Mot deep bodied, greatest depth 16.6% (TL), belly gently rounded in mature individuals. Head moderately long, its length 22.8% (TL); eye small in adults, 17.6% of head length, but larger in young 7.6 cm long, when 25.2% of head length; snout long, 33.1% of head length of adults; interorbital width 29.6% of head length; mouth large, extending back to below anterior margin of eye. All fins clear. Pelvic axillary process usually a ridge. Peritoneum present. Nuptial tubercles fine, on head and back, on pectoral and pelvic fins and sometimes on the caudal fin. Dark green or green-brown dorsally becoming silvery white or cream ventrally. The lower fins of the males become yellow or yellow-orange during spawning period (Ref. 1998). Dorsal fin usually with 9 rays; anal fin with 8 rays; 48-72, usually 51-62, scales on back from head to dorsal fin; 64-79, usually 66-75, scales on lateral line; and 12-20 scales above lateral line (Ref. 86798). |
