As with the terms " wallaroo " and " wallaby ", "kangaroo" refers to a paraphyletic grouping of species.

All three refer to members of the same taxonomic family, Macropodidae, and are distinguished according to size. The largest species in the family are called "kangaroos" and the smallest are generally called "wallabies".

The term "wallaroos" refers to species of an intermediate size. A general idea of the relative size of these informal terms could be:. Kangaroos have large, powerful hind legs , large feet adapted for leaping, a long muscular tail for balance, and a small head.

Like most marsupials, female kangaroos have a pouch called a marsupium in which joeys complete postnatal development. The large kangaroos have adapted much better than the smaller macropods to land clearing for pastoral agriculture and habitat changes brought to the Australian landscape by humans.

Many of the smaller species are rare and endangered, while kangaroos are relatively plentiful. The kangaroo is a symbol of Australia , appears on the Australian coat of arms [4] and on some of its currency , [5] and is used as a logo for some of Australia's most well-known organisations, such as Qantas , [6] and as the roundel of the Royal Australian Air Force.

Wild kangaroos are shot for meat, leather hides , and to protect grazing land. The word kangaroo derives from the Guugu Yimithirr word gangurru , referring to eastern grey kangaroos.

Guugu Yimithirr is the language of the people of the area. A common myth about the kangaroo's English name is that it was a Guugu Yimithirr phrase for "I don't know" or "I don't understand".

They asked a nearby local what the creatures were called. Haviland in his research with the Guugu Yimithirr people was able to fully confirm the proper etymology.

Kangaroos are often colloquially referred to as "roos". In addition, there are about 50 smaller macropods closely related to the kangaroos in the family Macropodidae.

Kangaroos and other macropods share a common ancestor with the Phalangeridae from the Middle Miocene.

At this time, there was a radiation of macropodids characterised by enlarged body size and adaptation to the low quality grass diet with the development of foregut fermentation.

Some argue that the balbarines were the ancestors of rat-kangaroos and the bulungmayines were the ancestors of kangaroos. The middle to late bulungmayines, Ganguroo and Wanburoo lacked digit 1 of the hind foot and digits 2 and 3 were reduced and partly under the large digit 4, much like the modern kangaroo foot.

This would indicate that they were bipedal. In addition, their ankle bones had an articulation that would have prohibited much lateral movements, an adaptation for bipedal hopping.

The red kangaroo appears to be the most recently evolved kangaroo, with its fossil record not going back beyond the Pleistocene era, 1—2 mya.

The first glimpse of a kangaroo for many 18th-century Britons was a painting by George Stubbs. Kangaroos and wallabies belong to the same taxonomic family Macropodidae and often the same genera, but kangaroos are specifically categorised into the four largest species of the family.

The term wallaby is an informal designation generally used for any macropod that is smaller than a kangaroo or a wallaroo that has not been designated otherwise.

Kangaroos are the only large animals to use hopping as a means of locomotion. Seventy percent of potential energy is stored in the elastic tendons.

Both pentapedal walking and fast hopping are energetically costly. If pursued into the water, a kangaroo may use its forepaws to hold the predator underwater so as to drown it.

Kangaroos have single-chambered stomachs quite unlike those of cattle and sheep, which have four compartments. However, this is a different, more strenuous, activity than it is in ruminants , and does not take place as frequently.

Different species of kangaroos have different diets, although all are strict herbivores. The eastern grey kangaroo is predominantly a grazer , and eats a wide variety of grasses, whereas some other species such as the red kangaroo include significant amounts of shrubs in their diets.

Smaller species of kangaroos also consume hypogeal fungi. Many species are nocturnal , [37] and crepuscular , [38] [39] usually spending the hot days resting in shade, and the cool evenings, nights and mornings moving about and feeding.

Because of its grazing habits, the kangaroo has developed specialized teeth that are rare among mammals. Its incisors are able to crop grass close to the ground and its molars chop and grind the grass.

Since the two sides of the lower jaw are not joined or fused together, the lower incisors are farther apart, giving the kangaroo a wider bite.

