As of 2023, how many living species of zebra are there in the world?

Zebra are African equines with distinctive black-and-white striped coats. There are three living species: the Grévy's zebra (Equus grevyi), plains zebra (E. quagga), and the mountain zebra (E. zebra). Zebras share the genus Equus with horses and asses, the three groups being the only living members of the family Equidae. Zebra stripes come in different patterns, unique to each individual. Several theories have been proposed for the function of these stripes, most evidence supports them as a deterrent for biting flies. Researchers still don't actually know why the stripes work. Most theories suggest some visual illusion. Perhaps, up close, the stripes affect how biting flies perceive a zebra's motion. Or from afar, stripes may scramble the outline of the animal's body. Zebras inhabit eastern and southern Africa and can be found in a variety of habitats.

Zebra species differ in social behavior, with plains and mountain zebra living in stable harems with an adult male or stallion, several adult females, and their young; adult females mate only with their harem stallion, while Grévy's zebra live alone or in loosely associated herds and establish territories which attract females and the species is promiscuous.

Zebra communicate with various vocalizations, body postures and facial expressions.

Historically they have been highly sought after by exotic animal collectors, but unlike horses and donkeys, zebras have never been truly domesticated.
