Namaqua Dwarf Adder
This is the smallest adder in the world, averaging around 15-20 cm in length. It occurs in coastal dunes in Namaqualand and southern Namibia where it feeds on lizards and rain frogs. It is preyed upon by a variety of small carnivores and predatory birds as well as other snakes, but the biggest threat comes from habitat destruction, crossing roads and illegal collecting for the pet trade.
