You see this fellow coiled in the sand or in a rock or coral lair under shallow waters, waiting for something good to swim by. He's watching intently, and he's watching you, too. Uncoiled, he looks like a rather pudgy snake, but he's quite a powerful predator with speed, spines, and snapping fangs. He's sort of like a moray eel with dragonish features. I'd stay away from him if I were you.
