Creature:Rock Snail

The Rock Snail is a unique species of nonsentient gastropods due to the fact that while its main body is carbon-based, its large shell is silicon-based. While scientists are still trying to figure out how this trait evolved in this and other species, the Rock Snails themselves are content to simply move about and devour carrion.
