Morphology | Morphometrics
soft rays: 7;
Vertebrae: 26. This species is distinguished by the following characters: D VI + I,11; A I,7; pectoral rays 13-14 (usually 13); segmented caudal rays 15-16 (usually 15); body or head scaleless; cephalic sensory pores absent; elongated body, depth at pelvic-fin origin 6.1-6.4 in SL, and compressed, the width 1.5-1.75 in depth; strongly convex snout; tricuspid teeth; gill opening directly preceding and equal in length to pectoral fin base; pelvic fins united, reaching about half distance to origin of anal fin; well developed pelvic frenum; broadly rounded caudal fin, longer than head length; body in both sexes white with 9 or 10 (usually 9) dark brown bars, broader than pale interspaces, those below dorsal fins continuing narrowly into fins; a dark bar on postorbital head (Ref. 82648).
Occurs in the highest pools of the intertidal and some in the splash zone above high tide, at pools no deeper than 10 cm (probably with extraordinary tolerance to extremes of temperature and salinity (Ref. 82648).
