Bigeye tuna are generally the size of yellowfin, and smaller than bluefin. They are long and streamlined, have dark metallic blue on their backs and upper sides, and are nearly white on their lower sides and belly. They can live as long as 15 years. Bigeye are found in the subtropical and tropical areas of the Atlantic (but not in the Mediterranean), Indian and Pacific Oceans.
