Albacore Albacore

Albacore (Thunnus alalunga)

Also known as: Long-finned Tunny, Longfin Tuna

A member of the tuna and mackerel family, the albacore has long pectoral fins that reach to a point beyond the anal fin. Juvenile albacore might have shorter pectoral fins than similar-sized yellowfin tuna or bigeye tuna. The deepest part of the albacore’s body is near the second dorsal fin, rather than near the middle of the first dorsal fin as found in other tunas.
