Gazelle

Professional Pronker: Characterized by their long slender legs, gazelles are medium-sized antelope. They are swift runners and jumpers, and when nervous or excited, will exhibit a behavior called pronking, a method of locomotion where the animal jumps vertically into the air with an arched back and lands on all four rigidly straight legs. Why gazelles do this is not clear. Some theories suggest that by making themselves more noticeable, they are signaling to predators that they are aware of the danger, or they may be showing off their fitness and strength to intimidate animals on the prowl for a meal.

From Africa to Asia: There are 14 species

Looking Good: Long, ringed horns sit on top of the heads of both sexes in many species, but female horns tend to be shorter. Fur color is usually countershaded, meaning the top part of the body is light brown and the belly is white.
