Kangaroo: Kangaroo Rat
built 199 days ago
Kangaroo Rats are solitary animals with a home range of less than one-half acre; the female's home territory is usually smaller than the males. They live in burrows they dig themselves. The burrows go into the ground at an angle, are 1.5 to 3 inches in diameter and shaped like an inverted U, though flat on the bottom.

This was not the last of the Killer Kangaroo. Killer Kangaroo won the downunder boxing championship, which was held against other kangaroos and other Australian mascots such as the emu, the wallaby, the platypuss, the crocodile, the stingray and Steve Irwin. The semifinals saw the Killer Kangaroo smashing the crocodile while the stingray killed Steve Irwin as he decided to make a documentary at that moment rather than fight. The stingray was disqualified from the tournament for using its tail as a weapon which automatically resulted in the Killer Kangaroo being declared the winner. Confident and determined, the Killer Kangaroo challenged the boxing legend Muhammed Ali into a duel and forced him into retirement after knocking out Ali in just 2 rounds. Critics argue that the Kangaroo had a home turf advantage, as the match was held downunder in scorching heat and in the middle of nowhere, with a dingo as the referee.

The female kangaroo rat has 3 or more litters of babies a year which are born from January through June. She is pregnant for 29 to 32 days. The newborns weigh about 1/16 oz (3 g). The babies are weaned at 3 to 4 weeks. Their life span in the wild is 3 to 5 years. They are solitary creatures, only one animal occupies a burrow, and have territories of about 1/2 acre.

Most Kangaroo Rats occupy sandy to rocky soils in desert locations with little vegetation. Their burrows enter the ground at an angle. Dsome prefer with well-developed grasslands and scattered with heavier to support the bannertails' complex burrow systems.

The only member of the kangaroo family that does not hop is the musky rat-kangaroo. Scientists have tried to learn why hopping is so widespread among kangaroos but is so rare in other mammals. Studies have shown that hopping is energy efficient for kangaroos, partly because of springlike tendons in their legs. The energy required to start hopping is quite high, but very little extra energy is needed to hop faster and faster. In contrast, mammals that run on all fours require increasing amounts of energy as speed increases.

Smaller, but quite similar in appearance and behavior, are members of the kangaroo family called wallabies and pademelons, of which there are many species, classified in several genera. Some of these are plains dwellers, others live among rocks or in scrub country; most are about the size of a rabbit. Of similar size are the tree and rat kangaroos. Tree kangaroos, species of the genus Dendrolagus, are the only arboreal members of the family. Found in the rain forests of New Guinea and N Australia, they climb well and can leap from branch to branch. Rat kangaroos are omnivorous animals of ratlike appearance.
