The meerkat is a small diurnal herpestid (mongoose) weighing on average about 0.5 to 2.5 kilograms (1.1 to 5.5 lb). Its long slender body and limbs give it a body length of 35 to 50 centimetres (14 to 20 in) and an added tail length of around 25 centimetres (9.8 in). The meerkat uses its tail to balance when standing upright, as well as for signaling.
The blesbok or blesbuck is an antelope endemic to South Africa. It has a distinctive white face and forehead which inspired the name, because bles is the Afrikaans word for a blaze such as one might see on the forehead of a horse.
