Detailed explanation-1: -Antelope horns serve two main functions; intraspecific male combat (all species), and interspecific self-defence (or defence of young) against predators (both sexes).

Detailed explanation-2: -The horns of nountian gazelles are the most utilized form of defense against predation. They are used for butting small predators. The gazelle also has keen vision and can run at high speeds.

Detailed explanation-3: -Most deer species limit antlers to males, but both sexes of gazelles can grow horns, although males’ may be longer. A gazelle horn is a bony core encased in an outer layer featuring keratin and is often curved and ringed. While deer shed their antlers every year, gazelle horns are permanently attached.

Detailed explanation-4: -Their major predators are cheetahs, which are able to attain higher speeds, but gazelles can outlast them in long chases and are able to make turns more quickly. This small antelope can run extremely fast, up to 80 km/h (50 mph), and zigzag, an adaptation which often saves it from predators.
