Like most [G 45 / ungulates], the wildebeest's eyesight is excellent in the daylight and is particularly well adapted for detecting predators on the flat expanses of the coverless plains. Its elongated pupils and highly sensitive retinas detect the slightest movement and allows the animal to accurately judge distance and speed.
