The Thomson's gazelle is a small, agile antelope found primarily in the grasslands and savannas of East Africa. It is known for its distinctive black stripe along its sides and its graceful leaps, which help it evade predators. Adult Thomson's gazelles typically weigh between 40 to 60 pounds and stand about 2 to 3 feet tall at the shoulder. These gazelles are social animals, often seen in herds that can range from a few individuals to several hundred. They primarily feed on grasses and are known for their incredible speed, capable of running up to 50 miles per hour to escape threats from predators like lions and cheetahs.
