One of Earth's slowest moving mammals just got a lot faster as Zookeepers in Jerusalem Biblical Zoo strapped wheels onto the bottom of a tortoise. The ten-year-old African Spurred Tortoise, named Arava, received her new set of wheels after suffering from a rare medical condition that paralyzed her two hind legs.
