Island Trevally Video Stock Footage
The island trevally is a moderately large fish, growing to a maximum recorded length of 75 cm and 6.61 kg in weight. The species is quite similar to C. ferdau, although the prominent yellow spots serve as a quick identifying feature. The island trevally has a compressed oblong shaped body with the dorsal profile more convex than the ventral profile and the snout usually being slightly rounded. The dorsal fin is in two sections, the first consisting of eight spines and the second of one spine and 28 to 31 soft rays, with the lobe of the second dorsal fin being slightly falcate in younger individuals, but is always shorter than the head length.

The curved section contains 96 to 106 scales, while the straight section contains 20 to 30 scales and 21 to 28 scutes. The breast is scaleless ventrally until the origin of pelvic fins, often with a small patch of prepelvic scales. Laterally, this naked area of the breast is separated from the naked base of the pectoral fins by a moderate band of scales. The lips are notably fleshy in adults, with both jaws containing narrow bands of villiform teeth which become obsolescent with age. There are 28 to 32 gi...
