Thunnus alalunga, commonly known as the albacore tuna, is a migratory fish found in temperate and tropical oceans worldwide. It is known for its long pectoral fins, streamlined body, and silvery coloration. Albacore tuna are fast swimmers and form schools, playing a crucial role in marine food webs.

Thunnus alalunga, commonly known as Albacore, is native to the temperate and tropical oceans of the world. Its geographical distribution includes the Atlantic Ocean, Pacific Ocean, and Indian Ocean, as well as the Mediterranean Sea. It is found in both the northern and southern hemispheres, with notable populations in regions such as the North Atlantic, South Pacific, and waters surrounding Japan and New Zealand.

Albacore tuna typically inhabit open ocean environments, preferring epipelagic waters that are well-oxygenated and within the temperature range of 15 to 20 degrees Celsius. They are often found at depths between 0 and 600 meters, although they may dive deeper in search of food.

As a highly migratory species, Albacore tuna occupy a niche as mid-level predators in the oceanic food web. They primarily feed on small fish, squid, and crustaceans, utilizing their speed and agility to capture prey. Albacore play a crucial role in marine ecosystems, contributing to the regulation of prey species and serving as prey for larger predators such as sharks and marine mammals.
