Tardigrades are the only animals known to survive in the extreme environment of space, but you'll never be able to see one with the naked eye.

This is a tardigrade, also called a "water bear." It's a microscopic creature that is about 1 millimeter in length.

Scientists aren't sure where they evolved from and even speculate that they may have come from space.

They look at bit like caterpillars and some compare them to small bears.Â

Water bears are interesting creatures because they can withstand very high and low temperatures and other environmental extremes.
