This phylum consists of radially or radially symmetrical aquatic invertebrates having unique stinging structures in the tentacles surrounding the mouth. While all echinoderms are marine, the different classes of echinoderms vary considerably in the details of their body design. Echinoderms have pentaradial symmetry and a calcareous endoskeleton that may possess pigment cells that give them a wide range of colors, as well as cells that possess toxins.

Studies on echinoderms indicate a low level of cell turnover in the coelomocyte population (<1.5% BrdU incorporation in 3 hours or 16 hours in star fish) and low levels of apoptosis following acute exposures to UV-B , UV-C, hydrogen peroxide, methylmethane sulfonate and benzo [a]pyrene ; however, the DNA repair capacity of coelomocytes from different echinoderm species has not been investigated. The phylum Echinodermata consists of about 7000 living species and the phylum is divided into five smaller classes. data, and Echinodermata (Cameron et al., 2000), as well as the recently-defined phylum Xenoturbella (Bour-lat et al., 2006).
