Zebra



Zebra



 Zebra Types:
There are three zebra species: the mountain zebra, the plains (or common) zebra, and the Grevy's zebra. The plains zebra includes six subspecies, and each differs in the pattern of their black and white stripes.


Huge Herds:
They all graze in large herds on tall grasses. Some zebra herds number in the tens of thousands, but within these larger herds are distinct family groups composed of a male, several females and their young.


Mysterious Stripes:
 It has often been suggested that the stripes of zebras serve as camouflage in tall grasses. But the fact that they make no attempt to hide and freeze when a predator is seen — indeed, they become noisy and active — seems to contradict this theory.
