Cerastes cerastes is a venomous viper species native to the deserts of Northern Africa and parts of the Middle East. They often are easily recognized by the presence of a pair of supraocular horns, although hornless individuals do occur.
Arid north Africa (Morocco, Western Sahara, Mauritania and Mali,
eastward through Algeria, Tunisia, Niger, Libya and Chad to Egypt,
Sudan, Ethiopia and Somalia) through Sinai to the northern Negev of
Israel. In the Arabian Peninsula, it occurs in Yemen and extreme
southwestern Saudi Arabia, where it is sympatric with C. gaperettii. A
report of this species being found in Lebanon is unlikely, according
to Joger (1984). ~
