Typically between 18 and 25 cm long, these are Africa's smallest carnivores. They takeover large termite mounds and dig larger exit holes -- so you know when they're around. They live in groups of up to 30 individuals, and are headed by a dominant couple, and specifically, a dominant female. This female makes decisions of when to move, when to defend territory, and when to feed.
They have a mutualistic relationship with hornbills for hunting. They'll hunt at the same time -- though they might eat slightly different things, they each observe each other for signals of birds of prey (eagles, hawks, etc), since both must avoid them.
They're pretty common, and you'll likely see them scurry frantically if you ever are camping in sub-saharan Africa.
