See it on NASA's siteTardigrades are extremophiles, known for surviving conditions that would kill most other animals. They can go decades without food or water and endure extreme temperatures, pressures, and radiation. This image shows a tardigrade in moss, its natural habitat. Scientists have even tested their survivability in the vacuum of space.
