Kangaroo
Kangaroos are marsupials from the family Macropodidae (macropods, meaning "large foot"). In common use, the term is used to describe the largest species from this family, the red kangaroo, as well as the antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo. Kangaroos are indigenous to Australia and New Guinea. The Australian government estimates that 42.8 million kangaroos lived within the commercial harvest areas of Australia in 2019, down from 53.2 million in 2013. As with the terms " wallaroo" and "wallaby", "kangaroo" refers to a paraphyletic grouping of species. All three terms 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. There are also the tree-kangaroos, another type of macropod which inhabit the upper branches ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Osphranter Rufus
The red kangaroo (''Osphranter rufus'') is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial. It is found across mainland Australia, except for the more fertile areas, such as southern Western Australia, the eastern and southeastern coasts, and the rainforests along the northern coast. Taxonomy The initial description of the species by A.G. Desmarest was published in 1822. The type location was given as an unknown location west of the Blue Mountains. The author assigned the new species to the genus ''Kangurus''. In 1842, Gould reassigned the species to the genus ''Osphranter'', a taxon later submerged as a subgenus of '' Macropus''. A taxonomic restructure in 2015 in ''Taxonomy of Australian Mammals'' by Jackson and Groves promoted ''Osphranter'' back to the genus level, redefining the red kangaroo, among others, as a species within the genus ''Osphranter''. This was further supported by genetic analysis in 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Grey Kangaroo
The western grey kangaroo (''Macropus fuliginosus''), also referred to as a western grey giant kangaroo, black-faced kangaroo, mallee kangaroo, sooty kangaroo and (when referring to the Kangaroo Island subspecies) Kangaroo Island grey kangaroo, is a large and very common kangaroo found across almost the entire southern part of Australia, from just south of Shark Bay through coastal Western Australia and South Australia, into western Victoria (Australia), Victoria, and in the entire Murray–Darling basin in New South Wales and Queensland. Taxonomy Long known to the Aboriginal Australians, for Europeans, the western grey kangaroo was the centre of a great deal of sometimes comical taxonomic confusion for almost 200 years. It was first noted by European maritime exploration of Australia, European explorers when Matthew Flinders landed on Kangaroo Island in 1802. Flinders shot several for food, but assumed that they were eastern grey kangaroos. In 1803, Baudin expedition to Australia ...

Tree-kangaroo
Tree-kangaroos are marsupials of the genus ''Dendrolagus'', adapted for arboreal locomotion. They inhabit the tropical rainforests of New Guinea and far northeastern Queensland, Australia along with some of the islands in the region. All tree-kangaroos are considered threatened due to hunting and habitat destruction. They are the only true arboreal macropods. Evolutionary history The evolutionary history of tree-kangaroos possibly begins with a rainforest floor-dwelling pademelon-like ancestor. This ancestor possibly evolved from an arboreal possum-like ancestor as is suspected of all macropodid marsupials in Australia and New Guinea. During the late Eocene, the Australian/New Guinean continent began a period of drying that caused a retreat in the area of rainforest, which forced the ancestral pademelons to begin living in a drier, rockier environment. After some generations of adaptation to the new environment, the pademelons may have evolved into rock-wallabies (''Petr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Grey Kangaroo
The eastern grey kangaroo (''Macropus giganteus'': gigantic large-foot; also great grey kangaroo or forester kangaroo) is a marsupial found in the eastern third of Australia, with a population of several million. Although a large ''M. giganteus'' kangaroo male can typically weigh up to and have a length of well over , the scientific name is misleading as the red kangaroo of the semi-arid inland is larger, weighing up to . Taxonomy The eastern grey kangaroo was described by George Shaw (biologist), George Shaw in 1790 as ''Macropus giganteus''. Subspecies While two subspecies were recognised by Mammal Species of the World (MSW), there is some dispute as to the validity of this division, and the subspecies are not recognised by the Australian Mammal Society, the IUCN, or the American Society of Mammalogists, which produces the successor of the MSW. Albert Sherbourne Le Souef created the Tasmanian subspecies in 1923, based on coat colour. In 1972 John Augustus Walter Kirsch, Kirs ...

