The Sidewinding Adder (Bitis peringueyi) is found in the Namib Desert in Namibia and southern Angola. A small species adapted to living in the dunes, I saw this individual on a Living Desert Tour out of Swakopmund. Check out the videos of it sidewinding and burying itself in the sand. Even though they are in the viper family, their venom is not overly toxic and won’t kill a human. Being only 20-25cm (8-10”) long, they are one of the smallest vipers in the world. True to their common name, they sidewind along the dunes, minimally touching their bodies to avoid the hot desert sand. They are also unique in having their eyes nearly on top of their head, which enables them to bury themselves deep in the sand with just their eyes piercing the surface. Their diet consists mainly of lizards and geckos and it’s through this diet that they also receive enough moisture. From recent nature explorations of Namibia and Botswana.
