Key identification features
- Classic fusiform, torpedo-shaped tuna body built for sustained high-speed swimming
- Back is deep blue-black, contrasting sharply with a silvery-white belly and flanks
- Extremely long pectoral fins are the single best field mark, reaching back well past the second dorsal fin and sometimes past the start of the anal fin
- Tail has a distinctive narrow white trailing edge
- Small yellow finlets run along the back and belly toward the tail
Common look-alikes
- Yellowfin tuna: pectoral fins are much shorter and do not extend far past the first dorsal fin, and it shows bright yellow finlets and a yellow lateral stripe
- Bigeye tuna: has noticeably shorter pectoral fins than albacore, a larger eye, and lacks the white-edged tail
- Bluefin tuna: shorter, more rounded pectoral fins and a stockier body overall
Where you'll see one
Albacore are highly migratory and found in temperate to subtropical waters throughout the world's oceans, typically well offshore in open water from the surface down into cooler subsurface layers.
Frequently asked questions
What's the fastest way to tell an albacore from a yellowfin tuna?
Check the pectoral fins - albacore's are dramatically long, reaching well past the second dorsal fin, while yellowfin's are much shorter and don't extend nearly as far back.
How do I distinguish albacore from bigeye tuna?
Albacore have much longer pectoral fins and a distinctive white trailing edge on the tail, while bigeye tuna have shorter pectorals and a proportionally larger eye.
