Moray eels

Muraenidae

The reef's resident dragons — morays peek from holes with jaws rhythmically opening and closing (they're breathing, not threatening you). Cleaning stations are the best place to watch them fully emerge and hold still.

Dark brown body densely patterned with yellow speckles and a wide, gaping mouth. The classic Mediterranean moray, often seen with mouth rhythmically opening for breathing.

Peers out from rocky holes with its mouth agape — looks threatening but is just breathing. Keep hands out of crevices as bites are defensive.
