Okay, you may have already heard about the tardigrade, because we write about this awesome microbe every chance we get. But for those who are new to MindHut: it is our pleasure to introduce you to this adorable little badass. Measuring only a half-millimeter, the tardigrade must have the highest ratio of moxie to body size of any animal alive. It has more super-powers than all the Avengers combined, and it's ridiculously adorable to boot. It even has two pet names, the "water bear" and the "moss piglet," which sum up its diminutive charm.
