Kangaroo Rats
Water is an essential for the survival of humans. Without it, we cannot stay alive for a long time. However kangaroo rats have a unique ability to stay without water for years, almost their entire lifetimes. These fascinating creatures are found in the deserts of North America and are 8 to 14cm long with a large head, short forelimbs, long hind limbs. Their tail is as long as their body, and they spend most of their time in burrows to avoid sweating. They have a pouch on their cheeks to avoid store sweating.
Kangaroo rats search for food only when the temperature falls, which usually happens in the evening or at night. They eat seeds, leaves and other vegetation growing around them and the water that is needed for their body is received through the food they eat.
Interestingly, Kangaroo rats have larger kidneys compared to other rat species. Kidneys help in taking out the waste from the blood and transforming it into urine. Also, kidneys remove the extra water from their waste and pump it back into their body, thus allowing them to survive without drinking water for an extended period.
