The exception of the northeastern Pacific Ocean. In the western Atlantic Ocean, this shark ranges from North Carolina (USA) and the northern Gulf of Mexico to Cuba and from Venezuela south to Argentina, and in the eastern Atlantic from Morocco to Namibia, including the Mediterranean Sea. It is also found in the Indian Ocean in waters off southwestern India, Aldabra Island, southern Mozambique, and South Africa. Distribution in the Pacific Ocean occurs from Japan to China, Indonesia, Australia, and New Zealand, as well as off the coast of northern Chile (Compagno 2001).
Habitat
As a deepwater species, the sharpnose sevengill lives in continental and outer island shelf waters at depths of 27–1000 m (89–3,280 ft) (Castro 1999). It is usually found on or near the bottom, although it is occasionally observed near the surface (Castro 1999). Its wide distribution suggests that the sevengill shark is probably a strong swimmer.
