Camel

• The camel can go as long as six months without consuming water. This is possible with the camel's ability to alter its own body temperature during intense heat. Also, the camel's thick skin insulates it from extreme heat. Therefore, a camel does not use water to sweat during hot days, since it retains water while changing its own body temperature.
  
  

Kangaroo Rat

• The San Bernardino kangaroo rat, inhabiting the desert climates of San Bernardino and Riverside counties in California, can live almost indefinitely without water. It is able to metabolically acquire moisture and water via the consumption of vegetation and dry seeds, according to the California Department of Pesticide Regulation.
  
  

Desert Toads

• Desert toads tend to lay dormant in shady areas through a large portion of the year until the summer rain creates ponds. When they return from their shady hibernation, they replenish their internal water and food supply and go without consumption for another long period. Desert toads also retain water by burrowing in wet soil during intense heat.
  
  

Turkey Vulture

• Turkey vultures metabolize and excrete wastes in in the form of uric acid, which requires very little water and thus allows them to retain lots of water for longer periods of time. Similarly with the kangaroo rat, turkey vultures also obtain moisture and water from eating their pray.
