Body long and thin, thread-like, tangles easily, up to 12 cm long at rest, but can stretch up to 50 cm. Body width varies from 0.1 mm posteriorly to 0.7 mm in the head region. Head dorso-ventrally flattened; the rest of the body cylindrical in cross-section. Most of the time the worm remains loosely and irregularly tangled and coiled. The head contracts linearly when disturbed. Background color from very pale yellow to salmon color or deep pinkish orange (Fig.

Ocelli are proportionally much larger than in other species of the genus, resemble those of cratenemertids and reptant polystiliferans, reddish brown in color, arranged in four rows (two on each side of head, almost directly on top of each other). Eyes of the more lateral/ventral rows are larger than the eyes in the medial/dorsal rows (Fig.
