Moray eels are elongated, snake-like fish with large mouths and sharp teeth. They can grow over 3 meters long, though most species are smaller. Their scaleless, often patterned skin provides excellent camouflage among rocks and corals. Despite their fearsome look, they are generally shy creatures.
Morays are mostly nocturnal predators, ambushing fish, octopus, and crustaceans. They often keep their mouths open while resting, not in aggression, but to pump water through their gills. Some species hunt cooperatively with groupers.
Divers often see morays poking their heads from reef holes or swimming freely at night. While generally harmless, they should not be provoked or fed, as bites can be severe.
Most species are Least Concern, though some face pressure from the aquarium trade and habitat loss.
