Scombridae is the family of the mackerels, tunas, and bonitos, and thus includes many of the most important and familiar food fishes. The family consists of about 55 species in 15 genera.

Scombrids have two dorsal fins, and a series of finlets between the rear dorsal fin and behind the anal fin. The caudal fin is strongly divided and ridgid, with a slender, ridged, base. The first (spiny) dorsal fin and the pelvic fins are normally retracted into body grooves. Species length varys from the 20 cm length of the island mackerel to the 458 cm recorded for the immense northern bluefin tuna.

Scombrids are generally predators of the open ocean, and capable of considerable speed.

Some members of the family, in particular the tunas, are notable for being endothermic (warm-blooded).

[edit] Classification

Jordan, Evermann and Clark (1930) divide these fishes into the four families Cybiidae, Katsuwonidae, Scombridae, and Thunnidae,<ref>David Starr Jordan, Barton Warren Evermann and H. Walton Clark (1930). Report of the Commission for 1928. U.S. Commission for Fish and Fisheries, Washington, D.C..</ref> but this article follows FishBase in placing them in the single family Scombridae.<ref>"Scombridae". FishBase. Ed. Ranier Froese and Daniel Pauly. January 2006 version. N.p.: FishBase, 2006.</ref>
