The meerkat is a small diurnal herpestid (mongoose) weighing on average about 731 grams (1.61 lb) for males and 720 grams (1.6 lb) for females. Its long slender body and limbs give it a body length of 25 to 35 centimetres (9.8 to 14 in) and an added tail length of 17 to 25 centimetres (6.7 to 9.8 in). Its tail is not bushy like all other mongoose species, but is rather long and thin and tapers to a black or reddish colored pointed tip. The meerkat uses its tail to balance when standing upright, as well as for signaling. Its face tapers, coming to a point at the nose, which is brown. The eyes always have black patches around them and it has small black crescent-shaped ears that can close to exclude soil when digging. Like cats, meerkats have binocular vision, a large peripheral range, depth perception, and eyes on the front of their faces.
Meerkat live in all parts of the Kalahari Desert in Botswana, in much of the Namib Desert in Namibia and southwestern Angola, and in South Africa.
