What is the maximal age a Grévy’s zebra reaches?
An adult Grévy’s zebra (Equus grevyi) usually gets as old as 26 years.
Grévy’s zebras are around 406 days in the womb of their mother. When born, they weight 40 kg (88.18 lbs) and measure 8 cm (0′ 4″). As a member of the Equidae family (genus: Equus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 2.7 meter (8′ 11″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
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.
