I don't where I heard this, or if it is true, but it has been my favorite (maybe fake) animal fact:

There is a reason the stripes are BLACK and WHITE. One absorbs the light and the other reflects, which in turn makes a slight difference of air temperature right above the skin surface. The difference of temperatures in certain areas cause (slight) differences in air pressure. This can cause a shallow "wind coat" around the Zebra (and more pronounced when the animal is moving) because of the air pressure deltas all over its skin. This helps Zebra's regulate body temperatures in some very hot climates.
