FUN FACTS

1. Grevy's zebras are unusual because they do not form long lasting bonds like the plains zebras and horses. Their group composition may change on an hourly basis.
2. Within an hour after it is born, a foal can run with the rest of the herd and can recognize its mother with smell and sight.
3. Stripes may cause confusion by making it hard for a predator to single out an individual.
4. Each zebra has a unique stripe pattern, like a person's fingerprint.

ECOLOGY AND CONSERVATION

The major threats to the Grevy's zebra are introduced livestock that compete for grazing land and hunting for zebra skins. Zebras are beneficial to other wild grazers because they clear off the tops of coarse grasses that are difficult for other herbivores to digest. Also, zebras eat course grasses that grow on marginal lands where cattle do not do well.
