Zebras are herbivores and eat mostly different types of grass, but they also eat bark, herbs and shrubs. Zebras prefer full green grass that is short and near the ground.
The difference between these three types of zebras is only about where do zebras live and the answer is that they live at different places. One type of zebra wants to live on mountains and is known as a mountain zebras. Second type lives on plain, grassy lands and is called as Burchell's zebras. Third type of these animals is better known as Grevy's zebras. These zebras are the largest of all three types of the species.
