The young of which of these animals is not called a calf?

Zebras are African equines with distinctive black-and-white striped coats. There are three living species: Grévy's zebra ("Equus grevyi"), the 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.

The Gestation period for a Zebra is typically around a year. Usually, a single foal is born, which is capable of running within an hour of birth. A newborn zebra will follow anything that moves, so new mothers prevent other mares from approaching their foals as they become more familiar with the mother's striping pattern, smell and voice.

In English, the term "calf" is used for the young of various other large species of mammal. In addition to other bovid species (such as bison, yak and water buffalo), these include the young of camels, dolphins, elephants, giraffes, hippopotamuses, deer (such as moose, elk (wapiti) and red deer), rhinoceroses, porpoises, whales, walruses and larger seals.
