A Knysna dwarf chameleon (Bradypodion damaranum).
Issue Image

Male South African dwarf chameleons signal their dominance with conspicuous colours, emphasised during displays. The photo shows a Knysna dwarf chameleon (Bradypodion damaranum) displaying a combination of visible greens and ultraviolet greens, which appear similar to the human eye but very different to chameleons (see Stuart-Fox and Moussalli, page e25).
