The Touch-Me-Not Sponge is found in shallow waters in the Western Atlantic Ocean and the Caribbean Sea. It is a massive sponge that grows to about 30 centimeters wide and 30 centimeters tall but can reach up to a meter in width. It has a main central cavity with thick walls. They have several openings called osculi that propel water out of the sponge. The consistency of the sponge is compressible, fragile, and crumbly. Handling it causes a painful sensation and numbness of the skin.
Sponges do not have a real circulatory system. They have flagellated cells on the surface of their bodies. These cells create a water current through the many pores in their bodies. They rely on keeping up this current in order to keep the water flowing through their bodies so that they can obtain food and oxygen and to remove waste.
