Peringuey's adder / Sidewinding adder (Bitis peringueyi), Namib Desert, Namibia. This little endemic snake is one of the smallest adders in the world. This adder reaches a length of 30cm and has eyes on top of the head, which allows the snake to burrow under the sand and still keep its eyes out surveying the surroundings for prey. They move in a lovely sidewinding fashion, which allows them to move along the slip face of dunes where the sand is loose. Sidewinding also keeps most of the body off the sand at any given moment and allows the snake to move over hot sand without overheating. They are front fanged and have a combination of Cytotoxic and Neurotoxic poison. They give live birth (viviparous) and have up to 10 young during the summer months. A little black point on the tail is used to attract lizards closer to the snake while it lies below the surface of the sand out of sight.
