Invertebrates - What are Arthropods?




Arthropods are a group of animals that are invertebrates. There are more arthropods than any other kinds of animals on Earth. Arthropods have a type of skeleton outside their bodies called an exoskeleton. They also have segmented bodies and jointed attachments called appendages.
The exoskeleton is a waxy covering. It protects the animal and helps prevent evaporation of water.  The exoskeleton doesn't grow so the arthropod has to occasionally shed this covering and grow a new larger exoskeleton. This process is called molting. It takes awhile for the new exoskeleton to get hard and protect the animal.

Examples of arthropods are:
  • insects
  • arachnids
  • centipedes
  • millipedes
  • crustaceans


Listed below is a cool slide show link and books for the kids to learn more about arthropods.

  2. I love your site! The craft ideas are adorable but not too difficult at the same time. When I go back to work in January I definitely will be using some of the ideas (if that is alright!)
