Moray eel

This is a close-up of a moray eel of the Costa Brava, Spain.  Notice the detail of its face, the texture of its skin and check out those teeth which can be barely made out and which you don´t want to feel.  Morays in different parts of the world vary in their personalities, ranging from "friendly and playful" to dangerous and aggressive.  If you´re not sure, treat all morays as potentially dangerous and just take their picture.
