Pacific bluefin tuna — size comparison — facts and sources
The Pacific bluefin tuna has a powerful streamlined body and crescent-shaped tail suited to long journeys. It lives chiefly in the North Pacific. Some juveniles cross from western breeding areas towards North American coasts.
It hunts fish, squid and crustaceans. Retaining heat generated by muscles allows their temperature to remain above that of surrounding water. This supports active swimming and feeding in cooler waters encountered during extensive ocean migrations.
