Moray eels have skin that is scaleless, thick, camouflaged , and covered with protective mucus. The eyes are tiny, and this fish has very bad vision. Morays have a small, circular gill on each side of the head, well behind the mouth. The wide jaws are filled with long, sharp teeth. Camouflaged moray eels hide among rocks, coral, or eelgrass beds, waiting for prey animals to get near enough to catch them.
Morays find prey mostly by using a keen sense of smelll.
Morays have few predators. Large groupers and other moray eels sometimes prey upon morays.
