The watchman

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.
