Spiny-skinned (Echinodermata)

Spiny-skinned (Echinodermata)



These animals are radially symmetrical -they have no distinct front and back, only a top and a bottom. The 6,000 species are usually found in tide pools along the seashore. The classes are: Asteroidea - starfish such as the Six-rayed Star above (Leptasterias hexactis); Ophiuroidea brittle stars; Echinoidea including sea urchins and sand dollars, Holothuroidea -sea cucumbers; and Crinoidea.
