Antelope Escaped From Hungry Lions

The Saiga Antelope is hunted for its horns, which are considered an aphrodisiac by some cultures. Only the males carry the horns, and have been heavily hunted to the point where some herds contain up to 800 females and a single male. The species has shown a steep decline and is critically endangered.
Lifespan
It is difficult to determine how long antelope live in the wild. With the preference of predators towards old and infirm individuals which can no longer sustain peak speeds, few wild prey-animals live as long as their biological potential. In captivity, wildebeest have lived beyond 20 years old, and impalas have reached their late teens. In the wild, few individuals of prey species live to old age, as the old and weak are easier prey for predators; antelopes are no exception to this rule.
