African puff adder

Description:

The average size is about 1 m (39.3 inches) in total length (body + tail) and very stout. Large specimens of 190 cm (75 in) total length, weighing over 6.0 kg (13.2 lbs) and with a girth of 40 cm (16 in) have been reported. Specimens from Saudi Arabia are not as large, usually no more than 80 cm (31 in) in total length. Males are usually larger than females and have relatively longer tails. The color pattern varies geographically. The 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. Iris color ranges from gold to silver-gray. 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 may be 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.

Habitat:

The puff adder is found in South Africa. To the north they are found to the south of Chad and Niger, where it has spread to the east and the west to the coast. In Saudi Arabia it is widespread. Habitat: Hot and dry areas, particularly deserts and semi-deserts, steppes and savannas are preferred. In the rainy season it also penetrates into human settlements. The puff adder avoids too wet and swampy habitats.
