Description

The bluestriped fangblenny is a small, elongate blenny (Blenniidae) from the Indo-West Pacific. The species reaches about 12 cm and has a blue body with orange lateral stripes; the colour can vary greatly. It inhabits clear, coral-rich parts of lagoon and seaward reefs and shelters in empty worm tubes when alarmed. With the rearward-pointing canines in its lower jaw it darts out from ambush to snatch bits of skin, mucus and sometimes scales from passing fishes. When approached it sometimes also bites divers.
