Centipedes are arthropods belonging to the class Chilopoda of the subphylum Myriapoda. They are elongated metameric creatures with one pair of legs per body segment. Centipedes are known to be highly venomous, and often inject paralyzing venom.

Despite the name, centipedes can have a varying number of legs, ranging from 30 to 354. Centipedes always have an odd number of pairs of legs. Therefore, no centipede has exactly 100 legs. Centipedes are flexible, dorsoventrally flattened arthropods.

  • Millipedes belong to Class Diplopoda and are more rigid arthropods distinguishable by their subcylindrical shape. Centipedes have one pair of legs per body segment, while millipedes have two pairs.
  • Caterpillar is the common name for the larvae of members of the order Lepidoptera (the insect order comprising butterflies and moths).
  • Leeches are segmented worms that belong to the phylum Annelida and comprise the subclass Hirudinea. Like the oligochaetes, such as earthworms, leeches are hermaphrodites.
