Description

The porbeagle is a stout, powerful mackerel shark of the family Lamnidae reaching about 3.5 metres. The torpedo-shaped body is blue-grey above and white below, with a pointed snout, large black eyes and a crescent tail with a keeled tail base; a conspicuous white patch sits at the rear of the first dorsal fin. Like related mackerel sharks it is partly warm-blooded, so it stays fast and active even in cold water. The species lives in the cool North Atlantic and the southern hemisphere and hunts schooling fish such as mackerel and herring, and squid. It grows slowly and bears few young; through heavy fishing it is assessed as Vulnerable (VU), and in the north-eastern Atlantic even Critically Endangered.
