Description

The variable sabretooth blenny is a small blenny from the Indo-West Pacific. The species grows to about 15 cm and has an elongate, scaleless body with a variable, mottled colour pattern and a pair of large, sabre-like canines in the lower jaw. As a dweller of shallow coastal and reef water it shelters in empty shells, tubes and cavities and feeds on small benthic life and algae. It uses the large teeth mainly for defence. The fish is largely harmless to humans. The IUCN has not evaluated the species.
