Albacore are pelagic predators, eating a wide variety of foods, including fish, crustaceans, and cephalopods. They are unique among tuna in that their primary food-source is cephalopods, with fish making up a much smaller portion of their diet. Reproduction usually occurs from November to February and is oviparous. An adult female can release over two million eggs in a single cycle. Fry (juvenile fish) generally stay near where they were spawned for about a year before moving on. Albacore form schools based on their stage in the life-cycle, but also combine with other tuna like the skipjack tuna, yellowfin tuna, and bluefin tuna. Schools of grown albacore are highly migratory.
