Tuna is a large fast-swimming fish, not a true tuna, but is closely related to the Bonitos. It has the large teeth and straight edged first Dorsal Fin characteristic of all Bonito. Appreciated as both a game fish and food fish, a large specimen can give a good struggle.
It will readily attack most fish that will fit in its mouth: Mackerels, Sardines etc.
