The camel's eyes are protected from blowing sand and dust by a double row of eyelashes. Dromedaries are able to conserve water in a variety of ways. Water is conserved by the camel's ability to fluctuate its body temperature throughout the day from 34 degrees Celsius to 41.7 degrees Celsius. The fluctuation in body temperature allows the camel to conserve water by not sweating as the external temperature rises. Groups of camels also avoid the excess heat from the environment by pressing against each other.
Water is expended primarily from interstitial and intracellular bodily fluids.
Furthermore, dromedaries can rehydrate quickly, being capable of drinking 100 L of water in just 10 minutes, a feat which would be lethal to any other mammals. The dromedary camel is no longer considered a wild animal. The camel is a semi-domesticated animal, freely ranging, but under herdsman control. The earliest evidence for dromedary domestication dates back about 4,000 years ago on a small island off the Abu Dhabi coast. Northern Arabian tribes began to use the dromedary as a riding animal around 3,100 years ago.
