Yellowfin (Thunnus Albacares) 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 non-specific. In the Eastern Pacific, schools are often associated with dolphin pods, which is not common elsewhere.
