Echinoderms Research Paper
Echinoderms
Echinoderms are a major group of marine animals. Many echinoderms have radial symmetry meaning have 5 or a multiple of 5 arms. Echinoderms are animals without backbones and with spiny skin. Some echinoderms include starfish, sea urchins, sea urchins, brittle stars, sand dollars, and feather stars. Crabs, shark, eels, otters, sea birds, and octopi are some of the echinoderm’s predators. Echinoderms are scavengers of the ocean floor. They live off of microorganisms that are floating near the bottom of the ocean. Most echinoderms live in the ocean, from the intertidal to the abyssal zones. They are very important to the food chain (mostly underwater animals).
