the continental and insular shelves (Ref. 244). Reports from river mouths and rivers are based on old records that need verification (Ref. 9997). Probably feeds on small fishes, cephalopods, and crustaceans (Ref. 9997). Viviparous (Ref. 50449). Utilized fresh for human consumption (Ref. 9997).
