  • 1. Millipede/ Diplopoda Centipede/ Chilopoda Quade Walker & Sam Andrews 5/19/09 Period 2 Arthropoda Myriapoda
  • 2. Classification Of Animals
    • Kingdom – Animialia
    • Phylum – Anthropoda Jointed legs and an exoskeleton
    • Subphylum - Myriapoda “Many-footed” with a two segmented body
    • Class Chilopoda (centipedes “100 feet”) It has a flat, segmented body with a pair of legs on each segment.
    • Class Diplopoda (millipedes “1000 feet”) It has two pairs of legs on each body segment. The Greek translation is “ double footed ”.
    • Class Pauropoda (pauropods, pauropodans, and progoneates) Pauropods are a small (less than 5 mm), eyeless, pale terrestrial invertebrate with eleven segments and nine pairs of legs. Latin and Greek translate into “small-footed.”
    • Class Symphyla (pseudocentipedes and symphylans) small, blind, fast-running centipede like animals.
  • 3. Basic Body Form
    • Bilateral symmetry
    • exoskeleton
    • Head and segmented trunk
    • The trunk has many legs (Centipede has one pair for each segment, millipede has two pair for each segment.)
    • Centipedes body is flat, while the millipede is more of a cylinder shape.
    • Head has antenna, eyes and mouth
  • 4. Millipede Shedding Exoskeleton Shedding Exoskeleton
  • 5. Reproduction Method
    • Both the centipede and millipede have separate sexes.
    • The female lays eggs which are fertilized sexually by the male.
    • Some species lay the eggs in a "nest" where they are guarded by the female.
    • Others lay one egg at a time and then leave it .
  • 6. Feeding and Digestive system
    • Millipedes are herbivores mainly eating dead vegetation.
    • Centipedes are carnivores. Their first pair of legs inject venom to kill prey. They feed on insects, earthworms, and slugs. They also eat dead vegetation.
    • The digestive system is a gut that runs from the mouth to the anus.
    • The gut is lined with a protective outer covering called a chitin, that is shed every so often.
  • 7.  
  • 8. Circulatory system
    • It is an open system.
    • It has a hemocoele (blood cavity.)
    • They heart is located dorsally, or near the back.
  • 9. The Respiratory System
    • The centipede and millipede get oxygen delivered straight to the cells through tunnels that branch from spirals or holes in the body wall.
  • 10. Living Environment
    • Most Arthropoda Myriapoda live under rocks, wood bark, caves and in damp leaves.
    • They prefer dark warm places.
    • Centipedes and Millipedes are found world wide, except in polar climates
    • They are mostly nocturnal creatures
  • 11. Human Interaction
    • They avoid humans.
    • Some people eat centipedes
    • Some people keep them as pets (usually the bigger ones)
    • In some cultures millipedes are used medically. They treat everything from toothaches, earaches, joint illness, asthma, zits and more.
    • Millipedes are used in the study of robotics.
    • Their likeness are used in advertising (shoe commercials, air fresheners, etc.)
  • 12. Unique and interesting features
    • Milli means 1000 and centi means 100. Pede means foot. They don’t really have that many though.
    • Fossils prove they have been around for a very long time.
    • Millipedes protect themselves by curling into a ball and spraying hydrocyanic acid.
    • Some centipedes glow in the dark.
