In the vastness of the oceans, the tuna family shines in a unique light. The tuna belongs to the mackerel family of the order Perciformes, which contains nine fascinating species.

The albacore tuna is found in temperate and tropical waters of the world's oceans, including the Mediterranean Sea, in a range of 0 - 600 meters. Its pectoral fins are extremely long, as if it were a graceful dancer in the ocean, reaching a maximum fork length of 127 centimeters.

The yellowfin tuna, which is active in tropical and subtropical waters around the world, is only rarely found in the Mediterranean. It is found at depths of 0 - 250 meters and is often larger than 200 centimeters in length, with its bright yellow dorsal and anal fins resembling the golden flag of the ocean.

Blackfin tuna, distributed in the western Atlantic area, active at a depth of 0-200 meters, body length is usually about 100 centimeters, dorsal fins are dull, the ventral fins are usually gray, and the silvery scales flash in the sunlight, like a silver lightning in the ocean.

The Southern Bluefin Tuna is found throughout the Southern Ocean south of 30°S latitude, with a range of 50-2743 meters and a maximum fork length of 225 centimeters, making it a mystery in the deep Southern Ocean.

The Pacific Bluefin Tuna, swimming in the embrace of the Pacific and Indian Oceans, with a range of 0 - 550 meters and a maximum fork length of 300 cm, is an elegant hunter in the ocean.

The Atlantic bluefin tuna, which is widely distributed in the Atlantic, Pacific and Mediterranean Oceans, has a range of 0 - 1000 meters and a body length of more than 300 centimeters, and as the largest tuna, it has dark blue fins and a silvery grey dorsal to abdominal area, which makes it look like a king.
