Any of many elongated arthropods, of the class Diplopoda, with cylindrical bodies that have two pairs of legs for each one of their 20 to 100 or more body segments
A millipede is a small creature with a long narrow body and a lot of legs. Any of about 10,000 species of the arthropod class Diplopoda, found worldwide. Most species live in and eat decaying plant matter. Some injure living plants, and a few are predators and scavengers. Millipedes are 1-11 in. (2.5-28 cm) long and have from 11 to more than 100 diplosomites, double segments formed from the fusion of two segments. The head is legless; the next three segments have one pair of legs each; and the remaining segments have two pairs each. In defense, millipedes do not bite; most species tuck headfirst into a tight coil, and many secrete a pungent, toxic liquid or gas
