Blackfin tuna have oval-shaped bodies, black backs with a slight yellow on the finlets, and yellow on the sides of their bodies. They are only found in the western Atlantic from Cape Cod to Brazil.
Blackfin tuna hunt both epipelagic (surface) and mesopelagic (deeper water) fish and squid. They also eat crustaceans such as shrimp, crabs, amphipods, stomatopods, and the larvae of decapods. They are a short-lived, fast-growing species; a 5-yr-old fish would be considered old. They reach sexual maturity at the age of two years, and spawn in the open sea during the summer. Blackfin tuna are a warmer-water fish, preferring water temperatures over 20 °C (68 °F).
