The Yellowfin tuna (Thunnus albacares) is a large predatory fish found worldwide in tropical and subtropical waters, minus the Mediterranean. Just like Dori from Finding Nemo, the yellowfin tuna is built for speeeed. Also, endurance.
The yellowfin gets it's name from the yellow tiny fins (finlets) that run down the top and bottom of the fish. Yellowfin are schooling fish, however they prefer to school with fish of the same size, rather and fish of the same species. They are often found schooling with skipjack tuna and bigeye tuna and even porpoises and dolphins.
Like other tuna species across the globe, yellowfin are facing decline. Recent reductions in catch numbers have led to their reclassification by the IUCN as Near Threatened.