The silica in grass is abrasive, so kangaroo molars are ground down and they actually move forward in the mouth before they eventually fall out, and are replaced by new teeth that grow in the back.

Despite having herbivorous diets similar to ruminants such as cattle, which release large quantities of digestive methane through exhaling and eructation burping , kangaroos release virtually none.

The hydrogen byproduct of fermentation is instead converted into acetate , which is then used to provide further energy.

Scientists are interested in the possibility of transferring the bacteria responsible for this process from kangaroos to cattle, since the greenhouse gas effect of methane is 23 times greater than carbon dioxide per molecule.

Groups of kangaroos are called mobs , courts or troupes , which usually have 10 or more kangaroos in them. Living in mobs can provide protection for some of the weaker members of the group.

This behavior enforces social cohesion without consequent aggression. During mutual sniffing, if one kangaroo is smaller, it will hold its body closer to the ground and its head will quiver, which serves as a possible form of submission.

Most other non-antagonistic behavior occurs between mothers and their young. Mother and young reinforce their bond though grooming. A mother will groom her young while it is suckling or after it is finished suckling.

Sexual activity of kangaroos consists of consort pairs. He sniffs her urine to see if she is in oestrus, a process exhibiting the flehmen response.

The male will then proceed to approach her slowly to avoid alarming her. Consort pairing may take several days and the copulation is also long.

Thus, a consort pair is likely to attract the attention of a rival male. Fighting has been described in all species of kangaroos.

Fights between kangaroos can be brief or long and ritualised. Smaller males fight more often near females in oestrus, while the large males in consorts do not seem to get involved.

Ritualised fights can arise suddenly when males are grazing together. However, most fights are preceded by two males scratching and grooming each other.

Sometimes, the challenge will be declined. Large males often reject challenges by smaller males. During fighting, the combatants adopt a high standing posture and paw at each other's heads, shoulders and chests.

They will also lock forearms and wrestle and push each other as well as balance on their tails to kick each other in the abdomen.

Brief fights are similar, except there is no forearm locking. The losing combatant seems to use kicking more often, perhaps to parry the thrusts of the eventual winner.

A winner is decided when a kangaroo breaks off the fight and retreats. Winners are able to push their opponents backwards or down to the ground.

They also seem to grasp their opponents when they break contact and push them away. These fights may serve to establish dominance hierarchies among males, as winners of fights have been seen to displace their opponent from resting sites later in the day.

Kangaroos have a few natural predators. The thylacine , considered by palaeontologists to have once been a major natural predator of the kangaroo, is now extinct.

Other extinct predators included the marsupial lion , Megalania and Wonambi. However, with the arrival of humans in Australia at least 50, years ago and the introduction of the dingo about 5, years ago, kangaroos have had to adapt.

Wedge-tailed eagles and other raptors usually eat kangaroo carrion. Goannas and other carnivorous reptiles also pose a danger to smaller kangaroo species when other food sources are lacking.

Along with dingoes, introduced species such as foxes, feral cats , and both domestic and feral dogs, pose a threat to kangaroo populations.

Kangaroos and wallabies are adept swimmers , and often flee into waterways if presented with the option.

If pursued into the water, a large kangaroo may use its forepaws to hold the predator underwater so as to drown it. Kangaroos have developed a number of adaptations to a dry, infertile country and highly variable climate.

As with all marsupials , the young are born at a very early stage of development—after a gestation of 31—36 days.

At this stage, only the forelimbs are somewhat developed, to allow the newborn to climb to the pouch and attach to a teat. In comparison, a human embryo at a similar stage of development would be about seven weeks old, and premature babies born at less than 23 weeks are usually not mature enough to survive.

When the joey is born, it is about the size of a lima bean. The joey will usually stay in the pouch for about nine months — days for the Western Grey before starting to leave the pouch for small periods of time.

It is usually fed by its mother until reaching 18 months. The female kangaroo is usually pregnant in permanence, except on the day she gives birth; however, she has the ability to freeze the development of an embryo until the previous joey is able to leave the pouch.

