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.

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
Orangespotted goby depth. The goby and its host shrimps interact closely and the goby is dependent on its hosts' burrow for cover. The goby acts as a sentinel, watching for danger from the entrance of the burrow. The diet of the orangespotted goby consists mainly of small gastropods, decapods, ostracods and isopods.
