Petroscirtes breviceps

The shorthead fangblenny (Petroscirtes breviceps) is a small, striped blenny that often shelters in bottles, cans and empty shells on muck sites. It usually shows dark stripes along a pale body, a pattern that mimics the venomous striped poison-fang blenny.

Reaching around 10 cm, it lives in seagrass, algae and sandy areas. It has a pair of large fangs in its lower jaw and feeds on small invertebrates and algae. Males guard eggs laid inside their chosen shelter.

The shorthead fangblenny occurs across the Indo-West Pacific, including the Philippines, where it is a familiar sight peering out of discarded bottles and shells on sandy slopes.
