Description

The xestus sabretooth blenny is a small blenny (Blenniidae) from coastal and reef-lagoon water of the western Pacific. The species grows to about 8 cm and has a slender, yellow-brown body and two large, sabre-shaped canine teeth in the lower jaw. As a bottom-dweller it shelters in empty shells, tubes and crevices of shallow water and snaps at small invertebrates. When handled it can give a painful nip with its large canines; otherwise it is harmless to humans.
