> [Gaselles] repeatedly jump as high as they can, springing vertically into the air with all four feet raised. > The signal this sends to predators is essentially: “I’m so fit that I can afford to expend valuable energy to show you how strong and robust I am compared with the other gazelles.” I always thought that high jumps of savannah herbivores is meant to give them better view of predators, especially in tall vegetation.
