Lots of great defecation physics here: “66 percent of animals take between 5 and 19 seconds to defecate. It’s a…small range, given that elephant feces have a volume of 20 liters, nearly a thousand times more than a dog’s, at 10 milliliters.”

Aaron, where do you even find this shit?

Sometimes it’s very obvious when it’s a non-Jason post, and other times I’m like, I guess Jason is feeling kind of irreverent today 🤷🏻‍♀️

Also, I feel like this research rhymes with one of my all-time favorite pages on the web: The Biology of B-Movie Monsters.

Maybe it's because I parent small children, but an article on poop science is an instant-read for me. Bonus: it lead me to this great NPR write-up of the winners of NASA's Space Poop Challenge (which I just learned was a real thing).

This flavor (sorry!) of research reminds me of the JBS Haldane essay “on being the right size” about the physics/geometry/biological implications of size. Worth a read and has some very memorable quotes.

As the owner of a dog in a city, poop is a very important part of daily life. Now when I’m trudging around on dirty streets, I’ll just imagine I’m on the savannah instead with the elephants. Everything is connected.
