The Berg adder (Bitis atropos) is a small venomous snake, with triangular head. It is found in isolated areas in the mountain regions of Zimbabwe and the Cedarberg in the southwestern Cape, South Africa. Although it is aggressive and strikes readily, its cytotoxic venom, in most of the cases, is not fatal, despite its painful bite.
