Many, many days behind on looking at this thread!
Wonderful, inspiring, and beautiful photos all. Thank you! According to the 'not always correct' Wiki:
Zebras are black or dark animals with white stripes and their bellies have a large white blotch for camouflage purposes. Some zebras have brown "shadow stripes" in between the white and black coloring.
Zebras are described as black with white stripes rather than the reverse for the following three reasons:
1. White equids would not survive well in the African plains or forests.
2. The quagga, an extinct Plains zebra subspecies, had the zebra striping pattern in the front of the animal, but had a dark rump.
3. When the region between the pigmented bands becomes too wide, secondary stripes emerge, as if suppression was weakening.
The fact that some zebras have pure white bellies and legs is not very strong evidence for a white background, since many animals of different colors have white or light colored bellies and legs.
