Atlantic bluefin tuna

The Atlantic bluefin tuna (Thunnus thynnus) lives in the Atlantic Ocean, the Mediterranean and the Black Sea. It moves in schools and makes important migrations to feed and reproduce. Although it tends to live in surface waters, it can dive to depths of up to 1000 m. This voracious and fast predator (it is capable of speeds of over 100 km per hour) feeds on fish, squid and pelagic crustaceans (living in open water). A record-breaking fish, it can live for 40 years or more, reach 3 m in length and weigh 600 kg! Located at the top of the marine food chain, its predators are the killer whale, the great white shark … and Man!
