Etymology: Triakis: tri-, from tres (L.), three; akis (Gr.), point, referring to each tooth consisting of one large central cusp flanked on by both sides by a small cusplet. (See ETYFish); scyllium: From skylion, Greek for dogfish or small shark. (See ETYFish).

Found on the continental and insular shelves, often occurring in shallow water close inshore. Prefers estuaries and shallow bays, especially sandy and algal-covered areas and eelgrass flats. Feeds on small fishes and probably crustaceans and other benthic invertebrates. Often solitary, though some may cluster in resting areas on bottom. Ovoviviparous (aplacental), with 10 to 20 young in a litter. Meat is regarded as of inferior quality.
