  2. 2. Meet the Arthropods<br />Insects, Spiders, and Their Relatives<br />
  3. 3. What’s an arthropod?<br />An arthropod is an animal that:<br />Is an invertebrate (has no backbone or spinal chord)<br />Has jointed limbs<br />Has a segmented body<br />Has an external skeleton (exoskeleton) made of a substance called “chitin”<br />
  4. 4. Arthropods Are Everywhere<br />You can find arthropods everywhere: in a yard, on a street, in a pond, in the sea.<br />So what are they?<br />This creature is an ant, which is an insect. Insects are a kindof arthropod that have three body divisions (head, thorax, and abdomen) and six legs.<br />The feelers on its head don’t count as legs.<br />
  5. 5. This beetle has a segmented body, an exoskeleton, and six jointed legs. Is it an insect?<br />
  6. 6. Where are the beetle’s legs?<br />Circle them.<br />
  7. 7. Most insects are larvae before they become full grown. <br />Larvae include the grubs and caterpillars that you may have seen in a garden. Later they mature into adult insects.<br />
  8. 8. Butterflies and moths are insects.<br />They have six legs.<br />When butterflies and moths first hatch from their eggs, they are caterpillars. But they are still insects.<br />
  9. 9. When the hornworm moth is a larva, it looks like the picture below. Is it still an insect?<br />
  10. 10. Arachnids are another kind of Arthropod.<br />This creature is a raft spider.<br />Spiders are arachnids. arachnids are a kind of arthropod that have two body sections (cephalothorax and abdomen) and eight legs.<br />
  11. 11. Scorpions are also a kind of arachnid.<br />Besides their legs, arachnids also have other appendages, which do different things, depending on the kind of arachnid.<br />The scorpion is an arachnid that has eight legs. <br />It also has a pair of claws.<br />
  12. 12. How many legs does a spider have?<br />6<br />8<br />12<br />
  13. 13. Circle the spider.<br />
  14. 14. Another common class of arthropods are crustaceans.<br />Crustaceans have several body segments that are grouped into a head, a thorax, and an abdomen. <br />The head and thorax may be fused into one piece, and the whole body may be covered by a carapace. Crustaceans have at least 10 legs.<br />The crab on this slide is a crustacean.<br />
  15. 15. You may have eaten a crustacean.<br />Most crustaceans live in water. Lobsters, crabs, shrimp, crayfish, and barnacles are crustaceans. A few live on land, like woodlice.<br />
  16. 16. Which animal is a crustacean?<br />Scorpion <br />Moth<br />Shrimp<br />
  17. 17. There are other kinds of arthropods.<br />For example, there are the myriapods, which include centipedes. Centipedes have a pair of legs for every segment of their bodies.<br />
  18. 18. Circle the insects.<br />
  19. 19. How many legs does a crustacean have?<br />6<br />At least 10<br />8<br />
  20. 20. Draw a circle around the arthropod that is not an insect, an arachnid, or a crustacean.<br />
