Animals have also created some strategies to preserve water and avoid hot weather: thick skin and underground life for scorpions and insects, recuperation of water steam in pulmonary air by condensing it in nostrils, production of drained faeces and concentrated urine for some birds, loss of sudoriferous glands, clear colored skin to reflect the sun, search for water and food at night, accumulation of water in internal pockets, large ears to regulate calorific waste ( fennecs, sand cats), short hairs for better thermolysis, increase of internal temperature to avoid perspiration…
The emblematic animals of the desert are addaxes, gazelles, doncas and fennecs.
Camels are the main animal of the desert. Without them, humans could not have lived in the Sahara. They have a great capacity to resist heat and thirst. Even above 50°, they can stay without drinking water for many days. Camels can carry about 250 kg of commodities between two distant places.
