I know from reading that a human in vacuum needs a space-suit to survive.

Is the body of any organism on Earth capable of living equally in vacuum, and on/below Earth's surface within the atmosphere?

    $\begingroup$ Any body? As in you're looking for an organism that is capable of surviving in a vacuum and with an atmosphere or you're looking for Chuck Norris? Assuming not the latter , google suggests this but it's an unreferenced Wiki point :/ $\endgroup$

Remarkably, Tardigrades are multi-cellular animals which can survive the vacuum of space.

  • $\begingroup$ I even think NASA sent a few of them up to space, brought them back to earth and awakened them... $\endgroup$

    $\begingroup$ "Tardigrades" are basically the answer to every biology question which begins with "can any animal...", aren't they? $\endgroup$ Commented Jul 18, 2013 at 6:59

Adding to Noah's answer, some lichens can survive the vacuum of space too. In an experiment led by Leopoldo Sancho from the Complutense University of Madrid, two species of lichen - Rhizocarpon geographicum and Xanthoria elegans - were sealed in a capsule and launched on a Russian Soyuz rocket on 31 May 2005. The lichens were in perfect condition when observed after the return to earth.
