A family of marmots prepares for their upcoming hibernation in a den 6 feet underground. As they prepare for their 6-month sleep, marmots dramatically lower their body temperature and survive on their body’s storage of fat and water. They only wake once every 2 weeks to rev up their heartbeat and visit a nearby tunnel used as a toilet.
