Doubtless the lions fall about with laughter when they have difficulty picking out a particular zebra in the herd for the kill. (Lions have poor vision, in B&W only)>>>

Actually, Lions have excellent binocular vision which is PARTICULARLY adept at locating and distinguishing moving objects. They are also able to see very well in low light. I do not know about color, vs b/w, but this is not really a hindrance in hunting.

Not that it "proves" anything one way or the other, but it just happens to be a piece of extranneous data that somehow lodged between my ears...., one of those damn things that gets in the way when I am trying to remember where I left my keys.

You lose your keys too? Drives my wife nuts when I do it, "If you always left in them in the right place....". "SILENCE WOMAN!"

Anyway, the lions finding it difficult to pick out the one they are hunting in the herd because of the mess of stripes interfering with their perception is only a just-so story, but it sounds plausible to me. Zebras are social and there is also a hypothesis that they identify individuals using the stripes, a form of sexual selection.
