Nanorchestes antarcticus

Macromite is one of my absolute favorite blogs. The colored SEMs, very labor intensive pieces of art, are beyond belief. And it turns out that mites are equally as diverse as insects (if not more so), with all kinds of crazy evolutionary stories. From Macromite-

"Herds of hundreds of thousands of these mites roam parts of the Antarctic continent, presumably grazing on algae"

If you ever make it to Antarctica, make sure to keep an eye out for a herd of these .1mm marvels.
