As their name implies, Arctic foxes live in the cold northern latitudes. Their white winter coats are the most familiar, but their fur is actually brown in the summer, which blends in better with the bare, rocky tundra. Arctic foxes have a very low surface area to volume ratio (they are very round) to help them conserve heat. They eat almost anything they can find, including lemmings, voles, fish, eggs, carrion, and berries.
