Step 1 of 4
- Webbed feet push through water well.
- That fits a water habitat.
- A thick fur coat keeps the body warm.
- It fits cold mountains, not a hot desert.
The rule
A body part fits when it helps the animal in its habitat.
- Webbed feet help a duck move through water. Skin between the toes pushes more water with each paddle.
- A thick coat helps a yak, a mountain animal, stay warm.
