Distribution
Western Atlantic: Maryland, USA to Brazil. Also Gulf of Mexico and northern South America to Brazil [17659]. Eastern Atlantic: Senegal, Gambia, Sierra Leone, Cameroon and Democratic Republic of the Congo (to the mouth of Congo River) (Ref. 4439). Reported from Mauritania (Ref. 55783). Nominal records from off Sri Lanka, India, Malaysia, Singapore, Viet Nam, Borneo and Sumatra in Indonesia, and the Philippines need to be verified if indeed it is the same species that occurs in the Atlantic (Ref. 9918).

Biology
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures [733]. Distinct pairing with embrace [17086]. Reproductive biology (data from 905 individuals were sampled, 377 of which were used for the reproductive study): Size at birth ranged from 135 to 175 mm WD (19·5 to 55·0 g), with a mean of 165·1 mm WD (43·3 g). The embryo sex ratio was not significantly different from 1:1. The ovaries of pregnant females were undergoing vitellogenesis during gestation, with females ready to ovulate soon after parturition. [16817] Feeds on fish and shrimps [20216].
