Shorthead Fangblenny

The Shorthead Fangblenny (Petroscirtes breviceps) its just a little bit poisonous, but it mimics its relatives from the genus Meiacanthus. These got an even stronger poison at their large saber teeth and are therefore avoided by most predators. P. breviceps only uses its poison for defense. It feeds mainly on algae and diatoms, which it scrapes off the substrate. The slender fish, which grows to 11 cm, likes to hide in holes, such as beer bottle necks, as it is often found in calm, sediment-rich bays.
