Psammophis schokari
(Sand snake)
Sand snakes are relatively abundant in all parts of the desert, both in areas with and without vegetation. The most were noted in October 2003, when the weather was unseasonably hot. Two were seen in the lower dead branches of palm trees (at Bir Zighen and Kufra), others in the open desert. A particularly large individual (over 1 metre long) was seen basking in the morning sun in the bed of the north branch of Karkur Idriss.
