Tardigrades (commonly known as water bears) have eight legs and are their own phylum on the tree of life. Some can survive temperatures close to absolute zero, temperatures as high as 151 °C (303 °F), 1,000 times more radiation than any other animal, nearly a decade without water, and even the vacuum of space.

    This is interesting and I also learned something new today. They definitely look like bears, hehe.

    A decade without water? Are any other animals close to this?

    So these Water Bears can basically live anywhere in the universe?
    Do they have an environment where they thrive?
    I did not know of such a creature.
    I live it.
