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
Bucchich's goby Bucchich's goby Bucchich's goby ("Gobius bucchichi") is a species of goby native to the Eastern Mediterranean Sea and perhaps the Black Sea. It has traditionally been considered to be more widespread, but in 2016 the similar incognito goby ("G. incognitus") was described. It had been confused with the Bucchich's goby and much information formerly published for this species is now considered to actually be for the incognito goby. The Bucchich's goby prefers coastal waters with a sandy or muddy substrate with seagrass patches or tide pools at depths of from . Its diet consists of polychaete worms, amphipods, molluscs and
