Overview
The Saharan Sand Viper is a highly recognizable desert specialist found across the vast Sahara and into the Arabian Peninsula. Many individuals bear a pair of small, pointed horn-like scales above the eyes, though hornless forms also occur.
It is well known culturally, having appeared in ancient Egyptian art, and remains a common sight in arid regions where it is superbly camouflaged against sand.
