About Chestnut Blenny

The Chestnut Blenny is a small, elongated fish with a chestnut-brown to reddish-brown coloration throughout the body. It has a blunt head, small scales, and a continuous dorsal fin running along the back. The body tapers toward the tail, and it features small cirri (tentacle-like structures) above the eyes—a characteristic feature of the Cirripectes genus.
