Size/Age

Adults mature between 2 and 3 feet long (about 2-4 years of age) and rarely grow more than 3.5 feet long. Maximum observed ages in recent studies have shown this species can live up to at least 9 years.

Habitat

Coastal waters; can be found near the surf zone; common in bays and estuaries.

Adults also found offshore.

Feeding

Feeds on small fishes (baitfish, jacks, and silversides) and invertebrates (crabs, shrimp, and mollusks).

Reproduction

Pregnant females migrate offshore after mating occurs in late spring and early summer.  Females return 10-11 months later to give birth to live young in nearshore areas. Broods contain 4-7 pups. Size at birth 11-15 inches.

Additional Information

This abundant, small coastal shark is caught frequently and targeted for their meat. However, their small fin size makes them less valuable to commercial fisheries than other species of shark. Commonly caught as bycatch in the shrimp fisheries.
