Also known as Deep-Bodied Tunny, Albacore, or Bonite Nore in French, the Blackfin Tuna is the smallest tuna in the Thunnus genus. This fish has an oval-shaped body colored black with some faded yellow near the finlets and on the sides.

It has an eye-catching lateral band colored yellow or gold which fades upon its death. Its silvery abdomen has some vertical rows embedded with pale dots. 

Another feature that adds to the Blackfin Tuna’s beauty are the bronze reflections on its dusky dorsal finlets.
