Name two animals (other than polar bears and penguins) which live in the polar regions of the earth.

Answer

### Step-by-Step Solution

1. **Understanding the Polar Regions**: The polar regions are located at the North Pole and South Pole of the Earth. These areas experience extremely cold temperatures, especially during winter, and are covered in snow for a significant part of the year.

2. **Identifying Animals in Polar Regions**: While polar bears and penguins are well-known inhabitants of the polar regions, there are other animals that also thrive in these harsh conditions.

3. **Example 1 - Arctic Fox**: One such animal is the Arctic Fox. This fox is adapted to live in the Arctic environment. It has thick fur that provides insulation against the cold, and its white coat helps it blend into the snowy surroundings, providing camouflage from predators.

4. **Example 2 - Reindeer (Caribou)**: Another animal found in the polar regions is the Reindeer, also known as Caribou in North America. Reindeer are well adapted to cold climates with their thick fur and hooves that help them walk on snow. They are also known for their migratory behavior, moving to find food during the harsh winter months.

5. **Conclusion**: Therefore, two animals that live in the polar regions, other than polar bears and penguins, are the Arctic Fox and the Reindeer.
