This might be the dumbest question ever asked here, but here we go. Tonight I was at Disney’s Animal Kingdom and we saw their bat display. I was looking at this one bat (who looked suspiciously like my ex wife) handing upside down sleeping and I got to wondering. Does that bat have to think about holding onto the tree branch while it sleeps or does it have a “parking brake” type mechanism that locks itself to the branch? Meaning does the bat grip the tree branch and forget about it or does it have to be aware and hold it’s grip even while asleep?
