Myriotrochidae is a family of sea cucumbers.

Description and characteristics

[edit]

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]
