What Even Is a Bonito? What Is a Skipjack? Little Tunny?
Bonito, skipjack tuna, and little tunny are all marine fish that are members of the same sub-family, called Scombrinae. Scombrinae are ray-finned, bony fishes that include four “tribes”: Mackerels, Spanish Mackerels, Bonitos, and Tunas.
All members of this sub-family (Scombrinae) have a tapered - almost bullet-shaped - muscular body that makes them fast swimmers and ferocious fighters when caught. They are all at least semi-migratory while following prey, and are fished both commercially and recreationally. They also all have two dorsal fins (one that is spiny and one that is soft) as well as having somewhere between a deeply forked and a lunate (semi-forked) tailfin.
