Kangaroo is a cute little mammal from the family Heteromyidae living in the western hemisphere of the United States. Until the 1950s, native kangaroos were in danger of extinction. They mainly live in California. Kangaroo rats are a kind of nighttime mammals hiding in excuses during a hot day and when they prepare for the evening they use loose soil to block excuses (3). Their meal is to eat seeds and grains, the average life expectancy is 8 years. They are about 6 to 8 inches and the tail is 7 to 8.5 inches (1) in length.
The kangaroo rat sleeps in the cave deep underground to survive on a hot day, and it gets cooler at night. Kangaroo rats eat seeds of creosote, shrub, parsley, okotiro and grammar grass. They save the seeds on their cheeks and save the additional seeds in the seed cache. When the food source is high, Kangaroo rats will be stored as much as possible. The other difference is that desert fauna is cold-blooded and most tundra animals are warm-blooded animals. Animals living in Tundra adapt to low food and low temperature. Animals living in the desert adapt to the hot weather of the day. Many of them are activities during the night, only active during the night, few animals during the day. Desert animals are fighting more than tundra inhabitants
The desert provides a harsh environment where only a few mammals can adapt. Of these strong creatures, kangaroos are probably the most attractive. Since I can live in some of the most dry places in the Southwest, kangaroo can not cool their pants with sweat. Its specialized kidney allows it to survive with very little water. Unlike other desert creatures, kangaroos do not save water in their bodies, instead they convert dried seeds to moisture. It adapts to this harsh environment and makes kangaroos a truly wonderful creature
The size and characteristics of Kangaroo are very different. There are rock kangaroos with cave kangaroo kangaroos, back pockets and shortened wood kangaroos with very long tails, handfuls, granular foot pads for bantam and quarka. The biggest species are gray (or forest) kangaroos and red kangaroos. These two men may be more than 2.4 m (8 ft) away from the nose to the tail. Koalas are indigenous people's words, they do not drink these animals when they get sick but mean "do not drink". Koala is a tree-planting mushrooms that 14 to 15 eucalyptus trees inhabit. Trees become favorite animals. They eat specific eucalyptus leaves and supply enough moisture. Especially long bowel and special liver mechanisms to cope with rough oil of leaves and tannins
