Sometimes known as the Imperial zebra, is the largest species of zebra. The species is named after Jules Grévy, a president of France, who, in the 1880s, was given one by the government of Abyssinia. In certain regions of Kenya, the plains zebras and Grévy's zebras coexist. Grévy's zebra was the first zebra to be discovered by the Europeans and was used by the ancient Romans in circuses. Later, it was largely forgotten about in the Western world until the seventeenth century.
Grévy's zebra differs from the other two zebras in its primitive characteristics and different behaviour. It was the first zebra to emerge as a species. All members of the family are of the genus Equus, but the genus is commonly subdivided into four subgenera; Equus, Asinus, Hippotigris and Dolichohippus. The Plains zebra and Mountain zebra belong to Hippotigris, but Grévy's zebra is the sole species of Dolichohippus. In many respects, it is more akin to the asses. Nevertheless, DNA and molecular data show that zebras do indeed have monophyletic origins.
Grévy's zebra feed mostly on grasses but they will also eat fruit, shrubs, and bark. They may spend 60-80% of their days eating, depending on the availability of food. Their well adapted digestive system allows them to subsist on diets of lower nutritional quality than that necessary for herbivores. Also, Grévy's zebras require less water than other zebras.
is similar to the ass in many ways. Behaviourally, for example, it has a social system characterised by small groups of adults associated for short time periods of a few months. Adult males spend their time mostly alone in territories of 2-12 km², which is considerably smaller than the territories of the wild asses. The social structure of Grévy's zebra is well-adapted for the dry and arid scrubland and plains that it primarily inhabits, in contrast to the more lush habitats used by the other zebras.
Grévy's zebra is considered endangered, partly due to hunting for its skin, which fetches a high price on the world market. Its also suffers habitat destruction, human disturbances at water holes and competition with domestic grazing animals.
