What is the maximal age a East African oryx reaches?
An adult East African oryx (Oryx beisa) usually gets as old as 20 years.
When born, they weight 3 grams (0.01 lbs) and measure 2.9 cm (0′ 2″). They are a member of the Bovidae family (genus: Oryx). Fully grown, they reach a bodylength of 54.5 cm (1′ 10″).
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 East African oryx (Oryx beisa), also known as the beisa is a species of antelope from East Africa. It has two subspecies: the common beisa oryx (Oryx beisa beisa) found in steppe and semidesert throughout the Horn of Africa and north of the Tana River, and the fringe-eared oryx (Oryx beisa callotis) south of the Tana River in southern Kenya and parts of Tanzania. In the past, some taxonomists considered it a subspecies of the gemsbok (Oryx gazella), but they are genetically distinct; the diploid chromosome count is 56 for the beisa and 58 for the gemsbok. The species is listed as Endangered by the IUCN.
