Petroscirtes fallax (Smith-Vaniz, 1976)
Petroscirtes fallax, also known as the Yellow Sabretooth Blenny, has an elongate body and a blunt downward-pointing snout. The species is endemic to Australia, it occurs in coral reefs and sheltered coastal bays and estuaries from northern Queensland to southern New South Wales.
The Yellow Sabretooth Blenny has a single long-based dorsal fin. The mouth can be opened very wide to expose a pair of large curved canines at the front of the lower jaw. The species is yellow above and white below. There are three dark stripes on the head and body.
The species may be a mimic of the venomous Lined Fangblenny Meiacanthus lineatus.
