Pill woodlouse. Coloured scanning electron micrograph (SEM) of a pill woodlouse (Armadillid- ium sp.). This small terrestrial crustacean (order Isopoda) has changed little in millions of years, and is considered a living fossil. It has seven pairs of legs, and a compound eye (brown) can be seen above one of its antennae. It has a segmented body, which it can roll into a ball when threatened. Woodlice are found throughout the world in moist and dark environments, such as in leaf litter and beneath rocks and logs. They eat decaying plant and animal matter. Magnification: x20 at 6x7cm size.
