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 ...
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.
Kangaroo rats lose water mainly by evaporation during gas exchange, and so have developed a behavioural adaptation to prevent this loss. As they spend a lot of time within their burrows to escape the heat of the day, the burrows become much more humid than the air outside (due to evaporative loss).
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]
The Santa Cruz kangaroo rat, more closely related to chipmunks and gophers than kangaroos or rats, had not been spotted in the area since the 1940s. The Santa Cruz kangaroo rat, more closely ...
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.
Dipodomys ornatus, commonly known as the ornate kangaroo rat or plateau kangaroo rat, is a species of kangaroo rat in the family Heteromyidae.Found in Mexico, Dipodmys ornatus was originally thought to be a subspecies of Phillips's kangaroo rat, D. phillipsi, and was described as such in 1894 by Clinton Hart Merriam.
