Nested Animal Groups

Animals can be sorted into groups that fit inside other groups. Every mammal is also a tetrapod, and every tetrapod is also a vertebrate.

In the picture

  1. A cat: a mammal, so it is also a tetrapod and a vertebrate
  2. A frog: a tetrapod and a vertebrate, but not a mammal
  3. A fish: a vertebrate, but not a tetrapod or a mammal

Examples

  • A dog is a mammal, so it is also a tetrapod and a vertebrate.
  • A goldfish is a vertebrate, but it is not a tetrapod or a mammal.
