Description

The Atlantic weasel shark is a slender coastal shark of the family Hemigaleidae (weasel sharks) reaching about 1.4 metres. The grey, streamlined body has large eyes, a fairly pointed snout and several yellowish lengthwise stripes along the flank. The species lives in shallow coastal water and over the continental shelf along the West African coast, from Mauritania to Namibia. Unlike many sharks it is highly specialised on cephalopods: it hunts mainly squid and octopus, supplemented with small fish. It is viviparous, with a small litter of young. Because it is taken as bycatch and traded as dried-salted or smoked meat, it has declined sharply and is assessed as Endangered (EN).
