Since most echinoderms have some type of calcareous support exoskeleton (actually often interlocking plates of calcium carbonate), there exists an extensive fossil record tracing echinoderm evolution. Yet, many aspects of their early evolutionary origins are confounded, such that the classification table below is but one of many interpretations ...

Using multiple phylogenetic methods at a variety of sampling depths we have constructed a well-supported phylogenetic tree of Echinodermata, including support for the sister groups of Asterozoa (sea stars and brittle stars) and Echinozoa (sea urchins and sea cucumbers).Cited by: 42

They have a shell, made mainly of calcium carbonate, which is covered by skin. The skin conatins cells to help support and maintenance the skeleton, pigment cells, cells to detect motion on the animal's surface, and sometimes gland cells which secrete sticky fluids or even toxins. The different groups of echinoderms

Echinoderm, any of a variety of invertebrate marine animals belonging to the phylum Echinodermata, characterized by a hard, spiny covering or skin. Beginning with the dawn of the Cambrian Period (542 million to 488 million years ago), echinoderms have a rich fossil history and are well represented

Diversity. Echinodermata has approximately 7000 described living species and about 13,000 extinct species known from the fossil record. This phylum is the largest without any freshwater or terrestrial forms. (Brusca and Brusca, 2003; Waggoner, 1999)Geographic Range. Mainly a marine group, echinoderms are found in all the oceans.

The epidermis consists of cells responsible for the support and maintenance of the skeleton, as well as pigment cells, mechanoreceptor cells (which detect motion on the animal's surface), and sometimes gland cells which secrete sticky fluids or even toxins. The varied and often vivid colours of echinoderms are produced by the action of skin pigment cells.Clade: Bilateria

Echinoderms can regenerate missing limbs, arms, spines - even intestines (for example sea cucumbers). Some brittle stars and sea stars can reproduce asexually by breaking a ray or arm or by deliberately splitting the body in half. Each half then becomes a whole new animal.
