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.

    Well considering these things are microscopic I would definitely believe that they would "resist" radiation that can kill a human considering radiation goes through things at super speed to the point of knocking out atoms within your DNA thus fucking up your DNA and best case scenario killing your cells, the worst case is the cells go insane and turn into cancer, or possibly even severing some DNA strands that end up getting bunched into other pieces and becoming viruses! So yes i would say the fact that humans are quite a lot more vulnerable to radiation than an animal that is trillions of times smaller than us....

      @Un Pingouin de Sophistiqué I was curious, so I looked up how closely related tardigrades and arthropods(phylum that includes insects, crustaceans, spiders, scorpions, etc). It turns out that it’s most likely that tardigrades are an ancient form related to the ancestor to arthropods! (Info from Wikipedia)
