AbstractEchinoderms are exclusively marine deuterostomes with about 7000 described living and roughly 13,000 extinct species. They are extremely diverse, occurring from the intertidal to the abyssal zones. They are unique among Bilateria for the secondary pentaradial symmetry of their body.

Abstract Echinodermata is a bilaterian phylum with a body plan that has diverged significantly from the common bilaterian plan. Echinoderms are pentaradially symmetrical and have a unique type of mesodermal skeleton that lies just under the integument.

The Echinodermata are certainly one of the most unusual and interesting phyla from the biomineralization point of view. They all live in the marine environment. The five major taxonomic classes (Asteroidea or sea stars, Ophiuroidea or brittle stars, Echinoidea or sea urchins, Crinoidea or sea lilies, and Holothuroidea or sea cucumbers) have quite ...

This chapter describes the taxonomy of Echinodermata, a diverse group of organisms consisting systematically of five classes including sea stars (Asteroidea), brittle stars (Ophiuroidea), sea urchins (Echinoidea), sea cucumbers (Holothuroidea), and feather stars (Crinoidea). It covers their life cycle, ecology, and general morphology.

Abstract Most echinoderms have a distinctive radial pattern which may take the form of five arms radiating from a central disk (Fig. 15. I) or a more globular or cylindrical shape, again with structures arranged in five rows (or multiples of five) (Fig. 15.2).
