About Tuna

A tuna is a saltwater finfish that belongs to the tribe Thunnini, a sub-grouping of the mackerel family (Scombridae), which includes the bonito (Sardini) and mackerel (Scombrini) tribes. Thunnini comprises fifteen species across five genera, the sizes of which vary greatly, ranging from the bullet tuna (max. length: 50 cm (1.6 ft), weight: 1.8 kg (4.0 lb)) up to the Atlantic bluefin tuna (max. length: 458 cm (15.03 ft), weight: 684 kg (1,510 lb); the bluefin averages 200 cm (6.6 ft), and is believed to live for up to 50 years. Their circulatory and respiratory systems are unique among fish, enabling them to maintain a body temperature slightly higher than the surrounding water. An active and agile predator, the tuna has a sleek, streamlined body, and is among the fastest-swimming pelagic fish the yellowfin tuna, for example, is capable of speeds of up to 75 km/h (47 mph). Found in warm seas, it is extensively fished commercially and is popular as a game fish.
