Oryx is a genus consisting of four large antelope species. They are adapted to live in hot and arid areas like Africa and Arabia. They are very striking in appearance and all have distinctive long horns (both male and female have horns).

On the other hand, Chiru, also known as the Tibetan antelope, is adapted to live in steppes and semi-desert areas of cold high mountains of the Tibetan Plateau. They are a small, unique species related to goats and sheep.

Therefore, the statement "Oryx is adapted to live in hot and arid areas whereas Chiru is adapted to live in steppes and semi-desert areas of cold high mountains" correctly describes the difference between the two species.
