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.

    When I die, I'm going to ask God two things:

    (1): What inspired Him to create Tardigrade, which may or may not have inspired us to make gummi bears and Pokemon?
    (2): Who the Hell would want a kale-flavored Caprisun?!

  11. Totally unrelated but…
    See the green thing that the tardigrade pushes? I can see something similar floating over my vision when looking at something bright. I swear I've first noticed it when I was a child and now in my teens that single "cell" has "grown" longer over the years. WTF is this.

  12. Jackulation says:

    “Some can survive temperatures lower than -270 degrees Celsius.”

    That’s incredible! That’s 3 kelvin away from absolute zero (all atomic movement stops)

  18. MB with consequences… that's the moment you got me. Nicely done

  19. Ruby Johnson says:

    Someone tell me why I was literally listening to the adventure zone Podcast episode where they fight these and this came up on my notifications… I was really spooked😂😳

  20. Suzanne Winz says:

    Don't mess with the Moss Piglet. Put that on a T-shirt! 😀

  21. Frozen June says:

    WOW! I actually learned way more than I thought I would.

  22. commatoes says:

    Tardigrade sex -> The PornHub search where you zero results and a WTF?

  23. Aber Aber says:

    Weirdly, this made me very very happy.

  24. Imagine if that's how the world was created, a bunch of water bears pooped

  25. There are also 35 collections of—
    Oh, there’s David Attenborough. Show-off.

  26. i want evolution to make it bigger so i can pet it

  27. Butters says:

    It's ok zefrank1, you're our David Attenborough.

  28. Nathan Chase says:

    Those little legs are amazing

  29. If I were a tardigrade I'd move out from home.
    Why live in the shrubbery when you could have a throne?
    Pressure wouldn't squash me and fire couldn't burn.
    These are the things that I never will learn.

  30. @zefrank1 Love your stuff so much! It's good to hear you laugh too hehe

  31. LongGoose says:

  33. nightsky j says:

  34. "It is how a tardigrade do"

  35. Jackulation says:

    The radioactive resistance is also present in the parasitic wasp species Habrobracon hebetor, if you're looking for another video idea 😉

  36. I swear to God, you and your channel need to get its own tv show on Netflix or Hulu or something. I wish I watch new episodes every day lol

  37. Mr. Miyabi says:

    Imagine being an animal that shits space

  38. kelammo says:

    Think master nation with consequences! I’m dead! 😂

  39. adam mac says:

    Imagine if the Milky Way is just one Tardigrade's poop crystal.. as if we're all just microscopic organisms to some much, MUCH larger beings.

  40. Damn it jerry i told you i wanted photos of spider man not photos of a spider in a mat.

  41. Td l48 says:
