Millipede, New River Gorge National Park and Preserve, 2014.
Millipedes differ from centipedes in that their legs are paired on each body segment (after the third segment) while centipedes have one pair of legs per segment. Mostly, these animals coil up when threatened to protect their legs and hide out of sight most of the time. Interestingly, they have tiny holes (spiracles) on the sides of their body to allow them to breathe moist air. They are important in the food web because they eat everything from dead plant matter, fungi to other insects. Newly-hatched millipedes look similar to adults but have fewer segments. They'll add more segments after each molt.
