The desert fox, or Fennec Fox, has large ears, which, obviously, allows it to hear exceptionally well, but also serves to dissipate heat.

Simply the fact that it's nocturnal helps it to survive, as it spends the day seeking shade and staying in it rather than hunting or foraging for herbivorous food sources. This is fun.wiki.answers.com»
