Description

The milk shark is a small, slender requiem shark of the family Carcharhinidae reaching about 1.8 metres, though usually smaller. The grey-brown, streamlined body has a strikingly long, pointed snout and large eyes. The species lives in schools in shallow coastal water and estuaries of the eastern Atlantic along West Africa and is widespread in the Indian and western Pacific; it tolerates brackish water. It hunts mainly small fish, shrimps, squid and crustaceans. The milk shark is viviparous and bears a few young per litter. It is one of the most common coastal sharks and harmless to people, but through intensive coastal fishing it has declined and is assessed as Near Threatened (NT).
