Tuna are active, agile predators with sleek, streamlined bodies and are among the fastest-swimming pelagic fishes; yellowfin tuna can reach speeds up to 75 km/h (47 mph). Tuna, opah, and certain mackerel sharks are among the few fishes capable of maintaining a body temperature higher than the surrounding water. Found in warm seas, tuna are extensively commercially fished for food and are popular as bluewater game fish. Overfishing has put some tuna species, such as southern bluefin tuna, at risk of extinction.

Some tuna species have been driven toward extinction risk due to extensive commercial fishing and overfishing.

Pelagic, active and agile predator; among the fastest-swimming open-ocean fishes, capable of short bursts at high speed.

The strongest linked planning options currently surface around destinations such as Ari Atoll, Ibiza and Formentera, North Male Atoll and countries such as Maldives, Spain, Egypt for divers building trips around tunas.
