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.
Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue.In some species these can sometimes be enlarged to flattened plates, forming an armour.he harvested product is variously referred to as trepang, beche-bÃªche-de mer or. Balate sea cucumbers serve a useful role in the marine ecosystem as they help recycle, nutrients breaking down detritus and other organic matter after which bacteria can continue the degradation. process
