What specific coloration of the fins gives the Yellowfin Tuna its common name?
Answer
Brilliant golden or bright yellow
The characteristic that defines the common name of the species is the brilliant coloration found on its fins. Specifically, the dorsal, pectoral, anal, and pelvic fins display a vivid golden or bright yellow hue in healthy, adult specimens. This distinctive feature is often cited as the quickest way for someone observing or angling for the fish to confirm its identity, distinguishing it readily from closely related tuna species.
