ENCHINODERMS

WHAT IT TAKES TO BE A ECHINODERM

Echinoderms are invertebrates that live in the sea. They have bilateral symmetry which is parts of an organism around a single main axis. They have a exoskeleton and water channels or tubes that enable them to move and bring food into their mouth. Some echinoderms are poisonous, especially sea urchins. They can be carnivore or herbivore. Most echinoderms are cold blooded but starfish have no blood.
