Description

The bignose shark is a robust requiem shark of the family Carcharhinidae reaching about 3 metres. The grey, streamlined body has a long, broad snout with large nostrils - hence the name - large pectoral fins and a conspicuously high skin ridge between the two dorsal fins. The species is widely distributed in warm and temperate seas worldwide, including the Mediterranean, along the outer edge of the continental shelf and over the slope, usually in deeper water. Close to the bottom it hunts bottom fish, rays, small sharks and squid. It is viviparous. Because it is taken as bycatch in longline and trawl fisheries it is assessed as Near Threatened (NT).
