Description

The dark moray is a moray (Muraenidae) from the eastern Atlantic, off West Africa, and adjacent brackish water. The species grows to about 1 metre and has an elongate, snake-shaped, scaleless, uniformly dark-brown body. As a nocturnal predator it hides by day in crevices and holes, with only the head showing, and seizes fish and crustaceans at night. It bites fiercely when disturbed; handle with care.
