Yak
Brrr, it's cold! The temperature dips to 40 degrees below zero way up in the mountains of Tibet, but it's one of the only places in the wild to find yaks. Luckily, these majorly massive oxen are specially equipped to tackle the fiercest weather.
For starters, the yak's got some great foul weather gear: a thick, shaggy coat to trap body heat, and 40-inch curved horns that he uses to dig under the snow for grasses, leaves and twigs. He's also got large hooves that allow him to walk across icy mountain passes and wade through deep snow without slipping or falling. These super snowshoes spread out his weight and give him good grip. Considering he can get up to 2,000 pounds and 11 feet long, that's no small feat...or should we say "feet"?!
