Merriam's kangaroo rats obtain enough water from the metabolic oxidation of the seeds they eat to survive and do not need to drink water at all. [11] To help conserve water they produce very concentrated urine, via a process apparently associated with expression of aquaporin 1 along a longer than usual segment of the descending limb of the loop ...
Merriam's kangaroo rat (Dipodomys merriami) is a species of rodent in the family Heteromyidae. [2] The species name commemorates Clinton Hart Merriam . It is found in the Upper and Lower Sonoran life zones of the southwestern United States , Baja California , and northern Mexico .
A single Ord's kangaroo rat may make tens to hundreds of caches, each with tens to hundreds of seeds. [33] Kangaroo rats are physiologically adapted to arid environments. Most water is obtained from seeds and succulent plants. They drink water when it is available, but apparently do not require free water. [19] [34]
Most animal feces are over 75% water; xerocoles, however, reabsorb water in the gut and produce much drier feces. [21] For example, the kangaroo rat's feces contain only 1 ⁄ 6 as much water as that of other, non-desert rodents. [22] In insects, the rectal gland also absorbs water, and the insects excrete dry pellets. [21]
The kangaroo rats, kangaroo mice and pocket mice are adapted for life in deserts and other arid environments where they largely feed on dry seeds. Kangaroo rats have no need to drink because they are able to extract sufficient water from metabolising their food, obtaining half a gram of water from each gram of seeds eaten.
Many folks opt to aim for the nice, square number of 1 gallon of water a day (for reference, 2.7 liters equal about 0.7 gallons), so we looked into the health benefits of drinking that much H20 ...

Phillips's kangaroo rat (Dipodomys phillipsii) is a species of rodent in the family Heteromyidae. [3] It is endemic to Mexico.Its natural habitat is hot deserts. The species is named after John Phillips, an official of a Mexican mining company who sent zoological specimens, including the type specimen of this kangaroo rat, to the British Museum.
