Tardigrades, tiny animals less than a millimeter long, can survive conditions that would kill most living things, including near-total drying out and extreme cold. When their environment dries up, many tardigrades curl into a shriveled form called a tun, in which their metabolism slows almost to a stop. When water returns, many of them uncurl and become active again.
