Large animals that inhabit the dese

Large animals that inhabit the desert have evolved a number of adaptations for reducing the
effects of extreme heat. One adaptation is to be light in color, and to reflect rather than absorb
the Sun's rays. Desert mammals also depart from the normal mammalian practice of maintaini
ng a
constant body temperature. Instead of trying to keep down the body temperature deep inside
the body, which would involve the expenditure of water and energy, desert mammals allow their
temperatures to rise to what would normally be fever height, and temperatures as high as 46
degrees Celsius have been measured in Grant's gazelles. The overheated body then cools
down during the cold desert night, and indeed the temperature may fall unusually low by dawn,
as   low as 34 degrees Celsius in the camel. This is an advantage since the heat of the first few
hours of daylight is absorbed in warming up the body, and an excessive buildup of heat does
not begin until well into the day.

Another strategy of large desert animals is to tolerate the loss of body water to a point that
would be fatal for non-adapted animals. The camel can lose up to 30 percent of its body weight
as water without harm to itself, whereas human beings die after losing only 12 to 13 percent of
their body weight. An equally important adaptation is the ability to replenish this water loss at
one drink. Desert animals can drink prodigious volumes in a short time, and camels have been
known to imbibe over 100 liters in a few minutes. A very dehydrated person, on the other hand,
cannot drink enough water to rehydrate at one session, because the human stomach is not
sufficiently big and because a too rapid dilution of the body fluids causes death from water
intoxication. The tolerance of water loss is of obvious advantage in the desert, as animals do
