Black-faced blenny Black-faced blenny The black-faced blenny ("Tripterygion delaisi") is a small benthic fish from the family Tripterygiidae (triplefin-blennies). It occurs at depths of -3 to -40 m and lives on the substrate under large rocks, cliffs or other overhangs. Like all triplefin-blennies, "T. delaisi" has three dorsal fins and can hence easily be distinguished from members of the families Blenniidae (1 dorsal fin) and Gobiidae (2 dorsal fins) that have a similar live-style and general appearance. It has a peaked head and short tentacles above the eyes.⁠ The common name yellow black-faced blenny derives from the colouration of territorial males during
Kirk's blenny maximum total length of 11 centimetres (4.33 inches), and feed primarily off of benthic algae. Kirk's blenny The Kirk's blenny ("Alticus kirkii") is a species of combtooth blenny (family Blenniidae) in the genus "Alticus". It was described by A. Günther in 1964, originally as a member of the genus "Salarias". It is a tropical blenny which is known from the Red Sea, Mozambique, Réunion, the Persian Gulf, and India, in the Indian ocean. Kirk's blennies inhabit waters near the shore, and often spend time out of the water. They are able to breathe air when on land. They are oviparous,
