Looks very similar to the moray eel my brother-in-law caught while fishing off the pier in Bodrum. Not quite what he was expecting to catch. Putting it back in the water was as frightening as its teeth.
beauty - Blue Moray Eel - (Anguilliformes) Most eels are predators. The term "eel" is also used for some other similarly shaped fish, such as electric eels and spiny eels, but these are not members of the Anguilliformes order.
