Description

"The Almaco jack has a less elongated, more flattened body than most jack species. Their dorsal fin and anal fins are elongated, and their outer edges have a definite sickle shape. The first rays of the Almaco dorsal fin's longest parts are nearly twice as long as the dorsal spines, also different from other jacks. Almaco jacks are generally dusky-colored with faint amber or olive stripes down their sides. Their upper bodies and lower fins are usually dark brown or dark blue-green. The belly is much lighter and appears brassy or lavender. The nuchal bar and most of the fins is dark on adults. Exceptions are the pelvic fins which are white on the ventral sides."
