How to Identify a Yellowfin Tuna
- Dark metallic blue back, silvery-white belly, and a golden-yellow stripe down the side
- Greatly elongated, sickle-shaped (falcate) second dorsal and anal fins on larger adults
- Bright yellow finlets edged with a narrow black margin
- Lower flanks/belly often marked with alternating pale lines and rows of dots
- Pectoral fin moderately long, reaching to about the second dorsal origin (not past the anal fin as in bigeye)
Tell it apart: Long, bright-yellow sickle-shaped dorsal and anal fins plus yellow black-edged finlets distinguish yellowfin from the much smaller blackfin, which keeps short fins and dark, dusky finlets.
Easily confused with: Blackfin Tuna
