Description

The striped poison-fang blenny mimic is a blenny from the Indo-West Pacific, ranging from East Africa to Papua New Guinea, north to southern Japan. The species grows to about 11 cm and has an elongate body with a broad dark stripe from the snout through the eye to the tail. It mimics the venomous fang blennies of the genus Meiacanthus and has enlarged canine teeth in the lower jaw. It lives on coastal reefs, in estuaries and among weed, and likes to shelter in empty bottles and tubes. When handled it does not hesitate to bite with its teeth. The IUCN assesses the species as Least Concern (LC).
