Bluestriped fangblenny (Plagiotremus rhinorhynchos) peeking out of its hole. This blenny inhabits lagoons and reefs of the Indo-Pacific region. It feeds on the skin and scales of other fish in short, quick attacks. It has been suggested that it mimics the blue streak cleaner wrasse to fool fish waiting to be cleaned. Photographed off Lankayan Island, Sabah, Malaysia, Borneo.
