Meerkats are a type of Mongoose that live in the deserts of Sub-Saharan Africa in groups of between 20 and 50 know as a "mob", "gang" or "clan". They are known for standing on their hind legs which they do to expose a patch of sparsely cover skin on their belly to the heat of the sun.
They are very social living together in underground networks controlled by an alpha pair. When the group is playing or searching for food one Meerkat will perform sentry duty watching for predators and giving a warning bark if danger is spotted. Another Meerkat will take over after about an hour.
With no excess body fat store Meerkats must forage for food every day so have a wide ranging diet which includes insects, lizards, snakes, scorpions (they are immune to the venom), spiders, plants, eggs, small mammals, millipedes, centipedes and, occasionally, small birds.
