Description

The needle-tooth moray is a moray eel (Muraenidae) from the Indo-West Pacific. The species has an eel-shaped, scaleless body with a fairly large head and needle-sharp teeth; the dorsal, caudal and anal fins are fused into a low fringe and pelvic and pectoral fins are absent. It inhabits exposed seaward reefs to about 14 m deep and shelters solitarily in crevices and holes by day, hunting small fishes and crustaceans at night. The sharp teeth can give a serious bite when handled; otherwise the fish is not aggressive.
