All About Echinoderms

Echinoderms are sea animals with spiny skin. Animals in this group include sea cucumbers, feather stars, brittle stars, sea urchins, sand dollars, and sea stars (also known as starfish). All these spiny-skinned creatures have some things in common: no eyes, no brain, and tube feet. In addition, in their adult stage they are benthic animals, spending most of their time on the bottom of the ocean. Learn how echinoderms can clone themselves with just a foot of the original and how some have stomachs that come out their mouth to devour their prey.

All About Cnidarians

Have you ever brushed up on a plant with sticky spines on it? It is called a nettle plant. Some nettle like animals that live in the water are called cnidarian such as jellyfish, sea anemones, and corals. These animals can pack a powerful sting.

Cnidarians are boneless, brainless, eyeless, and footless; they mostly are made up of a mouth and tentacles. Some have tentacles that hang below them called medusae, while others wave above them called polyps.  Jellyfish, Portuguese man of war, sea anemone, and coral are all part of the phylum cnidarian.

Learn which aquatic animal is actually a colony of jelly like creatures that function as one, how coral can bud to form a larger colony, how the coral reef is formed & how to protect it, and the fascinating life of a jelly fish!
