Imagine this: there's a library in Portugal where bats are the nightly guardians of ancient books! 🦇📚 At the Joanina Library in Coimbra, these little nocturnal creatures help protect priceless manuscripts by eating insects that could damage the pages. The library even accommodates their tiny protectors by keeping the lights off at night and providing small spaces for them to roost. So, while you're dreaming, these bats are hard at work, keeping history intact! Isn't that just batty? 😉✨
