Video of a Tardigrade, also called a Water Bear or Moss Piglet. After several tries trying to find one in moss collected from my roof and my yard, I finally found one in some moss collected at a nearby wildlife park.

They are much larger than I thought they would be. This video was recorded using a Tucsen 10Mp USB video camera mounted on the Trinocular port of an Amscope T-490B microscope at 4x and 10x.

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, it was discovered that 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.
