Thanks for your response. I want to continue the conversation on bats so I won't respond about the other stuff.

Take a look at this. The bats are walking on all fours: https://youtu.be/ewmydjekJnU?t=62 This is not a vulnerable position as they crawl on all fours on cave walls rather then the ground. On the ground they are vulnerable, on the wall or ceiling of some cavernous structure they are safe.
