Also known as a "barnacle." This sea creature makes home to a sharp and hard surface, in which it hides in while not feeding. The reason it is called a "Volcanus" is because it resembles a Volcano and a Anus at the same time. They cling to rocks, whales, sharks, and other ocean dwellings. Known for a high bacterial content, most SCUBA divers and snorkelers wear gloves when traversing underwater reefs to protect their hands from being cut. If cut by a Volcanus, the injury will not heal completely for a few weeks, thanks to the high bacteria percentage in the creatures hard surface. (Volkilnos the Volcanus Voyeur invented the term.)
