How to tell them apart

Albacore

Pectoral fins absurdly long, sweeping back past the anal fin; deep-blue back, chalk belly.

Bigeye Tuna

Stockier than yellowfin, oversized eye, duskier fins; honest answer — hard to call, measure and check.

Bigeye tuna, next to albacore: stockier with a bigger eye; pectorals never reach that far.
