Yellowfin (Thunnus albacares) are found in the tropical and subtropical areas of the Atlantic, Indian, and Pacific Oceans. Yellowfin reach intermediate sizes, between albacore and bigeye. They form both free and associated schools, with adults generally forming schools of similarly sized individuals. The free-swimming schools tend to contain large individuals and are mono-specific. In the Eastern Pacific, schools are often associated with dolphin pods, which is not common elsewhere.
