Class is one level of classification. You can really see the differences between animals when you look at class. Animals in the same class have at least one thing in common with each other. There are five classes of animals in Simon's phylum (chordata, animals with a backbone)
  1. mammals
  2. reptiles
  3. amphibians
  4. birds
  5. fish
You are a mammal. Would you think that you and Simon are in the class?

Think about Simon. Describe him. Write down everything you can see about him. Some things to think about:

  • What does he look like?
  • What do you think he eats?
  • How do you think he moves?

Now think about yourself. Ask yourself the same questions. How are you and Simon similar? These similarities are what put you and Simon in the same class - Mammalia.

How are you and Simon different? Write down the differences you find. Because of those differences, you and Simon are in different orders, families, genera, and species (all the smaller levels after class).
