The "Thomson's gazelle" is one of the best-known gazelles. It is named after explorer Joseph Thomson and is sometimes referred to as a ""tommie"". It is considered by some to be a subspecies of the red-fronted gazelle and was formerly considered a member of the genus "Gazella" within the subgenus "Eudorcas", before "Eudorcas" was elevated to genus status. Thomson's gazelles can be found in numbers exceeding 550,000 in Africa and are recognized as the most common type of gazelle in East Africa. Thomson's gazelles are 55 to tall, body length of 80 to, and weigh 15 to , 20 to . They have light brown coats with white underparts and distinctive black stripes on the sides. Their horns are long and pointed with slight curvature. The white patch on their rumps extends to underneath the tail, but no further. Grant's gazelles are sometimes mistaken for Thomson's gazelles. Although some Grant's do have the black stripe running across their sides, the white on their rumps always extends above the tail. The Thomson's gazelle lives in Africa's savannas and grassland habitats, particularly the Serengeti region of Kenya and Tanzania. It has narrow habitat preferences, preferring short grassland with dry, sturdy foundation. It does, however, migrate into tall grassland and dense woodland. Gazelles are mixed feeders. In the wet seasons, they eat mainly fresh grasses, but during the dry seasons, they eat more browse, particularly foliage from bushes, forbs, and clovers. Thomson's gazelles are dependent on short grass. Their numbers are highly concentrated at the beginning of the rains since the grass grows quickly. They follow the larger herbivores, such as plains zebras and blue wildebeests as they mow down the tall grasses. Then, the gazelles spread out more. In the wild, Thomson's gazelles can live 10–15 years. Their major predators are Tanzanian cheetahs, which are able to attain higher speeds, but gazelles can outlast them in long chases and are able to make turns more speedily. This small antelope-gazelle can run extremely fast, from 80 km/h, to 96 km/h and zigzag, a peculiarity which often saves it from predators. Sometimes they are also chased by leopards, lions and hyenas, but the gazelles are faster and more agile; these predators attack especially the young or infirm individuals. They can also be devoured by crocodiles and pythons, and their fawns are sometimes the prey of eagles, jackals, and baboons. A noticeable behaviour of Thomson's gazelles is their bounding leap, known as stotting or pronking, used to startle predators and display strength.
