Wombats have fused bone like cartilage in their butts used to block their burrows from predators and apparently will twerk to defend and crush the skulls of the attackers against the burrow walls. https://www.australiangeographic.com.au/topics/wildlife/2020/11/wombat-bums-theres-more-than-meets-the-eye/
the endless inventions of nature. totally amazing 🤣
i mean, when did the idea of using its butt as a blunt object occur to this species? one individual did it in desperation, then taught others?
it's fascinating.
@holon42 but now we can say “killer wombat butt” with scientific accuracy.
