The Spotted Snake Eel has dark spots on a cream-coloured background. The arrangement of spots changes as a fish grows. Juveniles under 25cm in length have one row of spots on the upper sides. Fish between 30cm and 50cm in length (such as that in the images) have spots along the midline alternating with spots on the upper sides. Fishes over 50cm in length have two or three rows of spots on the upper sides of the body and several rows of smaller spots along the lower surface.
This species grows to 1m in length.
The Spotted Snake Eel occurs on sandy coastal reefs where it burrows in the substrate. It is sometimes seen swimming in the open over sand or weedy areas.
It is found in marine tropical waters of the Indo-West Pacific.
In Australia it is recorded from the offshore reefs of north-western Western Australia and the northern Great Barrier Reef south to the central coast of New South Wales.
