Chiridotidae is a family of sea cucumbers.

Description

Members of this family have 10, 12, or 18 pelto-digitate tentacles (bearing 3-10 digits on each side). They lack podia, radial canals and respiratory tree.

The soft body wall is supported by ossicles which are generally wheel-shaped with six spokes.[1] Some species have hook-shaped or rod-shaped ossicles or spiny sigmoid bodies.[2]
