Tardigrades are within the Superphylum Ecdysozoa and about 400 species make up the Tardigrada phylum. These 8-legged segmented bits of awesomeness live in water and are the some of the most extreme of all the extremophiles.  Tardigrades are able to survive near absolute zero (-459 degrees F) all the way up to 304 degrees F.

Here is a short video from National Geographic:

Tardigrades are being utilized in research as a model system to examine development driving the evolution of morphology. Follow this link to the Goldstein lab at UNC-Chapel Hill.
