Shorthead Fangblenny yawning

On today’s morning dive i was lucky enough to capture this yawning Shorthead Fangbleny (Petroscirtes breviceps). The yawn makes his long curved canine teeth visible, which it uses for defense. Shorthead Fanblennies are very common in North Sulawesi and like hiding in bottlenecks – so obviously there are many of them in Lembeh Strait. They grow to 13 cm in size and are very easy to photograph – and if you are lucky (and patient) enough you can even see (or photograph) them yawning.
