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).

Distinct pairing with embrace (Ref. 205). Viviparous, placental (Ref. 50449), with 5 to 17 embryos (Ref. 9253). Both male and female during precopulatory and courtship swim with body axes in parallel (Ref. 49562, 51112). During copulation, the pair performs coordinated swimming (Ref. 49562, 51112).西大西洋: 美國的紐澤西到巴西南部, 包括墨西哥灣，巴哈馬與加勒比海; 也在墨西哥灣.(參考文獻 26938) 東北大西洋: 塞內加爾, 象牙海岸與可能廣泛分佈外海的非洲西方部, 但是這需要證實。 東太平洋: 墨西哥的下加利福尼亞南部與加州灣到厄瓜多。
