Like many Death Valley residents, the kangaroo rat lives for the nightlife. It spends most of its day napping underground, only venturing out after sunset. Of course, taking advantage of the cool nighttime temps is a common trick among desert mammals. What's not common is how the kangaroo rat has adapted to deal with the scarcity of water: It never drinks the stuff! Special organs inside its nose allow it to absorb moisture directly from the air, and highly efficient kidneys keep its body hydrated. In fact, the kangaroo rat is so well adapted to the dry climate that even after living in captivity for years, it will still refuse water.
What else can I help you with?
When does a kangaroo rat drink water?
Kangaroo rats cannot live without moisture, but they can live without drinking water. Kangaroo rats are specially adapted for the desert conditions in which they live, and they can therefore obtain all their moisture needs from the food they eat.
What animal in the desert lives by getting it water out of its food?
In North America the various species of kangaroo rat are able to extract all the water they need from the plants and seeds they eat.
What adaptations does a kangaroo rat have to help it survive?
A primary adaptation of kangaroo rats is that they seldom drink water. They obtain most of their water needs from seeds and plants that they eat. In order to survive the heat and dryness of their environment, kangaroo rats burrow into the dirt, in order to take away the top layer, which is heated by the Sun, to get to the cool dirt underneath. They also obtain most of their moisture needs from the food they eat, and do not need to take in extra water. Kangaroo rats have well developed hind legs. The animal uses its legs to escape from predators, and they are able to leap very high, despite their small size. The kangaroo rat's fur matches the colour of the sand and rocks where it lives in the deserts of the Southwestern US and this helps it to camouflage from predators.
Does a kangaroo rat get water from food so it does not need to drink?
Correct. The kangaroo rat (which, incidentally, is a quite different species to the rat-kangaroo of Australia) drink water very rarely. They are able to obtain most of their moisture needs from the food they eat. They also have a very water-efficient metabolism which inhibits moisture loss from their bodies.
What must organisms be able to obtain in order to surive?
They must obtain food,shelter,and water
How much of the total water gain does the kangaroo rat get from metabolic water?
Total water weight gain from metabolic water for the kangaroo rat is normally double its bodyweight. The rat doubles in size, registers as a democrat, and is then able to vote in the next election.
What characteristics of fruits and seeds dispersed by water and wind?
Water: Husk as covering Able to float on water

What desert animal can live without water?

Why Can a staminate flower not produce seeds?
because it is not able to reach the water and soil
Does the amount of water affect the germination of bean seeds?
If the amount of water is to great around the bean seed it will die and not be able to germinate.
How do cnidarians obtain oxygen?
Cnidarians are able to absorb the oxygen they need from the surrounding water by diffusion.
