Can some animals live in space?

Yes! In 2007, European researchers shot a species of tardigrade into low-earth-orbit for 10-days where they were exposed to the vacuum of space, as well as solar/galactic cosmic radiation. Upon returning to Earth, a handful of the individuals exposed to all radiation survived and were able to produce viable offspring.

Can any animal breathe in space?

Humans, chimpanzees and dogs can live in a space environment for but a few minutes before the air in their lungs expands, gas bubbles out of their blood and the saliva in their mouths begin to boil. But more fundamental organisms such as bacteria and lichen can tolerate the absence of pressure and searing cold.

Do tardigrades live forever?

There is also some confusion between the tardigrade's sheer hardiness and its ability to live forever. In reality, tardigrades only have a lifespan of a few months – in the active state. This can (and is) interrupted by long periods where they are (to all intents and purposes) “dead.” But more on that later.

Can life exist in a vacuum?

Microbiologists have discovered extremophiles – microbes that can survive in extreme conditions – such as Deinococcus radiodurans, which can survive high levels of radiation, as well as a vacuum, a lack of water and cold. Microbes have been known to survive journeys into space.
