駱駝的皮膚上有汗腺利用水的蒸發散熱，像人類一樣，然而，駱駝皮也被厚厚的毛皮覆蓋—-有些地方有十公分左右的深度。不過他的毛皮並不會妨礙水的蒸發。其主要的作用是使駱駝免受傳入的熱量。
(Camels have sweat glands distributed throughout their skin, from which water removes body heat through evaporation, much as in humans. However, camel skin is also covered by thick fur––4 inches (10 cm) deep in places. This fur doesn’t impede the evaporation of water though. What it does do is insulate the camel from incomingheat.)
