Cheilopogon exsiliens

Unique Characteristics: Pectoral fins very long, reaching beyond anal-fin base to or almost to caudal-fin base. Pectoral branch of lateral line absent. Pelvic fins long, reaching well beyond anal-fin origin, inserted nearer to anal-fin origin than pectoral-fin insertion. Origin of anal fin 3 soft rays or more behind origin of dorsal fin. Dorsal fin 2-5 soft rays more than anal fin. Only the first pectoral-fin ray unbranched. Pelvic fins inserted much nearer to posterior head margin than origin of lower caudal-fin lobe. Both jaws of equal length, or lower jaw a little longer than upper jaw. Pectoral fins more densely pigmented, usually with paler transverse strip or basal triangle. Dorsal fin moderately high (longest soft ray usually less than 10 times in standard length), bearing a prominent black spot. Palatine teeth present; jaw teeth noticeable (conspicuous to the touch). Predorsal scales 24-29. Pectoral fins black with a definite pale crossband. Lower caudal-fin lobe obviously darker than upper lobe. Juveniles with moderately long, paired, flat chin barbels, their length more than 2.5 times in standard length.
