Albacore (Thunnus alalunga)

Distinctive Characteristics Albacore can be distinguished from other tunas by a long pectoral fin that may reach to a point beyond the anal fin. The pectoral fin in juvenile albacore may be similar to that of yellowfin or bigeye. A swimbladder is present, but is poorly developed and not evident in individuals smaller than about 25-32 gill rakers on the first gill arch.

Albacore lack any stripes or spots on the lower flanks and belly. The tail fin has a thin white trailing edge. There is no yellow on the main fins, but the dorsal finlets are yellowish. The anal finlets are silvery or dusky.
