The Celsius scale was originally the reverse of what it currently is, with 100° being at the bottom and 0° being at the top! Eventually, it was changed and it stuck!
The most preserved dinosaur fossil ever is of a Psittacosaurus. This fossil is so well preserved in fact, that scientists were able see what it’s cloaca looked like.
For decades, the kilogram all around the world was calibrated to the Prototype Kilogram, a 1 kg physical cylinder housed in France. Over time, despite being kept in a vacuum-sealed case in a climate-controlled secure vault, it was found to actually be steadily losing mass due to normal degradation just from existing.
Nowadays, it’s no longer as much a concern due to the kilogram being formally defined relative to universal physical constants.
Some species of flatworm practice what is known as “penis fencing” to reproduce. All of them are hermafrodite and in order to mate they must duel with their sharp penises and try to stab eachother to inject sperm inside, impregnating the loser, but often also killing it.

Well ain’t that just throwing the baby out with the bathwater!
Okay, you win! I’m out! xP
I just came back to this thread. What did I start?! :)
Aww, i was enjoying our fact exchanges.
Me too. But, even good things must end. :(
