WATER CONSERVATION OF THE KANGAROO RAT, DIPODOMYS ORDII . Tubular fluid of the kangaroo rat DTL may approach osmotic equi- librium with interstitial fluid by water reabsorption along a relatively longer tubule length, compared with Munich-Wistar rat. The kangaroo rat (which, incidentally, is a quite different species to the rat-kangaroo of Australia) does drink water, but very little. This kangaroo rat (Dipodomys merriami) was found during a biological survey with Sacramento City College in May 2015. Read on to learn about the Kangaroo Rat.

The kangaroo rat, which lives in the desert of southeastern Arizona, is so good at conserving water that it doesn’t have to drink at all. This causes the moisture in the air to be absorbed by the seeds, and the kangaroo rat regains the water it has previously lost when it then consumes them. A relatively shorter-length prebend segment may promote a steeper reabsorptive driving force at the loop bend. Types of Water Loss.