Joey (marsupial)
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including Kangaroo, kangaroos, Koala, koalas, Opossum, opossums, Phalangeriformes, possums, Tasmanian devil, Tasmanian devils, Wombat, wombats, Wallaby, wallabies, and Bandicoot, bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to Placentalia, placentals. The evolutionary split between placentals and marsupials occurred 125-160 million years ago, in the Middle Jurassic-Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pouch (marsupial)
The pouch is a distinguishing feature of female marsupials and monotremes, and rarely in males as well, such as in the yapokNogueira, José Carlos, et al.Morphology of the male genital system of Chironectes minimus and comparison to other didelphid marsupials. Journal of mammalogy 85.5 (2004): 834-841. and the extinct thylacine. The name marsupial is derived from the Latin ''marsupium'', meaning "pouch". This is due to the occurrence of epipubic bones, a pair of bones projecting forward from the pelvis. Marsupials give birth to a live but relatively undeveloped foetus called a joey. When the joey is born it crawls from inside the mother to the pouch. The pouch is a fold of skin with a single opening that covers the teats. Inside the pouch, the blind offspring attaches itself to one of the mother's teats and remains attached for as long as it takes to grow and develop to a juvenile stage. Variations Pouches are different amongst different marsupials, two kinds distinguish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lumholtz's Tree-kangaroo
Lumholtz's tree-kangaroo (''Dendrolagus lumholtzi'') is a rare, long-tailed marsupial found in rainforests in northeastern Australia. Like most tree-kangaroos (genus ''Dendrolagus''), it lives alone in trees and feeds on plant matter. It belongs to the macropod family ( Macropodidae) with kangaroos, and carries its young in a pouch like other marsupials. It is threatened by climate change and diseases, and is found in the hilly, fertile Atherton Tableland near Cairns in north east Queensland. Name The species name ''lumholtzi'' is after the Norwegian explorer Carl Sofus Lumholtz (1851–1922), who was the first European to record a specimen in 1883. The local indigenous Dyirbal and Yidiny language name may have been either "mabi" or "mapi". Description and habitat It is the smallest of all tree-kangaroos, with males weighing an average of 7.2 kg (16 lbs) and females 5.9 kg (13 lbs). Its head and body length ranges , and its tail, . It has powerful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macropus
''Macropus'', from the Ancient Greek words μάκρος (''mákros''), meaning "long", and πους (''pous''), meaning "foot", is a marsupial genus in the family Macropodidae. It has two extant species of large terrestrial kangaroos. Thirteen known extinct species are recognised. The type species is the eastern grey kangaroo. Taxonomy In 2019, a reassessment of macropod taxonomy determined that ''Osphranter'' and ''Notamacropus'', formerly considered subgenera, should be moved to the genus level. This change was accepted by the Australian Faunal Directory in 2020. Extant Species Fossils A currently-unnamed Pleistocene ''Macropus'' species from Australia Australia, officially the Commonwealth of Australia, is a country comprising mainland Australia, the mainland of the Australia (continent), Australian continent, the island of Tasmania and list of islands of Australia, numerous smaller isl ... was the largest kangaroo ever, with an estimated mass of around 274 kg ( ...

Antilopine Kangaroo
The antilopine kangaroo (''Osphranter antilopinus''), also known as the antilopine wallaroo or the antilopine wallaby, is a species of Macropodidae, macropod found in northern Australia: in Cape York Peninsula in Queensland, the Top End of the Northern Territory, and the Kimberley (Western Australia), Kimberley region of Western Australia. It is a locally common, gregarious grazer. Taxonomy The description of the species by John Gould was published in 1842, one of four new species of 'kangaroos' presented before the Zoological Society of London in 1841. The type location was given as Port Essington. The author assigned the new species to the genus ''Osphranter'', a taxon later submerged as a subgenus of ''Macropus'', and recognised an affinity with his earlier description of ''Macropus robustus'' (known as the common wallaroo or euro). A taxonomic restructuring in 2019, based on genetic analysis, promoted ''Osphranter'' back to genus level, redefining the antilopine kangaroo an ...
