The Przewalski (pronounced zeh-val-skee) or Mongolian wild horse is the sole surviving genuine wild horse in the world. Przewalski horses are among the most threatened wildlife species in the world. The entire world population consists of no more than 1,435 individual animals. It is also unique that after their extinction from the wild in the 1960s and after more than thirteen generations in captivity the Przewalski horses were reintroduced into their natural environment in Mongolia
