Striped Poison-fang Blenny Mimic Petroscirtes breviceps occurs in the tropical Indo-West Pacific from East Africa to Papua New Guinea, north to southern Japan, south to New Caledonia in a depth range from 1-15m usually to 10m, max. length 11cm. \nAdults inhabit coastal reefs and estuaries in sandy and weedy areas among clumps of Sargassum or other seaweeds. They also take shelter and nests inside small-necked bottles and abandoned worm tubes or shells. \nThey feed on small crustaceans, diatoms, and perhaps other plant material associated with such clumps. They use their fangs defensively and will not hesitate to bite if handled, thus, species of this genus are avoided by predators. \nThese specimen live at 5m depth on a mooring line of a buoy that marks an outer reef. The photo was taken in the late afternoon when it was almost dark already. \nTriton Bay, Kaimana Regency, Indonesia, 3°56'19.752 S 134°7'15.198 E at 5m depth
