ECHINODERMS

CUCUMBERS, SEA STARS, BRITTLE STARS, URCHINS, SAND DOLLARS

Echinoderms include literally thousands upon thousands of species. Most live on the ocean floor, in deep or shallow waters, and often bury their bodies beneath sand. Others hide in rock and rubble. There are an infinite variety of shapes, sizes and colors. Many species are as yet un-named, and often, microscopic examinations are required to correctly identify. Scientists believe Echinoderms have existed for about 540 million years.
