This is difficult to answer definitely, as there is so much variation.

In the wild, kangaroos live anything from 7-15 years on average with the smaller species having shorter life expectancies. In captivity, kangaroos can live upward of 20 years. Many wild kangaroos are killed on the road, and culling also occurs to control their numbers in certain areas.

Depending on the species, kangaroos can live anywhere between 12-15 years. Smaller species have a life span of less than ten years.

The scientific classification of the red kangaroo is as follows:

• Kingdom: Animalia
• Phylum: Chordata
• Class: Mammalia
• Order: Diprotodontia
• Family: Macropodidae
• Genus: Macropus
• Species: Macropus rufus

The noise made by a kangaroo can best be described as a sort of gentle tut-tut sound. When more aggressive, the noise increases to a louder grunting, and occasional hissing. Some people have reported territorial growling.

Of course, the thumping of a kangaroo in full flight is a distinctive sound as well. Its strong, heavy hind legs make a distinct "thud" as it moves through bushland, and other kangaroos will recognise the sound of their own kind in flight, and heed it as a warning, even from a distance.

The sand in Australia is red because of the large amount of iron oxide found in that sand. Australia is known for its dry climate and red sands.

Yes. Red kangaroos generally have just one joey at a time. However, it is not unusual for a female kangaroo to have two different aged joeys in her pouch at the same time. It is extremely unusual for a kangaroo to have more than one joey of the same age at any given time, but twins have been observed on rare occasions.

Not at all. Red kangaroos balance back on their strong tail, and use their powerful hind legs, which have sharp claws on them, to kick when then they fight. Human have neither a tail, nor sharp claws on powerful hind legs.

Red kangaroo numbers are not decreasing dramatically overall. Numbers of both the Red kangaroos and Bith Soecies of Grey kangaroos fluctuate widely from year to year, depending on whether or not there is a drought at that time. Red kangaroos are still plentiful, and after a couple of good seasons, their numbers can rise to plague proportions.

Kangaroos are very strong swimmers. In Australia's southern areas, they frequently commute from off-shore islands. Despite their apparently awkward shape, their powerful hind legs propel them along. However, it is not known how fast they can swim. Given that they can easily swim a kilometre or so, it can be assumed that they are not particularly slow swimmers.

Naturally, kangaroos use their mouth and their teeth. They also use their short forepaws to grasp vegetation.

Yes they are, they only have forlegs at birth.

Kangaroos are found all over the Australian continent, but their exact location depends on the species. There are over 60 species of kangaroos in Australia. They are most commonly found in bushland and woodland, open forests, coastal heath land, grasslands, mallee scrub, mulga scrub and other scrubland. They have adapted to a variety of temperatures around Australia and are usually found in sub tropical and temperate zones, while the Eastern Grey kangaroo can also be found in sub-Alpine regions.

Kangaroos gather in groups called mobs. Aboriginal and European Australians have spent centuries clearing open tracts of land and establishing water sources-both of which are boons to kangaroo populations.

Larger kangaroos do not live in the desert, as the food is too scarce. However, smaller, omnivorous varieties of the kangaroo family (often not recognised as kangaroos) do burrow in the desert and gain all their moisture needs from the insects and larvae they eat.

Most of the types of kangaroo prefer the grassland habitat in Australia. They graze on grasses and low vegetation in the early mornings and the evening while seeking shelter under trees during the middle of the day. Places where farmlands or plains meet the scrub are ideal for kangaroos.

Red kangaroos live in open grasslands, bushland, mulga and mallee scrublands, where there are some shade trees, and plenty of fresh grass and shoots. They can be found in all mainland Australian states, but tend to be inland, rather than near coastal areas. (Grey kangaroos are more likely to be found in coastal areas, and even swimming.)

Tree kangaroos are found in the rainforests of far northern Queensland and New Guinea. They are predominantly arboreal creatures which do venture to the ground regularly.

The Red Kangaroo is found throughout the interior of the continent - not the dry, sandy desert but in semi-arid desert areas - and on part of the Western Australian coast. The red kangaroo lives in a much drier, hot climate than the Grey kangaroos. It prefers temperate areas, but is not found in the tropical regions of far north Australia.

Red kangaroos, being herbivores, do not need to catch food. They graze on stationary grass and vegetation.

It varies. In the eastern part of the range of the red kangaroo, females are likely to be more grey in colour, whilst elsewhere within their range both males and females tend to be reddish-brown.

I have a Merriams Kangaroo Rat that I've had for over 7 years now. She is a female that I found in the wild as a pup. She has never had an encounter with any other K Rats and she still seems very healthy.

Australia does not have the kangaroo or emu as its emblem, as it does not have an official faunal emblem, only a national floral emblem. However, the kangaroo and emu were adopted as part of the Australian coat-of-arms in 1908.

No. The Red kangaroo is a herbivore. Some of the smaller species of kangaroos, such as the Musky rat-kangaroo, are omnivores, but the Red Kangaroo is not.

Red kangaroos are not at all endangered. Since protection laws came into place last century, they have seen a resurgence in their population. Kangaroos are classified as 'Least Concern' by the IUCN.

There are about 60 different species of kangaroo in Australia, and they each have unique adaptations for different ecosystems and climates. Different species can live in all parts of Australia. Kangaroos live in a variety oftemperatures ranging from sub-Alpine to savanna grassland to temperate bushland and coastal heath. Some varieties of kangaroos seem to enjoy swimming, whilst others are just as happy in the dry mulga scrub. Tree kangaroos live in the tropical rainforest where temperatures are higher, along with the humidity.

Many larger species of kangaroos such as the red kangaroo, commonly said to live in the desert, cannot survive in the sandy desert at all. There is insufficient food or water for them to survive. However, they can certainly live in hot semi-arid areas where there are permanent waterholes, and where the vegetation is soft and juicy enough for them to eat.

The Red Kangaroo is found throughout the interior of the Australian continent - not the dry desert but in semi-arid desert areas - and on part of the Western Australian coast.

No, female red kangaroos are not blue.

In the eastern part of the red kangaroo's range, females are likely to be more grey in colour (not blue), whilst elsewhere within their range both males and females tend to be reddish-brown.

Red Kangaroos are the largest of the marsupials. The male Red Kangaroo averages 1.6 metres tall. Accounts of sizes greater than this are not uncommon, with some large males reportedly reaching approximately 2 metres (6.6 ft).

The weight of a red kangaroo can range from 18kg up to 90 kilograms for very large specimens. The male is heavier, and tends to weigh an average of 65 kg.

Females tend not to exceed 30 kg.

No. Rodents are placental mammals and kangaroos are marsupials. The two are not even remotely related.

Confusion can arise from the fact that there are kangaroo rats, which are rodents of North America, and rat-kangaroos which are marsupials, and members of the kangaroo family in Australia.
