Description

The freckleface reef-eel is a moray (Muraenidae) from coastal and reef-lagoon water of the Indo-West Pacific. The species grows to about 62 cm and has an elongate, snake-shaped, brownish, scaleless body with fine pale freckles on the head, to which it owes its name, and strongly reduced fins. As a nocturnal bottom-dweller it hides by day among stones and in crevices of shallow reefs and hunts small crustaceans and small fish at night. It bites when disturbed; handle with care.
