The sea cucumber is an echinoderm of the class Holothuroidea, with an elongated body and leathery skin, which is found on the sea floor worldwide. It is so named because of its cucumber-like shape. Like all echinoderms, sea cucumbers have an
endoskeleton just below the skin.

Instead of a rigid skeleton, sea cucumbers have a muscular body well that contains only microscopic skeletal ossicles. The muscular body wall provides support, and so does the water inside the cucumber's large body cavity. This "water skeleton" also acts like a circulatory system.

The 'skeleton' of a sea cucumber is made up of microscopic overlapping plates, and these plates are referred to as ossicles.
