The porbeagle shark (*Lamna nasus*) is a species of mackerel shark in the family Lamnidae. It lives in cold and temperate waters of the North Atlantic and parts of the Southern Hemisphere, and is known for its streamlined body, seasonal migrations, and ability to keep its body warmer than the surrounding water.

Description

The porbeagle is a large, streamlined shark with a pointed snout, crescent tail, and dark upper body with a pale underside. It is built for speed and is often described as resembling a smaller white shark.

Distribution and habitat

This species occurs in cold and temperate waters, especially in the North Atlantic, and also in parts of the Southern Hemisphere. It is mainly a coastal and oceanic shark and is known to move seasonally between inshore and deeper waters.

Biology and diet

Porbeagles can keep their body temperature higher than the surrounding water, which helps them remain active in colder seas. They feed on fish and cephalopods and are generally pelagic, though they also use coastal waters.

Conservation

The porbeagle has been heavily affected by fishing pressure, including targeted capture and bycatch. Global conservation assessments list it as Vulnerable, while some regional populations are considered more threatened.
