Albacore Tuna

Thunnus alalunga

The albacore tuna — also called "white tuna" — is the only tuna species whose flesh is light in color, making it the basis of most canned white tuna. Found in temperate and tropical oceans worldwide, albacore are pelagic fish that follow the warm currents. Their extremely long pectoral fins are the key to their identification, giving them a distinctive look among the tuna family.
