Bats always turn left when exiting a cave.

(6) Comments
I live in Western Australia and I got hit in the face by a bat turning right out of his cave, well more like a small deep hole in a low rock bed. So it's either only true in the northern hemisphere or it's false.
Dave's probabl right. The Coriolis Effect is way too weak to effect things like draining water or, presumably, bats.
bat turns have as much to do with the Coriolis Effect as toilets do, which is to say, "none"
nananananananananananananananananananananananana Batman!
Does that include toilet flushing direction?
That is not always true. In the Northern Hemisphere, bats exit their caves to their left. In the Southern Hemisphere, they exit to the right. This is due to the Coriolis effect, the same force which causes hurricanes and tornadoes to rotate counter-clockwise north of the equator and clockwise south of the equator. This effect is an inertial force caused by the earth's rotation. The bat's sonar interacts with the Coriolis effect so that's why they turn certain directions when exiting a cave, depending in which hemisphere they are in.
