Web-footed Gecko

The Web-footed Gecko, Pachydactulys (or Palmatogecko) rangei, inhabits the bleak and forbidding Namib Desert.  Yet, it is a tiny and delicate little thing!  It only measures about 13 cm/5" in length, and its skin and much of its body is translucent so that you can see its veins and arteries and even some of its organs!  And it has a real-life Eye of Sauron, with fiery red patches bordering the slit pupil.  The webbed toes helps it to get traction on the sand dunes, and to dig its burrows in which it stays by daytime, coming out to eat mostly at night.  It also has ridges on its toes that help them to cling to smooth surfaces, and it can easily climb up rocks in the rockier parts of the desert.   It is fairly closely related to geckos with much more normal toes.  Watercolour.
