Labrisomus nuchipinnis, the hairy blenny, is a species of labrisomid blenny native to the Atlantic Ocean from the coast of the Americas to the African coast. This species prefers areas that give them crevices and holes to shelter in such as areas with rock or rubble substrates, reefs or beds of seagrass. They can be found in shallow water only a few centimeters deep to a depth of 10m (30feet) though they are much rarer deeper than 5m (16feet). Carnivorous, they prey on such animals as crustaceans, gastropods, echinoderms such as urchins and brittle stars, polychaete worms and other fishes. This species can reach a length of 23cm (09inches) TL. They can also be found in the aquarium trade.
