The Puff adder is a venomous viper species found in Namibia and on to Windhoek This snake is responsible for causing the most snakebite fatalities in Africa owing to various factors, such as its wide distribution, frequent occurrence in highly populated regions, and aggressive disposition. The color pattern of Puff adders varies geographically. Their head has two well-marked dark bands: one on the crown and the other between the eyes. On the sides of the head, there are two oblique dark bands or bars that run from the eye to the supralabials. Below, the head is yellowish-white with scattered dark blotches. Dorsally, the ground-color varies from straw yellow, to light brown, to orange or reddish-brown. This is overlaid with a pattern of 18-22 backwardly-directed, dark brown to black bands that extend down the back and tail. Usually, these bands are roughly chevron-shaped but maybe more U-shaped in some areas. They also form 2-6 light and dark cross-bands on the tail. Some populations are heavily flecked with brown and black, often obscuring other coloration, giving the animal a dusty-brown or blackish appearance. The belly is yellow or white, with a few scattered dark spots. Newborn young have golden head markings with pinkish to reddish ventral plates toward the lateral edges.
