Holothuroideans are the sea cucumbers. They are sausage-shaped and have fleshy bodies with the skeleton reduced to a few ossicles in the body wall. Tentacles surround their mouths and help them to eat, pushing food towards their mouths. They crawl or burrow into soft sediments using muscular movements of the body wall.
