Tanezrouft in Sahara desert has one of the most harshest climates in the world, wind, sand storms and dust devils. Camels are amazing animals, inspite the dry lifeless desert and days without water, they can survive quite a long time that almost no other animal could. In one drink they can drink from 100 to 150 liters of water. In the picture we can se two single-humbed camels walking through the lonely desert. On the picture you can also see a mirage that appears often in such landscapes.
