Black markings fade with increase size, until when adult, 40–50 cm SL, where most dark spots on body are faint or absent (vs. head, mid and upper body tan with a series of irregular darker brown bands radiating from eye, along body and curving up to dorsal fin. Bands may be broken and appear as elongate spots) and fins yellowish; dorsal-fin margin brownish yellow to orange; soft dorsal, anal, and caudal fins blackish distally with a bluish white edge (vs. fins unmarked, hyaline yellow).
