Nocturnal and shy creatures, green morays often hide in crevices and coral. Their dorsal, caudal and tail fins are joined as one long fin down their back and up their belly. They often anchor their tails between rocks while they hide during the day. They have no scales, just a leathery skin. Eels are secretive and employ stealth as a primary hunting technique.
