Summary:
A moray with a bold pattern of alternating black and white to pale yellow bars, the black bars being about twice the width of the white bars. Some black bars may completely encircle the body, and some may contain small white saddles. Adults usually have the dark bars notched dorsally by a narrow white to yellow bar or slit.

Distribution

Low Isles to Hervey Bay, Queensland; also the Lord Howe Province and Norfolk Island in the Tasman Sea. Elsewhere the species occurs in the tropical, west Pacific. Inhabits inshore sandy areas.

Similar Species

The Saddled Snake Eel, Leiuranus semicinctus, has evenly-spaced dark saddles along the body, vs L. versicolor having alternating black and white to pale yellow bars, with the black bars being about twice the width of the white bars (some bars completely encircle the body, and some may contain small white saddles).

Etymology

The specific name is from the Latin versicolor (= variegated, variously coloured) in reference to the 27 purplish-brown rings, which are further divided: "The body is varied by 27 purplish-brown rings, considerably broader than the area between them; most of the rings are further divided more or less completely by narrower white lines or imperfect circles" (Richardson 1849).
