Fireworm

It's common name is the fireworm, but it is known in the scientific community as Eurythoe complanata. It has  white spines that break off into the skin which can cause horrible burning and itching. It's habitat is along the low-tide line up to 50 feet deep, coral reefs, and flat sea bottoms. It is currently not listed as endangered or threatened. The Fireworm has 4 eyes and 5 tentacles. It moves by contracting and elongating its body shape. I chose this animal because of its interesting look and its method of attack and self defense.
