Where do bluefin tuna live? Bluefin tuna live mainly in the North Atlantic pelagic ecosystem and its adjacent seas, especially in the Mediterranean Sea. Geographically, their population is distributed throughout the North Atlantic, from Ecuador to Norway and from the Black Sea to Mexico.
Tuna is able to change the position of its dorsal and pectoral fins to reduce drag and accelerate the swimming speed. Tuna can swim near the surface or can dive to the depth of 3000 feet while it searches for food. Tuna is a carnivore. It feeds on different types of fish (mackerel, herring, hakeâ¦), squids and crustaceans. Unlike other fish, tuna is able to increase and maintain the body temperature few degrees above the temperature of surrounding water.
