To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey(猎物), meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock,totally out of touch and destined to starve to death. by controlpanel hHQt4 r'd
So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier(憔悴的), it constructs a wider-meshed web using fewer strands(线). Such webs would only trap larger prey, which is more economical from the perspective of a starving spider. by controlpanel TW$^]u~v
The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactively,labeled materials, it was found that 95 percent of web protein reappears in the next day' web. Most of the energy needed for web-building is used in walking over the strands as they are laid down.by controlpanel Nsy.!,!c
Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate(无脊推动物).If web-building is interrupted, or if some of the existing strands are destroyed,the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another. by controlpanel ME"/%59r

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 maintaining 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. by controlpanel #Uo

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 not have to remain near a water hole but can obtain food from grazing sparse and far-flung pastures. Desert-adapted mammals have the further ability to feed normally when extremely dehydrated, it is a common experience in people that appetite is lost even under conditions of moderate thirst. by controlpanel Yd9y8TqJ
