Robust body; short dorsal and anal approximately opposite one another at midbody; caudal fin rounded, symmetrical; myomeres 8-11 + 24-26 = 36; prominent dorsal, ventral, and midlateral melanophore series, becoming somewhat obscured by heavy dorsolateral pigment after about 9-10 mm; irregularly barred pattern on juveniles. Notochord flexion occurs before hatching. Pigmentation: Larvae: heavy over mid- and hindbrain; light over forebrain and on snout; light on gill cover and dentary; upper half of head becoming heavily pigmented by about 8 mm; 2 rows along dorsal margin and ventral margin of tail; 1 row along lateral midline; dorsolaterally on trunk, spreading caudad and ventrad to cover upper half by 9 mm; ventrolaterally on tail after 9 mm; on and under brain; over and under vertebral column; on caudal, dorsal, and anal fins by about 8.5 mm, on pectoral fins by 10 mm; 0-few ventrally on gut. Juvenile: heavily pigmented dorsally and dorsolaterally, lighter ventrolaterally; irregular barred pattern, mainly on tail. Sequence of fin development: caudal, pectorals, anal, dorsal, pelvics.
