Description

Richardson's moray is a small moray eel (Muraenidae) from the Indo-West Pacific. The species has an eel-shaped, scaleless body with needle-sharp teeth; the dorsal, caudal and anal fins form a continuous fringe and pelvic and pectoral fins are absent. It inhabits shallow lagoons and seaward reefs, where it often shelters under large, loose pieces of dead coral. At night it hunts small fishes and crustaceans. The sharp teeth can give a bite when handled; otherwise the fish is not aggressive.
