Sea cucumbers are typically 10 to 30 cm (3.9 to 11.8 in) in length, although the smallest known species are just 3 mm (0.12 in) long, and the largest can reach 3 meters (9.8 ft).The body ranges from almost spherical to worm-like, and lacks the arms found in many other echinoderms, such as starfish.

These echinoderms can grow to 6.5 feet (two meters) by feeding on tiny aquatic animals, algae, and even waste material. Sea cucumbers recycle food particles into fodder for bacteria much like worms do in soil.
