Interesting facts

I thought we could start a thread for sharing facts we love or find interesting/fun. Next time we're due to be in a social situation where it might be expected to share a fact as part of introducing ourselves, we can have this thread as a resource to look through so we have something ready. And at least as importantly I think, this can also be a space for info-dumping favourite facts about special interests. I'll start:

  • Chameleons change colour primarily for communication rather than camouflage. In males, brighter colours can be a mating display or sign of aggression. In females, they indicate a `No` to mating, while paler colours mean consent or surrender. Chameleons change colour by altering the distance between crystals in their skin, with brightness increasing the closer the crystals are packed together.
