Coloration.—Basal color (in preservation) variable, ranging from tan to dark
brown or black; a series of 4-7 black rectangular blotches centered between the
upper 'lateral line and anterior extension of the lower lateral line (Fig. 1), the first
typically originating above midpoint of pectoral fin and the last under the posterior
soft dorsal. Blotches often overlie fainter crossbars, most conspicuous in subadults
but frequently obscured by dark basal coloration in adult males. Caudal
spot, centered above lower lateral line at peduncle base, present in subadults,
but often faint or lacking in dark-colored adults. Adults also occasionally develop
diffuse black speckling over the flanks and lighter, irregular spotting on the unpaired
fins. Paired fins dusky or hyaline.
