 * ECHINODERMS**
 * __Digestive system-__** Echinoderms have stomach and mouth areas. A few could possibly have a mounth on the bottom while their anus is on their top. An example of an echinoderm that can turn their stomach inside out and insert it into their prey's is a starfish. This specific species has a relatively large gut.-- **Abby L.**
 * __Nervous system-__** Echinoderms have poor nervous systems although the system itself is very complex. Every thing is centered around the esophagus. A important part of the nervous system is the radial nerves. Radial nerves help coordinate any activity the echinoderms do. Overall, the nervous system is an important system in an echinoderm's body. **--Sarah K.**

 * __Positive impact on humans-__** One positive impact echinoderms have on humans actually comes from something negative. Because the species balance is so fragile, if tampered with, humans have learned (or are learning that) they need to respect wildlife. **--Sarah K.**
 * __Negative impact on humans- Tara__**
 * __1 interesting fact-__** In Greek, the word Echinoderm means "Spiny Skinned!"-- **Abby L.**
