Vibrations
Another fascinating thing about caves is its capability to survive extreme environments. For instance, bats and the Olms salamander use echolocation and electro-sensation to feel around their surroundings in finding their way around. These aren’t the only species who do this, but this also goes for rare fish species who no longer use their eyes anymore. These fish live in their cave pools and find it easier to move around using vibrations, otherwise known as a lateral line that hits the fish’s vertebrae.
