Coolest Animal In The World

Coolest Animal In The World Detail
They’re small. (Adults are between 0.1 mm to 1.5 mm long). They’re everywhere. (From the Himalayas to more than two miles beneath the sea.) And they’re polyextremophiles. (They can survive temperatures from above 300 degrees Fahrenheit to near absolute zero.)
But perhaps coolest of all, they look like bears.Tardigrades are not truly extremophiles as they are not adapted to live in extreme conditions, but rather they can survive and endure such exposure, waiting for better conditions to come along.
Recently these “water bears” became tardi-nauts, flying aboard the European Space Agency’s FOTON-M3 spacecraft in September, 2007. As part of the flight the tardigrades were exposed the vacuum of space as well as unfiltered solar radiation 1,000 times greater than that at the Earth’s surface.
And wouldn’t you know it, the little buggers survived. In fact, according to scientists, they retained the ability to reproduce after the spaceflight. Perhaps, the scientists speculate, the tardigrades did this by somehow repairing their DNA.
The remarkable spaceflight survival of the tardigrades has lent some credence to the theory of panspermia, the notion that the seeds of life may have originated elsewhere and drifted to Earth through space.
Think you’ve got a cooler animal than the tardigrade? Bring it...
