There are around 200 species of Tok tokkie beetles in Namibia, but the fog-basking variety that is endemic to the Namib is particularly noteworthy for its desert adaptations. When the cool moist wind blows off the Atlantic in the early mornings these beetles stand on dune crests, facing the breeze with their bodies angled up into the air. The hydrophilic surface on its back causes the fog to condense into water droplets, and once they combine to reach a diameter of 5mm or so in size, the whole drop breaks the static attraction to the back and rolls down the body and into the mouthparts of the beetle.
