Habitat: From southeastern Sudan to South Africa and west to Angola, in Somali-Masai
Arid Zone, Southern Savanna, and South West Arid Zone. The zebra is one of the most
numerous and successful large herbivores, adapted to a broad range of grassland
habitats. Zebras often intermingle with other animals, most commonly the wilderbeest
but also with topi and hartebeest.
The zebra is active mostly in daylight, spending nights preferably on short pasture re
safe from ambush. Zebras graze individually an hour or so at a time at night but mov
very little. Resting zebras often steep soundly, but at least one herd member remains s
