Water Bear

Water Bears are on 2 different episodes, and are #1 on Survivors, and #1 on Living Dead. They can survive anywhere on the planet, from on top of the Himalayas to the bottom of the ocean. Dry deserts, and freezing arctic waste lands. Hot springs and humid rain forests. They can even survive in your own back yard. Water bears are very small microscopic creatures. You can find them where ever there is moss or lichen. They can survive extreme conditions by retracting all their legs, and losing 99% of the water in their body. This is how they can survive temperatures as low as -200 degrees Celsius, as high as 150 degrees Celsius, 570,000 roentgens of radiation, over 1000 times the amount a human could withstand, and even 120 years in the desert with nothing to drink. A scientist dropped a water bear in the middle of the desert, and later scientists where surprise the water bear was still alive, when they added water to the moss 120 years later. They are so tough, they can even survive the vacuum of space.
