Summary:
A dark brown to black snake blenny with a broad pale stripe running along the back from above the eye to the tail base, largish white spots along the midsides, the head mottled blackish head anteriorly, reddish brown posteriorly, with creamy lips and underside, creamy-white dorsal and anal fins, and a brown caudal fin with an irregular pale margin.
Clark's Snake Blenny has a prominent lower lip that is quite distinctive among snakeblennies, and easily distinguishes it from similar species.
