Tardigrades can survive dry periods by curling up into a little ball called a tun. Tun formation requires metabolism and synthesis of a protective sugar known as trehalose, which moves into the cells and replaces lost water. ... Live tardigrades have been regenerated from dried moss kept in a museum for over 100 years!
