1. Animals that live in colder areas have to protect their bodies against extremely cold environmental conditions.
2. Their bodies cannot withstand such cold climates.
3. So, they have thick white fur on their body.
4. This provides an additional layer over their skin.
5. Thick white fur acts as insulator of heat and stops the heat transfer from body to outside and vice versa.
6. Animals in colder regions have thick layers of fat, because fat acts as an insulator and doesn’t let their body heat escape, which helps them survive in such extreme temperatures.
