Description

The night shark is a slender requiem shark of the family Carcharhinidae reaching about 2.8 metres. The grey-brown, streamlined body has a long, pointed snout and conspicuously large eyes with a greenish sheen, an adaptation to its nocturnal life in deep water. The species lives in the Atlantic on both sides, along the outer edge of the continental shelf and over the slope and seamounts. By day it stays in deeper water; at night it moves higher in the water column to hunt small schooling fish, squid and crustaceans. It is viviparous. Through fishing and bycatch the species has declined and is assessed as Vulnerable (VU).
