Yellowfin tuna is a species of tuna used for human food. It is found offshore in tropical and subtropical waters around the world, although not found in the Mediterranean region. According to some reports, it can be as long as 239 cm (94 inches) and weighs up to 200 kg (440 pounds).
The second and anal dorsal fin are bright yellow, so it has this name. These fins as well as pectoral fins are very long. Its body is dark green metallic, changed to silver on the abdomen. It also has about 20 vertical bars.
Yellowfin tuna tend to swim with other types of fish of the same size, including other tuna as well as other larger fish such as dolphins, whales or whale shark. Yellowfin tuna eat other small fish, crustaceans or squid.
People caught yellowfin tuna with fin nets, as well as with fishing rods and fishing lines. This fish is sold mainly in frozen or canned form, but also very popular in the form of sashimi – a type of Japanese fish salad.
