vredina [299]

Answer:

Polar bears are found in very cold parts of the world where temperatures can drop as low as -20° Fahrenheit (-29° Celsius). Without proper protection, this weather can be deadly, so polar bears stay warm by utilizing their thick fur and fat, or blubber. Polar bears have evolved along with other Arctic animals to take advantage of minimal warmth, and can sometimes actually become too warm because their bodies are so efficient at trapping heat.

As for walrus', they cannot put on a coat to stay warm, but they can use layers -- layers of blubber! A walrus's hide is about one inch thick. Tucked underneath this tough skin is a layer of blubber. This layer of fat is from three to six inches thick. Just like our layers of clothes, a walrus's layer of blubber helps it stay warm.
