You might know these furry creatures as snow monkeys. Other than humans, they're the most northern-living primates in the world. They live in the coldest climate of any nonhuman primate. The red-faced monkeys inhabit four of Japan's five main islands, with the northernmost populations living in subarctic forests in the mountains of the Shimokita Peninsula.
Snow covers the ground for four months every year in Shimokita, and winter temperatures average around 14 degrees Farenheit. Even snow monkeys need respite from brutal winter days. Beginning in the 1960s, the monkeys took a cue from humans and started bathing in the area's volcanic hot springs. Now that's how you fight the cold.
