How do bats find their way into caves more than 100 meters down?

How do they get there? Why do they get there? Is there any advantage to being that deep into the cave? These are the burning questions I’m asking myself while not doing my schoolwork.

I believe it’s to do with echolocation and bouncing the sound off the cave walls, helps them find their way down

(This could be wrong)

When you walk somewhere it doesn’t matter if it’s 100 feet away or 10,000 feet away. You’re simply navigating whatever is right in front of you.

They get there using echolocation, essentially they have their own built in radar so the lack of light doesnt hinder them. Caves are great locations because they are sheltered, secured, and the deeper into a cave you go, the warmer it gets, and the less exposed it is to the elements by the entrance. No predators can get you unless they can see in the dark and also reach the ceiling of the roof.

Actually, contrary to popular belief bats are NOT blind. They’re basically color blind, but their eyes are INCREDIBLY well tuned to see in the dark. Echolocation on bats is mostly used for hunting, and literal pitch black environments.

Also there’s roughly 200 species of large bat that don’t even have the ability to use echolocation, due to lack of proper anatomy.

Actually can’t think of a species of bat that IS blind.
