#junkoff
And who could forget #JunkOff? Animal genitals are diverse as hell, and when carnivore researcher @annewhilborn.bsky.social launched the hashtag, biologists rose to the occasion. As reporter Stephanie Pappas put it: "If the eyes are the windows to the soul, the junk is the window to evolution" 🧪
#JunkOff: Why Animal Genitals Are Important to Science
A Twitter hashtag, #JunkOff, illustrates the steamier side of biology — and its importance to understanding evolution.

For those not familiar, #JunkOff was probably one of the most delightful things to happen in science communication. An essential part of science twitter lore.

Sooo. Now that we are all here,

#JunkOff reboot?

Or would this be a revival season like the X-Files

I'm tempted to return to that shithole country just so some asshole has to endure my #JunkOff tweets from the golden age of Science Twitter

ICYMI This is one of the more obvious ways to tell it is a male cheetah you are dealing with #junkoff. They use urine to mark territories.

Same same, the #BestCarcass thread on the birdsite was a magical time https://www.livescience.com/57470-best-carcass-photos-on-twitter.html 🧪
Exquisite Corpses: Biologists Share #BestCarcass Photos
If you thought that biologists on Twitter couldn't top the genitalia-celebrating hashtag #JunkOff, you'd be wrong. Dead wrong.

Anyway, hiiiii Bluesky!

Writing the above feels kinda like Twitter circa 2014-18, which was a pretty fun time to be “here”.

Now if I can just figure out this whole feed thing... Also when do we do #JunkOff?
October 24, 2024 at 3:40 AM
Ahhhh, #JunkOff. Those were the days.

“Like science Twitter was pre ~ 2018. Idk if it will work but I'd love it if you guys were up for the challenge.”

#JunkOff 2.0!

How could #JunkOff not have "Barnacles Tell No Lies" posted yet? It's a classic. https://www.youtube.com/watch?v=Nd7o6ytz_LM #sciencemusicvideos

Chose science as a feed to follow and wasn’t expecting #JunkOff TBH.
November 19, 2024 at 7:19 PM
Unfortunately I don’t think the days of #junkoff will ever return. It was fun while it lasted!
February 14, 2026 at 4:46 AM
Ooh, I hope #JunkOff is here…

So there's at least one serious scientist who I respect, who likes outreach, and who thinks #junkoff isn't a great idea. #scicomm

(None of this is meant as a criticism of scientists who participated in #JunkOff or of the originator @AnneWHilborn )
