They range across most of central Africa down into South Africa including Ethiopia, Kenya, Congo, Angola and Namibia. You can find 12 different species of Agama in South Africa and inhabiting the North of the country, Acanthocercus Atricollis being one of these.
Normally a male displaying his colours won’t be far away from several females. These lizards tend to live in colonies with one dominant male and a group of females and other subordinate males.