This is known as embryonic diapause , and will occur in times of drought and in areas with poor food sources. The composition of the milk produced by the mother varies according to the needs of the joey.

In addition, the mother is able to produce two different kinds of milk simultaneously for the newborn and the older joey still in the pouch.

Unusually, during a dry period, males will not produce sperm, and females will conceive only if enough rain has fallen to produce a large quantity of green vegetation.

Kangaroos and wallabies have large, elastic tendons in their hind legs. They store elastic strain energy in the tendons of their large hind legs, providing most of the energy required for each hop by the spring action of the tendons rather than by any muscular effort.

There is also a link between the hopping action and breathing: as the feet leave the ground, air is expelled from the lungs; bringing the feet forward ready for landing refills the lungs, providing further energy efficiency.

Studies of kangaroos and wallabies have demonstrated, beyond the minimum energy expenditure required to hop at all, increased speed requires very little extra effort much less than the same speed increase in, say, a horse, dog or human , and the extra energy is required to carry extra weight.

For kangaroos, the key benefit of hopping is not speed to escape predators—the top speed of a kangaroo is no higher than that of a similarly sized quadruped, and the Australian native predators are in any case less fearsome than those of other countries—but economy: in an infertile country with highly variable weather patterns, the ability of a kangaroo to travel long distances at moderately high speed in search of food sources is crucial to survival.

New research has revealed that a kangaroo's tail acts as a third leg rather than just a balancing strut.

Kangaroos have a unique three-stage walk where they plant their front legs and tail first, then push off their tail, followed lastly by the back legs.

The propulsive force of the tail is equal to that of both the front and hind legs combined and performs as much work as what a human leg walking can at the same speed.

A DNA sequencing project of the genome of a member of the kangaroo family, the tammar wallaby , was started in The dairy industry could also benefit from this project.

Eye disease is rare but not new among kangaroos. The first official report of kangaroo blindness took place in , in central New South Wales.

The following year, reports of blind kangaroos appeared in Victoria and South Australia. By , the disease had spread "across the desert to Western Australia".

Researchers at the Australian Animal Health Laboratories in Geelong detected a virus called the Wallal virus in two species of midges , believed to have been the carriers.

Kangaroo reproduction is similar to that of opossums. The egg still contained in the shell membrane, a few micrometres thick, and with only a small quantity of yolk within it descends from the ovary into the uterus.

There it is fertilised and quickly develops into a neonate. Even in the largest kangaroo species the red kangaroo , the neonate emerges after only 33 days.

Usually, only one young is born at a time. It is blind, hairless, and only a few centimetres long; its hindlegs are mere stumps; it instead uses its more developed forelegs to climb its way through the thick fur on its mother's abdomen into the pouch, which takes about three to five minutes.

Once in the pouch, it fastens onto one of the four teats and starts to feed. Almost immediately, the mother's sexual cycle starts again.

Another egg descends into the uterus and she becomes sexually receptive. Then, if she mates and a second egg is fertilised, its development is temporarily halted.

Meanwhile, the neonate in the pouch grows rapidly. After about days, the baby joey is sufficiently large and developed to make its full emergence out of the pouch, after sticking its head out for a few weeks until it eventually feels safe enough to fully emerge.

From then on, it spends increasing time in the outside world and eventually, after about days, it leaves the pouch for the last time.

The kangaroo has always been a very important animal for Aboriginal Australians , for its meat , hide, bone, and tendon.

Kangaroo hides were also sometimes used for recreation; in particular there are accounts of some tribes Kurnai using stuffed kangaroo scrotum as a ball for the traditional football game of marngrook.

In addition, there were important Dreaming stories and ceremonies involving the kangaroo. Aherrenge is a current kangaroo dreaming site in the Northern Territory.

Unlike many of the smaller macropods, kangaroos have fared well since European settlement. European settlers cut down forests to create vast grasslands for sheep and cattle grazing, added stock watering points in arid areas, and have substantially reduced the number of dingoes.

Kangaroos are shy and retiring by nature, and in normal circumstances present no threat to humans.

