Description
The species in the genus Caranx are all moderately large to very large fishes, growing from around 50 cm in length to a known maximum length of 1.7 m and 80 kg in weight; a size which is only achieved by the giant trevally, Caranx ignobilis, the largest species of Caranx. In their general body profile, they are similar to a number of other jack genera, having a deep, compressed body with a dorsal profile more convex than the ventral. The dorsal fin is in two parts, the first consisting of 8 spines and the second of one spine and between 16 and 25 soft rays. The anal fin has one or two detached anterior spines, with 1 spine and between 14 and 19 soft rays. The caudal fin is strongly forked. All species have moderate to very strong scutes on the posterior section of their lateral lines. All members of Caranx are all generally silver to grey in colour, with shades of blue or green dorsally, while some species have coloured spots on their flanks. Fin colours range from hyaline to yellow, blue and black.
The specific characteristics that distinguish the genus relate to specific anatomical details, with these being a gill raker count between 20 and 31 on the first gill arch, 2 to 4 canines anteriorly positioned in each jaw, and dorsal and anal rays which are never produced into filaments as seen in genera such as Alectis and Carangoides.

Famous quotes containing the word description:
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
