Here is Giant Moray Eel - actually only the head of Moray. Normally they hide themselves in the rocks, as their long and massive body is not safe at opened waters. Then it is siting with open mouth and hunting all that comes into (exceptof cleaners who enter and leave free). Moray has poor eyesight but an excellent sense of smell. They can reach up to 3m, then they get so huge that already doesnt have anemies. I have seen few times huge morays free swimming. Quite amazing thing, i have to say.
