At very high temperatures and constant heat loads even camels need to dissipate heat.
Many mammals achieve evaporative cooling through an increased respiratory rate rather
than by sweating. Respiratory cooling is relatively more expensive in water than is
sweating since faster respiration rates result in more energy being used. Normal
respiratory rates in camels are in the range of 6 to 11 breaths/min. (average 8) in the
Sahara. Under heat stress these increase to levels of 8 to 18 (average 16). Such low
respiration rates do not result in significantly increased evaporation. ...
