characteristics and classification

although it as common characteristicit connects, is not the black-and-white or also brown-white strips among themselves not more near related than to the other kinds from the family of the horses. The common characteristic of the strips is related also by the fact that a subspecies of the Steppenzebras, the become extinct Quagga, only strip at the neckhad and some other Unpaarhufer also beginnings of touching at the legs to show.

The strips formed probably evolutiv for camouflage before Tsetsefliegen. Since place the frequency spectrum of the Zebras shifts to higher frequencies, it is not within the visible pass band of the compound eyes thatStechfliegen. Thus it is not this no more recognized by. Another hypothesis is that the typical Streifenmuster serves the camouflage. By the strips dissolves outlined its body optically, so that the Zebra of Raubtieren is to be recognized with difficulty.
