Pachydactylus rangei
''Pachydactylus rangei'', the Namib sand gecko or web-footed gecko, is a species of small lizard in the family Gekkonidae. It inhabits the arid areas of Angola and Namibia and was first described in 1908 by Swedish zoologist L.G. Andersson, who named it after its finder, German geologist Dr. Paul Range.〔〔Beolens B, Watkins M, Grayson M. 2011. ''The Eponym Dictionary of Reptiles''.

==Description==
''Pachydactylus rangei'' grows to a length of about including a tail. The head is quite distinct from the slender body and both are flattened dorsally. The eyes are large, dark-coloured and protuberant and have vertical pupils.The Web-footed gecko is very pale, nearly translucent. It has a salmon-colored undertone and some have light brown stripes or patterns. The coloring of their skin allows for very good camouflage among the sand of the Namib Desert.〔(【引用サイトリンク】title=Web-Footed Gecko )〕 The skin is covered in fine, smooth scales and is translucent, and some of the internal organs can be seen through it. The legs are thin but the feet are broad, with fully webbed toes, enabling this gecko to burrow easily and to run on loose sand. The gecko developed the webbed feet as an adaptation to help them stay on top of the Namib Desert sand or bury underneath the sand.〔 They have developed this adaptation due to being nocturnal and needing to spend the days in self dug burrows and then spend the night on top of the sand feeding. Their feet also have adhesive pads on the bottom to help them climb.〔 The tail is thicker in males. The females can weigh around 10 grams and the males about 6 grams.〔(【引用サイトリンク】title=Ecology Care and Breeding of the Namib Web Footed Gecko - Gecko Time )〕 The head and dorsal surface are pinkish-brown with darker markings, particularly in two intermittent lateral lines, and the ventral surface is off-white. There is often a bluish band between the eyes. This species is rather similar in appearance to ''Ptenopus garrulus'', another species of gecko found within its range.〔(【引用サイトリンク】title=''Pachydactylus rangei'' Andersson, 1908 )〕
