The Porbeagle shark, Lamna nasus, is found in the western Atlantic from Canada to New Jersey in the USA, in the eastern Atlantic, the Porbeagle shark is found around Iceland and in the western Barents Sea to South Africa, as well as the Mediterranean sea. The Northeast Atlantic population is listed as Vulnerable on the IUCN (World Conservation Union) Red List of Threatened Species.
The Porbeagle lives mainly in the continental shelf as well as open water ocean basins wher the water temperature tends to be cooler, but has occasionally been seen in inshore waters. They prefer cooler water between 1-18°C. There have however been sightings of the
Porbeagle Shark
in waters up to 23°C and at depths of up to 715m.
The Porbeagle shark (Lamna nasus),
also known as Blue dog, Beaumaris shark in the UK, and Mackerel shark can grow up to 3.7 m (only normally between 1.6 2.0m in British waters) in length, weigh up to 230 kg ( see record above) and are thought to live for up to 30 years. The shark is closely related to the Great White shark and the Mako. The Porbeagle shark
is a large shark with a long pointed nose, large black eyes, and small, smooth, narrow teeth. The upper body (dorsal) surface varies from blue through to dark grey whilst the underside is usually white. The Porbeagle has a secondary longtitudial keel on either side of the tail which is not present on a Mako. This aids with identification.
As with all sharks in this family, the Porbeagle shark has the ability to maintain its body temperature above ambient water temperature. This trait is more common with fast swimming fish like tuna. This ability helps the Porbeagle adapt to the cold waters it inhabits and facilitates its fast swimming.
The Porbeagle shark, Lamna nasus, feeds fish like: Pollack, Cod, Ling, Coalfish, Bass, Hake, Mackerel and Herring. They also prey on other sharks and squid.
