L. gobio is a benthic organism with a wide range, taking up residence in a number of coastal environments from Florida to Brazil.

[2] On either side of the head are two or more heavily branched cirri, which are tentacle-like structures lacking features of a traditional tentacle.

[3] The palehead blenny lacks an opercular ocellus, which is a colored spot on the head resembling an eye.

[3] This feature is common of shorefishes in the greater Caribbean area, so this is one of the markers that Gobioclinus gobio is a non-endemic species.

[3] The outer row consists of large teeth resembling canines or incisors in the upper jaw.

[2] The peritoneum, which is a membrane lining the fish’s body, is white with large pigment cells called melanophores.

Gobioclinus gobio is a marine organism that inhabitants subtropical reefs within depths of 0–15 meters, on rocky shores with heavy vegetation, including algal mats and seagrass beds.

[3] It prefers reef habitats with coral and limestone formations, and soft substrates such as sand and gravel.

[2] Gobioclinus gobio populates the Western Atlantic coast of Latin America and around the West Indies, from Mexico to the islands of the Lesser Antilles.

[3] The blenny’s distribution likely extends to the Western coast of northern South America, as well as the Antilles island chain.

[3] Gobioclinus gobio is a carnivore known to feed on bony fishes and a number of mobile, benthic organisms including worms, crustaceans such as shrimps and crabs, gastropods, and bivalves.

[4] In order to reside unharmed among the stinging tentacles of the anemone, it has developed both physiological and behavioral adaptations, and is one of nine Caribbean reef fishes recorded to display this characteristic.

[4] The behavioral mechanism by which L. gobio acclimates to the anemone is hypothesized to be by a factor of the fish’s ability to alter its mucous coating in order to avoid stinging.
