Grant's gazelles are native to Eastern Africa, particularly found in countries like Kenya, Tanzania, and Ethiopia. They inhabit open grasslands, savannas, and semi-arid areas, preferring regions with a mix of grass and shrubs. Grant's gazelles are medium-sized antelopes, with males standing around 3.5-4 feet tall at the shoulder and weighing between 80 to 200 pounds. They have a light tan to reddish-brown coat, with a white belly and rump. Both males and females have long, curved horns. Their long legs and slender bodies make them agile runners, allowing them to reach speeds of up to 50 miles per hour to escape from predators. They have excellent eyesight to spot danger from afar.

Gazelles are herbivores, primarily feeding on grasses, leaves, and herbs found in their habitat.

Female gazelles give birth to a single calf after a gestation period of around 5-6 months. Calves are born with a camouflaged coat and can stand and walk soon after birth. Grant's gazelles are most active during the day, particularly in the early morning and late afternoon. They often live in herds for protection, but sometimes males prefer to live alone. When threatened, they use their speed and agility to evade predators.

Grant's gazelles are not considered endangered. However, they can face habitat loss due to human activities and competition with domestic livestock. Conservation efforts focus on maintaining their habitats and addressing potential threats.
