= __**Sea Cucumber!**__ =
 * Sea cucumbers are echinoderms.
 * When threatened, cucumbers can contract their muscles and shoot out water from their body making them shorter, thicker, and harder.
 * Some can even shoot out their insides and then go and grow new insides.
 * their diet consist of dead and decaying organtic material, planktin and algy. They are echinoderms which means they are related to starfish.
 * The mouth and bottom are located at opposite ends of the body. The mouth is surrounded by tentacles
 * They start out as small larvae with no skeleton and it's ringed by tiny hairs called cilia. It uses the cilia to move through the water.
 * The sea cucumber then changes into the tube shape of an adult.




 * Sea cucumbers move at night to look for food. During the day, they lie still on rocks or bury themselves in sand or mud. They can be found in shallow tide pools to the deepest oceans. Sea cucumbers have been found at 33,500 feet deep in the ocean!
 * Sea cucumbers communicate with each other by sending hormone signals through the water.

Nervous system
 * Sea cucumbers have no true brain. A ring of neural tissue surrounds the oral cavity, and sends nerves to the tentacles and the pharynx. The animal is, however, quite capable of functioning and moving about if the nerve ring is surgically removed, demonstrating that it does not have a central role in nervous coordination. In addition, five major nerves run from the nerve ring down length of the body beneath each of the ambulacral areas.
