Scarface Blenny

Cirripectes vanderbilti

The Scarface Blenny, Cirripectes vanderbilti, is a reef-associated fish native to the Hawaiian and Johnston islands in the eastern central Pacific. Reaching a length of up to 10 cm, this species is distinguished by its dark brown body, which can sometimes appear pale brown or white. It features distinctive dark red to orange streaks on its head, extending from the snout and surrounding the eye. The dorsal fin is marked by yellowish-brown rays, while the caudal fin shows a mix of yellowish and dark brown rays. Due to its similar appearance, it is often mistaken for Cirripectes variolosus. Scarface Blennies are found in shallow waters, preferring rocky shores and coral reefs at depths of 1 to 10 meters. They thrive in tropical waters between 25°N and 15°N. As benthic dwellers, they are commonly seen on coral and rocky surfaces, where they primarily consume benthic algae and detritus. The species reproduces through oviparous means, with eggs that are adhesive and attach to substrates using a filamentous base. Divers may encounter the Scarface Blenny as it feeds on algae, displaying its unique coloration and behavior. This species poses no threat to humans and is classified as Least Concern on the IUCN Red List.
