Eastern Atlantic: Cape Verde and Mauritania to northern Namibia (Ref. 244, 5578); possibly extending north to Morocco. Record from the Northwest Atlantic, specifically in New England, has not been verified even after an extensive survey of the area has been conducted.
A very common inshore to offshore shark of the continental shelf occurring at depths of a few meters to slightly over 100 m (Ref. 244). A specialist feeder that prefers cephalopods, also feeds on small bony fishes (Ref. 244). Viviparous (Ref. 50449). Utilized fresh and dried salted for human consumption, and processed into fishmeal (Ref. 244).