In , Lulu, an eastern grey which had been hand-reared, saved a farmer's life by alerting family members to his location when he was injured by a falling tree branch.

There are very few records of kangaroos attacking humans without provocation; however, several such unprovoked attacks in spurred fears of a rabies -like disease possibly affecting the marsupials.

The only reliably documented case of a fatality from a kangaroo attack occurred in New South Wales in A hunter was killed when he tried to rescue his two dogs from a heated fray.

Other suggested causes for erratic and dangerous kangaroo behaviour include extreme thirst and hunger. In July , a male red kangaroo attacked a year-old woman in her own backyard as well as her son and two police officers responding to the situation.

The kangaroo was capsicum sprayed pepper sprayed and later put down after the attack. A collision with a vehicle is capable of killing a kangaroo.

Kangaroos dazzled by headlights or startled by engine noise often leap in front of cars. Small vehicles may be destroyed, while larger vehicles may suffer engine damage.

The risk of harm or death to vehicle occupants is greatly increased if the windscreen is the point of impact. As a result, "kangaroo crossing" signs are commonplace in Australia.

Vehicles that frequent isolated roads, where roadside assistance may be scarce, are often fitted with " roo bars " to minimise damage caused by collision.

Bonnet -mounted devices, designed to scare wildlife off the road with ultrasound and other methods, have been devised and marketed.

If a female is the victim of a collision, animal welfare groups ask that her pouch be checked for any surviving joey, in which case it may be removed to a wildlife sanctuary or veterinary surgeon for rehabilitation.

Council road signs often list phone numbers for callers to report injured animals. The kangaroo is a recognisable symbol of Australia.

The kangaroo and emu feature on the Australian coat of arms. Kangaroos have also been featured on coins, most notably the five kangaroos on the Australian one dollar coin.

The Australian Made logo consists of a golden kangaroo in a green triangle to show that a product is grown or made in Australia. Walla Walla Brand leather and skins ; Arnold V.

Even today, Australia's national airline, Qantas , uses a bounding kangaroo for its logo. The kangaroo and wallaby feature predominantly in Australian sports teams names and mascots.

Examples include the Australian national rugby league team the Kangaroos and the Australian national rugby union team the Wallabies.

In a nation-wide competition held in for the XII Commonwealth Games by the Games Australia Foundation Limited in , Hugh Edwards' design was chosen; a simplified form of six thick stripes arranged in pairs extending from along the edges of a triangular centre represent both the kangaroo in full flight, and a stylised "A" for Australia.

Kangaroos are well represented in films, television, books, toys and souvenirs around the world. Skippy the Bush Kangaroo was a popular s Australian children's television series about a fictional pet kangaroo.

Historically, the kangaroo has been a source of food for indigenous Australians. Kangaroo meat has a high concentration of conjugated linoleic acid CLA compared with other foods, and is a rich source of vitamins and minerals.

Most kangaroo meat is currently sourced from wild animals as a byproduct of population control programs. From Wikipedia, the free encyclopedia.

The 'usual' situation for parasitic helminths of grey kangaroos is that pairs of parasite species occur in the two host species.

The exact timing of reactivation during oogenesis in kangaroos is still not known. Vectors for kangaroo trypanosomes are likely to be tabanid flies, although this has yet to be definitively established.

All seeds placed at trees had the flesh removed, so that seed removal could be attributed to rats rather than the frugivorous musky rat kangaroo.

Her dissertation investigated the effects of social and metabolic stress on food-hoarding decisions in kangaroo rats. We can describe the latter by saying that we perceive the kangaroo as grey.

Anomalies like the platypus and the kangaroo challenged natural science's ability to as it were carve nature at the joints.

This was due to the fragility of the milk carton traps; they were trampled by sheep and kangaroos, and could be eaten completely in less than four weeks.

Grey kangaroos represent an ideal host species-pair in which to investigate whether speciation in the host always results in the formation of species-pairs of parasites.

Similarly, we can perceive an object such as a kangaroo or we can perceive a state of affairs that the kangaroo has the property of being grey.
