Echinoderms can only be found in water, as they are aquatic. Some characteristics of Echinoderms are: Hard Skin, have arms or spines, have 5 body parts, organs found towards centre of body. Examples: Star Fish, Sea Cucumber, Sea Urchin
Echinoderms are not like any one animal. Echinoderms are invertebrates (no backbone), and are all animals with spiny skin (echin-spine, derm-skin). Some examples are starfish, sea urchins, and sea cucumbers.
Echinoderms are in the Animalia kingdom.
echinoderms
The major difference between echinoderms and other invertebrates is that there are few examples echinoderms that do not live in ocean water and none live on land. There are examples of other invertebrates that live in both fresh and salt water and on land. Echinoderms also display radial symmetry as do the jellyfish and sea anemones. If you want to tag the one thing that echinoderms have that no other living invertebrate has, you would probably have to point to their water vascular system (see link). If you have the McGraw Hill science textbook for 6th grade then you are all set. Look on pages A40-A48.

yes crabs are echinoderms because they have spiny skin
