Millipedes do not have a poisonous bite, but many protect themselves by offensive odors produced by stink glands; some produce highly irritating compounds that can injure the skin or eyes of attackers; and some can roll up into a ball or spiral for protection. They are widely distributed in temperate and warmer regions, living in surface litter, under stones or logs, and in relatively humid surroundings. They feed mostly on decaying vegetation, although some will consume decaying animal food. Some species attack plant roots and cause crop damage.
Centipedes, with which millipedes are often confused, are carnivorous, have a single pair of legs on each segment, and a body that is flat in cross section. Millipedes belong to the phylum Arthropoda, class Diplopoda.
