Small, generally gray, streamlined shark, with long pointed snout. Posterior margin of anal fin straight or slightly concave. Second dorsal fin origin well behind anal fin origin (Ref. 26938).
Body shape (shape guide): fusiform / normal.
Reaches at least 103 cm TL (Ref. 244). Abundant in the continental shelves, from the intertidal to deeper waters. Often occurs close to the surf zone off sandy beaches, and also enclosed bays, sounds, and harbors, in estuaries and river mouths. Feeds on small bony fishes, shrimps, crabs, segmented worms and mollusks (gastropod feet). Viviparous, with 1 to 7 young in a litter (Ref. 27549). Size at birth about 29 to 37 cm. Utilized for human consumption. Minimum depth from Ref. 055195.
Distinct pairing with embrace (Ref. 205). Viviparous, placental (Ref. 50449). 1 to 7 young per litter. Larger females carry more young. Size at birth 29-37 cm. Gestation period is 10 to 11 months in the northern Gulf of Mexico. Sex ratio of near term fetuses is 1:1 (Ref. 244).
