Zebra

You can't really miss a zebra when you see one in the open grassland. It's not at all clear why they have this black-and-white pattern; it doesn't seem much good as camouflage and neither does it appear to be anything to do with sexual selection.

This piece in the Guardian suggests that it may offer some protection from parasitic flies.

Whatever the explanation, they are stunning animals to see. This was in Kruger National Park - a of collection photos from our day there is here.
