The only living truly wild horse, but a subspecies that is not believed to be a direct ancestor of the domesticated horse. A Przewalski’s horse stands about 1.4 m tall at the shoulder, has shorter legs than a domesticated horse, an erect mane, and a generally dun-coloured coat; it has 66 chromosomes, whereas all other equids have 64. Przewalski’s horses live in small family groups, feeding mainly on vegetation. They live on the Central Asian steppe grasslands and have been reintroduced to areas of its former range in Mongolia from where it had disappeared. All living Przewalski’s horses are descended from nine of 13 horses captured in 1945, which themselves were descended from about 15 captured in about 1900. At present there are more than 300 living wild.
