What animals can survive extreme temperatures (like outer space)

The water bear (Tardigrade) can, was wondering if there was anything else.

Pretty much nothing can survive the vacuum of space, and it's only THEORIZED that water bears can, it hasn't been tested.
You should look up archaebacteria, they tend to be called extremeophiles in the biologists world.

I seriously doubt that anything much larger than the tiny (1mm) water bear could survive the cold and vacuum of space. Since they have such short lives, it is unlikely that they would be adversely affected by the radiation. The fact that they can survive no air and subzero temperatures for up to two weeks opens up avenues of research into cryonics though.

the artic notothenioids are fish that live in the worlds coldest waters of antartica.the artic cod is the most common notothenioid in the antarticas deadly freezing waters.the artic notothenioids have a special kind of antifreeze in their bodys to keep them from freezing in antarticas deadly waters.htere a type of bug that can slow down its heart rate to preserve energy and it can survive being frozen in a block of ice for more than 100 years
