The life expectancy of the Desert kangaroo rats in the wild in unknown, but those in captivity usually live 5.5 - 8 years. animalia.bio. Feeding Ecology & Diet. Young are born naked and with thin, pink, transparent skin. Wallabies and kangaroos cannot be housetrained, nor should th… They eat grasses, flowers, leaves, ferns, moss and even insects. Rather, they obtain water through metabolic processes augmented by the moisture content of their food. The fur lining stops the kangaroo rats food from losing water in transit. The kangaroo rat's body is extremely efficient at processing food, using very little water in elimination of waste. Although they are desert dwellers, most species are good swimmers. They collect seeds in their cheek pouches, and store them in underground burrows for later eating. D. microps can survive on these leaves in the laboratory without other food or water, but it is unusual among kangaroo rats in that it quickly succumbs when placed on a diet of air-dried seeds without water or succulent plant material. Kangaroo rats live in burrows by day, foraging by night for seeds, leaves and other vegetation, and carrying food in their cheek pouches to store in their underground homes. 500 x 359 jpeg 66kB . THE KANGAROO RAT Dipodomys merriami is one of a number of mammalian species that are known to concentrate their urine to more than 6,000 mosmol/kgH 2O (5), nearly twice as high as that of the laboratory rat. The role of Desert kangaroo rats in the local ecosystem is not fully explored. The remainder of their diet consists of other plant materials. Mating season lasts from early January to early July. The species is so called due to hopping like a kangaroo. They can, however, vary in both geographic range and habitat. It is one of the large kangaroo rats, with a total length greater than 12 inches (30 cm) and a mass greater than 3.2oz (91g). Various species of Kangaroos have been discovered. Nasal passages of kangaroo rats possess a special cooling system, which reduces loss of moisture and helps the animals cool off. Likewise, they eat different things. Because of its nocturnal behaviour and by living in cool underground areas during the day they do not lose much water unless forced to have a diet low in carbohydrates. Kangaroo rats' primary food is seeds -- mesquite, creosote bush, purslane, ocotillo, and grama grass have been found in their cheek pouches. They have large heads with big eyes and small ears. Diet . The kangaroo rat does not sweat, meaning it conserves water. Typical types of food include leaves of sage and various seeds such as these of the creosote bush. They will, however, sometimes eat vegetation at some times of the year and some insects, too. The Desert kangaroo rats are adorable animals with noticeably large hind legs, helping them escape from predators. They tend to live in arid, open areas and only go out at night when the temperatures are cooler. However, all of them are herbivores – means they eat only vegetative materials. For the purpose of this article, whenever kangaroos are mentioned it will only be in reference to the four species stated above. Kangaroo rats have long tails and big hind feet with four toes. Kangaroo rats will store extra seeds in seed caches. They are very territorial with only one adult per burrow. These animals are solitary, socializing only when mating or rearing their young. Hence, the mother kicks sand onto her babies in order to dry them. This kicking habit allows them to escape traps: they usually kick so much sand onto traps that eventually spring or bury them. Desert kangaroo rats are herbivores (folivores). The smaller species of kangaroos are found to eat underground fungi. Although the mating system of this species is unknown, Desert kangaroo rats are thought to be polygynandrous (promiscuous), which means that individuals of both sexes mate with multiple mates. Kangaroo rats are mouse-sized rodents native to the southwest United States and Mexico. 750 x 600 jpeg 666kB. The unusual Desert kangaroo rat is among the animals with least water demand. Kangaroo rats are the archetypical organisms for mammalian survival in North American deserts, yet there are contradictions in the data surrounding their physiology and ecology. 864 x 576 jpeg 142kB. - Ord's kangaroo rats are primarily granivores, with around 75% of their diet made up by seeds. Due to the kind of habitat they live in, the diet of kangaroo rats is fairly limited but very specialised to their dietary needs and nutrition. Kangaroo rats live in burrows underground which they dig out of the soft, dry sand, usually at the base of bushes. Whereas, red-kangaroos also eat nearby shrubs.
