Zebras are African equines famous for their distinctive black and white striped coats. Three species exist: plains zebras, mountain zebras, and Grevy's zebras.
Every zebra has a completely unique stripe pattern. No two zebras share identical stripes. Foals recognize their mothers by memorizing stripe patterns, scent, and voice. Scientists use stripe patterns to identify individual zebras in field studies.
Zebras have stocky bodies with relatively short legs compared to horses. Their powerful neck muscles support large heads. Zebras have excellent senses. They can run up to 40 mph and maintain steady speeds for long distances when escaping predators.
Zebra social structures vary by species. Plains zebras form stable family groups led by a dominant stallion with several mares and their offspring. These harems contain 5 to 20 individuals. Family groups remain together for years.
Zebras are herbivores that primarily eat grasses. They are less selective grazers than other herbivores and consume coarser, tougher grasses that many animals avoid. They may travel over 10 miles to water sources during dry seasons. They spend 60 to 80 percent of their time feeding, especially during dry seasons when grass quality decreases.
Zebras breed year round, though most births occur during rainy seasons when grass is abundant. After a gestation period of 12 to 13 months, mares give birth to single foals. Newborns weigh 55 to 88 pounds and can stand within minutes of birth. Young zebras reach independence at 1 to 2 years but females often remain with their birth herd.
No two zebras have exactly the same stripe pattern, like human fingerprints
Zebra foals can recognize their mothers by unique stripe patterns, scent, and voice
A group of zebras is called a dazzle or a zeal
Zebras can sleep standing up but only enter deep sleep when lying down near family
Grevy's zebras have the narrowest stripes and largest ears of all zebra species
Zebras have never been successfully domesticated unlike horses and donkeys
Scientists believe zebra stripes serve multiple purposes. Stripes may confuse predators when zebras flee in groups, creating a motion dazzle effect. Research shows stripes deter biting flies, which avoid landing on striped patterns. Stripes might also help regulate temperature by creating cooling air currents. Each zebra's unique stripe pattern helps foals recognize their mothers.
