Black-faced blenny 2007) and "T. tripteronotum" (Risso, 1810). Besides "T. delaisi", all species are endemic to the Mediterranean Sea. The species "T. delaisi" is subdivided in two subspecies: "T. delaisi delaisi" in the Mediterranean Sea and "T. delaisi xanthosoma" in the Atlantic Ocean. The subspecies can be distinguished by their courtship behaviour: "T. delaisi delaisi" court in free water and "T. delaisi xanthosoma" stay on the ground for courtship behaviour. The speciation process is still under discussion and several hypotheses have been proposed. Black-faced blenny The black-faced blenny ("Tripterygion delaisi") is a small benthic fish from the family Tripterygiidae (triplefin-blennies). It occurs
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,
