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
Sphinx blenny Sphinx blenny The Sphinx blenny ("Aidablennius sphynx") is a species of combtooth blenny, and the only species in the genus "Aidablennius". It was described by Achille Valenciennes in 1836, originally under the genus "Blennius", and was later reassigned under ""Aidablennius"" by Gilbert Percy Whitley in 1947. It is a subtropical blenny known from Morocco, in the eastern Atlantic Ocean, and also from the Mediterranean and Black Seas. Sphinx blennies inhabit shallow, rocky waters in the littoral zone, with sunlight exposure. They feed primarily on benthic algae, weeds and invertebrates. Sphinx blennies can measure up to long in total length. In
