Skipjack Tuna (Katsuwonus pelamis) are dark blue on the back and silvery on the belly. They are easily identified by the 3 to 6 longitudinal bands on their lower sides which run from tail towards the head but taper out before reaching the head. These tuna have fine, slender teeth, a strong keel on the caudal fin base between two small keels. The second dorsal fin is barely separated from the first.

Skipjack tuna like most tunas are a schooling fish. They feed on smaller fish and squid. Big skipjacks will even eat little skipjacks.

Key Notes and Tips:
     *Distinguishing marking on the belly.
     *Big skipjacks will even eat little skipjacks.
     *Range throughout all the warm oceans of the world.
