Sea Cucumber

The sea cucumber group is related to the sea stars, and other echinoderms. Its outside is covered with hundreds of tiny feet which have suction cups at their ends known as tube feet. It feeds with feathery tentacles, sifting the water to trap a food item. They have a water vascular system to allow movement. Cucumbers have the distasteful habit of extruding their intestines and its contents when they perceive a threat.
