The gregarious Oryx are desert-roaming antelope and can go three months without drinking water. They are capable of extracting moisture from succulent plants, which makes the Karoo a perfect haven for them. Both the males and the females have horns, which they use to protect themselves from predators – this chiefly being lions. They have a very clever technique to protect themselves, in which they will employ the trick of "playing dead". Through this ruse the predator will approach, whereupon the Oryx will jump up and kill it with its horns.
