King mackerel
The king mackerel or kingfish (''Scomberomorus cavalla'') is a migratory species of mackerel of the western Atlantic Ocean and Gulf of Mexico. It is an important species to both the commercial and recreational fishing industries.
==Description==
The king mackerel is a medium-sized fish, typically encountered from five to , but is known to exceed . The entire body is covered with very small, hardly visible, loosely attached scales. The first (spiny) dorsal fin is entirely colorless and is normally folded back into a body groove, as are the pelvic fins. The lateral line starts high on the shoulder, dips abruptly at mid-body and then continues as a wavy horizontal line to the tail. Coloration is olive on the back, fading to silver with a rosy iridescence on the sides, fading to white on the belly. Fish under show yellowish-brown spots on the flanks, somewhat smaller than the spots of the Atlantic Spanish mackerel, ''Scomberomorus maculatus''. Its cutting-edged teeth are large, uniform, closely spaced and flattened from side to side. These teeth look very similar to those of the bluefish, ''Pomatomus saltatrix''.
