A bar of lighter color along the head between the eyes and a narrow horizontal dark stripe from the snout to the gill cover separating the darker dorsal pigment from the paler lower surface. Occasionally a variable row of white spots along the side of the body. Distinguished from other clingfish by its distinctive body form (robust and tapers abruptly behind the dorsal and anal fins).
