Molpadiidae

Molpadiidae is a family of sea cucumbers, marine invertebrates with elongated bodies, leathery skins and tentacles that are found on or burrowing in the sea floor.

Description

They are relatively inactive and live in a U-shaped burrow in sand or mud at the bottom of the sea, often at considerable depths. Their tentacles spread out above the sediment to catch food particles.
