The Namaqua chameleon (Chamaeleo namaquensis) is one of the Namib’s most accessible and most photographed wildlife subjects, and most visitors to Sossusvlei drive straight past it without stopping. The animal is there: moving slowly across the gravel plains between Sesriem and Solitaire, hunting insects, navigating the temperature extremes of the desert through an extraordinary repertoire of behavioural and physiological adaptations. You just need to know where to look.
Finding Them
Where: The gravel plains on either side of the C19 road between Solitaire and Sesriem. Also on the gravel flats adjacent to the park road inside the gate, particularly in the early morning.
When: Midmorning, once temperatures have risen above approximately 20°C. Namaqua chameleons emerge when the air and ground have warmed enough to support activity. In cold months (June to July), this may be 08:30 to 09:00; in warm months, from approximately 07:00.
How: Drive slowly (below 20km/h) and scan the gravel surface ahead of the vehicle. The chameleon moves with a characteristic slow, deliberate rocking motion and is large enough to see from the vehicle at 10 to 15 metres. It does not hide effectively from a careful observer; it relies on camouflage (its colouring matches the gravel surface closely) and stillness.
Desert Survival
Colour change for temperature regulation: In the early morning, the chameleon darkens its skin to absorb maximum solar radiation and warm up quickly. As body temperature rises to the optimal range (approximately 34 to 38°C), the skin lightens to reflect radiation and maintain temperature.
Fog harvesting: On foggy mornings, Namaqua chameleons orientate their bodies perpendicular to the fog flow and allow droplets to condense on their skin. The droplets run toward the mouth and are licked up. This behaviour harvests atmospheric moisture without requiring free water.
Bipedal walking: To cross hot ground quickly, Namaqua chameleons sometimes walk on their hind legs with their front legs raised, reducing the contact between the feet and the hot surface.
Hunting: A sit-and-wait predator for insects and occasionally smaller lizards. The tongue extends to the body length in a fraction of a second; the target is struck with remarkable accuracy.
Fotografie
The Namaqua chameleon is an excellent photography subject: slow-moving, tolerant of close approach when not pressured, and visually compelling. A 100 to 200mm macro or telephoto lens from outside the vehicle works well. Do not touch or disturb the animal; simply position yourself quietly at ground level and allow it to resume normal behaviour. Colour change is most visible when the animal is slightly stressed; a relaxed animal in normal conditions will show its characteristic sandy-grey gravel camouflage.
