Short description

A brownish shark with yellow overtones but no conspicuous markings. Large second dorsal fin nearly same size as first dorsal (Ref. 26938).

Occurs on continental and insular shelves, frequenting mangrove fringes, coral keys, docks, sand or coral mud bottoms, saline creeks, enclosed bays or sounds, and river mouths. May enter fresh water. Occasionally moves into the open ocean, near or at the surface, apparently for purposes of migration. May rest motionless on the bottom (Ref. 9710). May occur singly or in small groups. Feeds mainly on fish but also takes crustaceans and mollusks. Viviparous, with 4 to 17 young in a litter. Size at birth 60 to 65 cm. Has been involved in several attacks on people. Meat is utilized for human consumption, hides for leather, fins for shark-fin soup base, liver oil for vitamins, and carcasses for fish meal. Marketed fresh, dried-salted and frozen (Ref. 9987).
