Description

The brown moray is a uniformly dark-brown moray of the family Muraenidae reaching about 1 metre. The snake-like, scaleless body lacks pectoral fins and has a continuous fin fringe over back, tail and belly; the mouth is set with sharp, backward-pointing teeth. By day the moray shelters with only its head out of a rock crevice, rhythmically opening and closing its mouth to pump water over the gills. The species lives on rocky bottoms of the Mediterranean and the adjacent eastern Atlantic. At night it ambushes fish, squid and crustaceans. It is not venomous, but can bite fiercely when disturbed; its teeth cause deep wounds that readily become infected.
