Max. weight reported: 5-191.0 kg

Color: Body covered with large dark spots on some of its scales that produce a series of dark bands interspersed with narrower white bands along the length of its body. A distinctive pair of lines runs through the eye, the lines becoming more distinct posterior to the eye.

Adults of this species develop thick lips and a prominent bulbous hump on the forehead. Body slightly longer than deep; head contained 3.1 times in total length; eye diameter 9.7 times in head length, interorbital distance double the eye diameter; dorsal fin base 2.6 times in total length. Dorsal fin with IX spines and 10 rays; the posterior rays longer than spinous portion; pectoral fin with 12 fin rays; pelvic fin with I spine and 5 rays; anal fin with III spines and 8 rays and caudal fin with 13 rays. Lips very thick, fleshy and projecting; mouth with two sharp teeth on upper jaw and two smaller ones on lower jaw; numerous smaller white teeth on both the jaws. As the fish passes through different stages, the forehead becomes increasingly enlarged and lips become fleshier and body color changes to pale green with elongate dark spots tending to form bars.
