The stallion defends the herd against potential rivals and predators such as hyenas. A zebra can become up to 20 years old or in a zoo up to 28 years old. The zebras recognize each other by their stripe pattern and by their smell. Some species have narrow close set stripes, while others have smaller broadly set stripes. Zebras like to help groom each other.
Some zebras are now extinct.
