Page "Antelope" Paragraph 30

Open grassland species have no where to hide from predators, so they tend to be fast runners.

They are agile and have good endurance — these are advantages when pursued by sprint-dependent predators such as cheetah, which are the fastest of land animals, but tire quickly.

Reaction distances vary with predator species and predator behaviour.

For example, gazelles may not flee from a lion until it is closer than 200 m ( 650 ft )— lions hunt as a pride or by surprise, usually by stalking ; one that can be seen clearly is unlikely to attack.

However, sprint-dependent cheetahs will cause gazelles to flee at a range of over 800 m ( 0. 5 mile ).
