The Chelidonura species belong to the head shield snails. They are characterized by an essentially cylindrical and streamlined body, a broad head shield, usually with sensory cilia arranged on the anterior margin, well-developed parapodia that fold over the sides of the body to meet on the midline and elongated caudal lobes.
In Chelidonura amoena, the parapodia touch or barely overlap on the midline. The left caudal lobe is three to four times as long as the right. The ground color of the head shield snail is white, which is bordered by pale yellow edges on the head shield, parapodia and posterior shield including the tails.
The white ground color is overlaid by a fine grey or brown net of varying intensity and distribution, so that the underlying white shows through as small dots. There are a number of color variations.
The diet is thought to consist of small Acoel flatworms, just like many other members of the genus.
