Myriotrochidae is a family of sea cucumbers.
Description and characteristics
Members of this family have digitate tentacles, bearing 2-8 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 8 or more spokes.
They are abyssal sea cucumbers, and may be the deepest-living group of echinoderms : species of the genera Myriotrochus and Prototrochus (such as Prototrochus bruuni) have been identified down to 10,687 m (35,062 ft) deep.[1]
