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.

  • Parthenogenesis (noun) : masturbation with consequences

  • Oh and heres a thought ive lived with for some time now, that you have just jogged. As you can see the mighty tardigrae poops galaxys. Imagine for a second our universe was just the atom of another larger being we could never comprehend. We are nothing but beings that live on a spec inside these poop galaxys that are based in this atom sized universe. All hail the might all knowing, universal tardigrae! Hail tards

  • MOARRRRR!!!!!!! The people demand MOARRRRRR!

  • this was awesome and hilarious 😂 glad I found your channel!

  • So every time we drink water, we accidentally drink them? I’ll never drink water again...

  • I really want to hear what you’d have to say about the bag worm moth caterpillars little stick cabins they glue to their backs

  • Narwhal???

  • Started watching this through my phone speakers and it freaked my bearded dragon out. She started waving to show submission and puffing out to make herself look bigger. She did not calm down until I turned the video off.

  • Christ Jerry get your act together (kidding of course)

  • How many complaints would I get if I sent this to all my Biology students? I may be about to find out. POV tardigrade porn is suitable for the over 12's, right internet?

  • Hello Frank, I hope you read this. I just learned about the existence of the (more or less spooky) "Potoo", or "common potoo" (Nyctibius), and I would love to learn about it. By you :)

  • that was a good one!

  • I have a hard time believing aliens don't exist after seeing this. I thought Jerry did a great job in those models! 👍

  • Please make a video about terrestrial isopods. They are gaining popularity in the pet community and I have them. Would love to see a video on them from you

  • (“

  • It isn't good for them to obtain or get close to Borealis,otherwise not to mention 7 hours but not even 7 minutes war...

  • 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.

  • Jerry is very good at making models, he probably has a curiosity shower every day before work

  • I love Tardigrades! I think they are so amazing. Thanks for teaching me more about them. I've loved and shared your videos since I first discovered your Sad Cat Diary. Your voice and manner of speaking are the best 😁

  • *Jerry is what you'd call "Passive-aggressive"*

  • Do a true facts about cockroaches

  • This is the first time frank made a video about an animal they did before

  • Our universe is made up of tardigrade $#!+

  • Great movie! I hope that someday in the future I will get an audience like yours. Please visit my channel, maybe you can advise me something :)

  • 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?

    • Plenty of creatures do eat them, which is one of the few ways to kill them.

  • “It looks like a galaxy.” Wait,,, Is our whole universe *a water bear’s poop???*

  • Whats the name of the song at the very end?

  • It’s official. I will never get enough of you and Jerry.
