Wildebeest and zebras can migrate in harmony as they both prefer different parts of the grass when grazing. Wildebeests are short grass grazers while zebras have long front teeth which facilitates them in feeding upon longer grass. So when the herd enters a new area, zebras basically mow the whole area which helps wildebeest to feed upon soft parts of the grass... Another reason is that zebras have better eyesight (and hearing) and the wildebeests can "smell" the water so it's mutually beneficial!
There are three species of zebras: the plains zebra, the mountain zebra and the Grévy's zebra. The latter resembles a mule, while the former two are more horse-like. The Grévy's zebra is the largest and also the most threatened of the three species.
How to recognize them? Just look at:
- Ears: Large and round
- Belly and the base of the tail: No black stripes
