Number 6903. This is a sowbug, a terrestrial crustacean in the order Isopoda; the vast majority of these are harmless scavengers on decomposing organic matter. They breathe through gills that must be kept moist, so keeping your environs as dry as possible will discourage them from staying. Click here for more information.
