I will always be fascinated by slime molds because they're big, visible, mobile organisms that are also unicellular.
-
you can't just make that many jokes about wombat poop and NOT link to an answer xD
-
To be fair I think I am indeed still a bunch of organs flopping around 😂😭
-
This host has been fantastic in this series. Get this man in showbusiness YESTERDAY!
-
This educator's vibe is exceptional!
-
Wombat poop is cube to help stack and mark territory.
-
I mean, there’s this other cool educational channel called Bizarre Beasts that goes over the koalas’ cube poop in one of its videos so I’m just saying. :3
-
About the wombat's square poop, apparently it's because "the grooved (intestinal) tissue and the irregular contractions over many cycles shape firm, flat-sided cube". In mammals, usually "the wavelike peristalsis of the intestinal muscles are consistent in all directions", but in wombats there are intestinal regions of varied thickness and stiffness (the softer regions squeeze slowly, and the stiff regions squeeze faster), which creates the difference in wombat feces (reference: Intestines of non-uniform stiffness mold the corners of wombat feces, by Patricia J. Yang et al.).

You are a genius I love the way you humorously educate and entertain us, keep up the great work.
-
Just discovered this host. He’s great. Very funny and dynamic
-
Same reason we have cities: it’s just more efficient for multiple, independent bodies to work together to get things done to ensure basic survival.
-
You're such a great presenter, doctor :) thanks for helping me learn this weird stuff
-
I kinda want to see Doctor Sammy's bumblebee mugs now
-
Sounds fun!
-
Looking the journey to the microcosmos microoscope at his side makes me so jelly, i couldn't buy one when they were available
-
I demand an episode about wombat poop!
-
Modern toilets no longer use those float balls. You can’t even buy replacements for them at the big box stores any more.
-
I noticed the Ghibli background in the intro! 😸

Kachoo! 11:28

Isn't Physarum polycephalum a macroscopic organism that isn't a multicellular organism?
