Description

The Atlantic bluefin tuna is a huge, torpedo-shaped predator of the family Scombridae that can reach about 4.5 metres and hundreds of kilograms. The streamlined body is metallic blue above and silvery-white below, with a sickle-shaped tail and a row of small separate finlets before the tail. Like its relatives the species is partly warm-blooded, enabling its powerful muscles and high speed; it is among the fastest fish. The species lives in the Atlantic and the Mediterranean and makes enormous migrations, returning to warm seas to spawn. It hunts herring-like fish, mackerel and squid in schools. The Atlantic bluefin is highly prized for the sushi market; after stricter management the eastern population recovered and the species is again assessed as Least Concern (LC).
