How many baby Grévy’s zebras are in a litter?
A Grévy’s zebra (Equus grevyi) usually gives birth to around 1 babies.
Each of those little ones spend around 406 days as a fetus before they are released into the wild. Upon birth, they weight 40 kg (88.18 lbs) and measure 3.1 cm (0′ 2″). They are a member of the Equidae family (genus: Equus). An adult Grévy’s zebra grows up to a size of 2.7 meter (8′ 11″).

The Grévy’s zebra (Equus grevyi), also known as the imperial zebra, is the largest living wild equid and the largest and most threatened of the three species of zebra, the other two being the plains zebra and the mountain zebra. Named after Jules Grévy, it is found in Kenya and Ethiopia. Compared with other zebras, it is tall, has large ears, and its stripes are narrower.The Grévy’s zebra lives in semi-arid grasslands where it feeds on grasses, legumes, and browse; it can survive up to five days without water. It differs from the other zebra species in that it does not live in harems and has few long-lasting social bonds. Stallion territoriality and mother–foal relationships form the basis of the social system of the Grévy’s zebra. This zebra is considered to be endangered. Its population has declined from 15,000 to 3,000 since the 1970s. However, as of 2008, the population is stable.
