What is the difference between the antelopes Oryx and Chiru?

The correct answer is option 1.

Key Points

• Oryx:
  • Oryx living in herds on deserts and dry plains of Africa and the Arabian Peninsula.
  • Classified as coarse grazers, oryxes feed on grasses and energetically dig for water-storing roots and tubers. They can go without drinking except under the harshest conditions, but they drink regularly where water is available.
  • Oryxes have an unusual social organization that is adapted to a nomadic existence in desert conditions. Isolation and low population density select against the dispersal of adolescent males, as is usual in social antelopes.

• Chiru:
  • Chiru also called Tibetan antelope, a small, gregarious, graceful antelope-like mammal of the family Bovidae (order Artiodactyla) that lives on the high alpine steppes of the Tibetan Plateau.
  • The chiru is the only genus of large mammals endemic to the Tibetan Plateau.
  • Despite its antelope-like appearance, the chiru is not related to antelopes or to gazelles but represents the last remnant of a group of ruminants that split off from the sheep, goat, and goat antelope lineages during the Neogene Period.
  • It was extremely abundant on the Tibetan Plateau and surrounding high-elevation alpine steppes, but now it survives only in the extreme climate of the Tibetan Plateau.
