This video was made in collaboration with Benedikt Pleyer, who is a gifted microscopist and has a wonderful contagious passion for discovering the incredible worlds that exist all around us. He has introduced me to all sorts of new creatures and I am fortunate to have met him.
Kita Williams reached out to me almost a year ago with her amazing Tardigrade footage, and I am so happy that she did. She has a knack for capturing these animals in way that gives them so much personality!
Bob Goldstein runs a lab at UNC Chapel Hill and has done incredible work on the Tardigrade (and much more.) He was kind enough to review my work to make sure I didn't screw the science up too much! I wish I could have included more of his work on the evolution of Tardigrades - but I hope to do that in a future episode on arthropods.

These seem to act almost like Styrofoam packing noodles, holding organelles in place and making sure things don't stick together as the cell shrinks" --what a genius explanation

    In 1979 I was on a secret mission with a team of specialists. We traveled to an area which I can only identify as LV-426. One of our operatives came in contact with one of these things and it attached to his face by wrapping around his head. Needless to say our mission did not go well and I'm convinced the "Company" is researching this thing for our weapons program.

    Because humans have the stupid bias that assumes advanced forms of life must be large, they've failed to realize that Tardigrades are the alien rulers of the universe who came here from a galaxy a trillion light years away to add earth to their empire.

    So what you’re saying is that a bag of tardigrades is essentially a bag of rice with protein that makes them come back to life after you poop them into the water in your toilet. Do we get nutritional value from them?
