A close-up of a male Thomson's gazelle: males have horns that are thicker and longer than those of the female. Thomson's gazelle is a relatively small gazelle; it stands 60–70 cm (24–28 in) at the shoulder. Males weigh 20–35 kg (44–77 lb), while the slightly lighter females weigh 15–25 kg (33–55 lb).
The Grant's gazelle looks similar to a Thomson's gazelle, except it is much larger and has lyre-shaped horns which are stout at the base, clearly ringed, and measuring 45–81 cm (18–32 in) long. A useful field mark is the white on the rump that extends over the top of the tail in Grant's but not Thomson's gazelles.
Bovids range in size from the 38 cm (15 in) long royal antelope to the 3.3 m (11 ft) long gaur, which can reach 1,500 kg (3,300 lb) in weight. [1] Over a billion each of domesticated sheep , cattle , and goats , and over 200 million domesticated water buffalo , 14 million domestic yak , and 300,000 domesticated gayal are used in farming worldwide.
In A. m. marsupialis, females have thinner horns than males; the horns of females are only 60 to 70% as long as those of males. Horns have a girth of 71–83 mm (2.8–3.3 in) at the base; this thins to 56–65 mm (2.2–2.6 in) towards the tip. In the other two subspecies, horns of both sexes are nearly similar.
Close view of a male, with characteristic lyre-shaped horns, white tail and several black markings. The impala is a medium-sized, slender-bodied antelope, comparable to the kob, puku and Grant's gazelle in size and build. [17] The head-and-body length is around 130 centimetres (51 in). [18]
The red-fronted gazelle gives birth to one fawn after a gestation period of 184–189 days. The fawn is likely to wean at around three months. Based on the closely related Thomson's gazelle, females may breed as early as nine months, while males may not mature until 18 months. [9] The lifespan is up to 14.5 years in captivity.
Horns of the male Mongalla gazelle are shorter and curved more inwards than those of the male Thomson's gazelle. [8] In 1969, Groves pointed out that the Mongalla gazelle is somewhat intermediate between the Thomson's gazelle and the Nubian red-fronted gazelle (E. r. laevipes). The size of the Mongalla gazelle is similar to the latter, but the ...
They have a territorial male as a leader in herds and sometimes group with other species, such as Grant's gazelle joining with Thomson's gazelle. [1] They can reach top speeds of 50 miles per hour (80 km/h) and have the ability to jump and turn sharply. They have adapted well to running in open environments. [2]
