Zebras can fall prey to lions, hyenas, and other African predators. Some Zebra species are endangered and protected, however, so humans aren't as much of a threat to them.
Zebra foals are born after a gestation period of a little more than a year. Usually, only one baby is born, but sometimes twins are, too. Foals can stand about 10 minutes after being born. They are weaned at 11 months
Every zebra has a unique stripe pattern. Just like fingerprints or snowflakes, no two zebras have the same stripes.
