This often saves individuals stray from the herd, who walk alone and unarmed. But more often zebras are surrounded by their own kind. It is highly unlikely that the lion (even an idiot and colorblind) will not notice the herd. However, zebra stripes are saving here.

As a result, a plan to attack the lion flies to hell. Himself zebras strips (each individual they are located in their own way) to help identify each other in the herd. Mankind also uses this kind of camouflage vests. They help to seafarers or not is hard to say, but judging by the fact that lions rarely attack them, rather than not.
