Dorsale stekels (totaal) : 13 - 14; Dorsale zachte stralen (totaal) : 10; Anale stekels: 7; Anale zachte stralen: 9 - 10; Wervels: 23. Coloration highly variable; influenced by substrate's color and mood of the fish. Upper greenish to sandy brown, paler below. Color patterns extend to the fins. Spines slender, pungent and venomous. Preopercular angle 88°-98°; cheeks with few scales; midline of thorax without scales between pelvic ridges. Long flap of anterior nostril shortens with increasing age.
