Astronomy Picture Of The Day : March 6 , 2013 apod.nasa.gov/apod/ap130306.html Is this an alien? Probably not, but of all the animals on Earth, the tardigrade might be the best candidate. That's because tardigrades are known to be able to go for decades without food or water, to survive temperatures from near absolute zero to well above the boiling point of water, to survive pressures from near zero to well above that on ocean floors, and to survive direct exposure to dangerous radiations. The far-ranging survivability of these extremophiles was tested in 2011 outside an orbiting space shuttle. Tardigrades are so durable partly because they can repair their own DNA and reduce their body water content to a few percent. Some of these miniature water-bears almost became extraterrestrials recently when they were launched toward to the Martian moon Phobos on board the Russian mission Fobos-Grunt, but stayed terrestrial when a rocket failed and the capsule remained in Earth orbit. Tardigrades are more common than humans across most of the Earth. Pictured above in a color-enhanced electron micrograph, a millimeter-long tardigrade crawls on moss.

Fascinating! Think I'll take the picture and stump the science teachers at work! Thanks, Cliff!

Is that a real photo of a real critter? It looks like it was sewn together out of clothes and is crawling on a green towel.

I looked it up. Those really are real pictures of a real critter. A really weird looking critter but a real critter nonetheless.

A platypus mixed with Darth Vader. ;D ;D you guys got to be joking.. that is a rubber hose with a nozzle on the end of a trench coat. four metal prongs for feet.. ;D I thought it was fake too when I first saw the pictures. It looks like something that somebody made for a science fair project or something. The creature actually is real though. I've been looking all over the internet trying to verify it but as far as I can tell those really are real photos. The little animal's nickname is the water bear.
