Blackfin tuna ("Thunnus atlanticus") is the smallest tuna species in the "Thunnus" genus, generally growing to a maximum of 100cm (39 inches) in length and weighing 21kg (46 lbs). Blackfin have football shaped bodies, black backs with a slight yellow on the finlets, and have yellow on the sides of their body. Blackfin are only found in the western Atlantic from Cape Cod to Brazil.

This tuna does not consume as much fish in its diet than other tunas and will actually eat the tiny larvae of stomatopods (king shrimp or mantis shrimp), true shrimp, and crabs, as well as fish larvae. It does, of course, also eat juvenile and adult fish and squid. They are a short-lived, fast-growing species; a 5 year old fish would be considered old. They reach sexual maturity at two years old and spawn in the open sea during the summer. Blackfin tuna are a warmer-water fish, preferring water temperatures over 68°F (20°C). What they lack in size, they make up for in numbers and willingness to bite.
