Characteristics


The average weight of Sandbar sharks is 110 pounds for males and 150 pounds for females. Their body is brownish or dark gray with a lighter belly. The snout is rounded and quite blunt compared to other species of shark. The first dorsal fin is notably large, and Sandbar sharks have an interdorsal ridge.

Behavior


Sandbar sharks feed throughout the day but become more active at night. When compared to other sharks in the family Carcharhinidae, the Sandbar shark seems to have a better feeding strategy.

Reproduction


These sharks are viviparous, giving live birth. After fertilization, there is an eight to nine month period for gestation in the western Atlantic population. The pups are born between June and August. Females living near the coast of southeastern Africa experience a 12-month gestation period, giving birth from December to February. The size of the litter also varies by region and size of the mother, but typically there are 6-13 pups per litter.
