Water bear, SEM
Videonummer 12456443
| Water bear, animated scanning electron micrograph (SEM). Tardigrades (Macrobiotus sp.) are polyextremophiles and are able to survive in extreme environments that would kill almost any other animal. Some can survive temperatures of as low as 273 degrees Celsius (close to absolute zero), or as high as 151 degrees Celsius, 1, 000 times more radiation than other animals, and almost a decade without water. In September 2007, tardigrades were taken into low Earth orbit on the FOTON-M3 mission and for 10 days were exposed to the vacuum of space. After they were returned to Earth, many of them survived and laid eggs that hatched normally, making these the only animals known to be able to survive the vacuum of space. | |
