Eastern Atlantic: Senegal to Gambia. Western Mediterranean around the coast of Spain. Pacific: China, Hawaii and Gulf of California, southern Mexico, Columbia, and Ecuador.

 Biology

A common offshore species, mainly bottom-dwelling in deeper water. Can be found preferably in depths between 250 and 430 m.

 Feeding

Feeds on fishes (batfish, soles, lizardfish...) and other sharks including dogfish (Squalus sp.), cat sharks (Holohalaelurus sp.) or rays (Dasyatis sp.).

 Size

Sandbar sharks give birth at different times in different areas, August and September in the Mediterranean, September and October around Madagascar.

 Similar Species

 Danger to Humans

This species does not seem to be a threat to people because of its deepwater habitat.
