Description

The goldentail moray is a moray eel of the family Muraenidae from the western Atlantic and Caribbean. The species grows to about 70 cm and has an elongate, snake-like body that is dark brown and densely studded with small yellow spots, with a yellowish tail tip to which the name refers. It is a solitary, bottom-dwelling species of coral reefs and rocky shores, usually to a few tens of metres deep. As a nocturnal predator it hunts small fishes and crustaceans, which it tracks down in crevices and holes. With its powerful jaws and sharp teeth it can give a nasty bite; be careful.
