One of this is because catch zebre has am unique pattern, and then it's different to the others; and the others animals can recognize it.
Another one reasons is that the zebres with their stripes are camuflage in a vast herd and the predators can not see them.

The researchers think that zebras had black-coated, and enolved its with stripes.
