A wallaby (/ˈwɒləbi/) is a small or middle-sized macropod native to Australia and New Guinea, with introduced populations in New Zealand,[1] Hawaii, the United Kingdom and other countries. They belong to the same taxonomic family as kangaroos and sometimes the same genus, but the common name "kangaroo" specifically refers to 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.[2]
There are nine species (eight extant and one extinct) of the brush wallaby (genus Notamacropus). Their head and body length is 45 to 105 cm (18 to 41 in) and the tail is 33 to 75 cm (13 to 30 in) long. The 19 known species of rock-wallabies (genus Petrogale) live among rocks, usually near water; two species in this genus are endangered. The two living species of hare-wallabies (genus Lagorchestes; two other species in this genus are extinct) are small animals that have the movements and some of the habits of hares. The three species (two extant and one extinct) of nail-tail wallabies (genus Onychogalea) have one notable feature: a horny spur at the tip of the tail; its function is unknown. The seven species of pademelons or scrub wallabies (genus Thylogale) of New Guinea, the Bismarck Archipelago, and Tasmania are small and stocky, with short hind limbs and pointed noses. The swamp wallaby (genus Wallabia) is the only species in its genus. Another wallaby that is monotypic is the quokka or short-tailed scrub wallaby (genus Setonix); this species is restricted to two offshore islands of Western Australia which are free of introduced predators. The seven species of dorcopsises or forest wallabies (genera Dorcopsis (four species, with a fifth as yet undescribed) and Dorcopsulus (two species)) are all native to the island of New Guinea.
One of the brush wallaby species, the dwarf wallaby (Notamacropus dorcopsulus), also native to New Guinea, is the smallest known wallaby species and one of the smallest known macropods. Its length is about 46 cm (18 in) from the nose to the end of the tail, and it weighs about 1.6 kg (3.5 lb).[3]
Wallabies are hunted for meat and fur.
The name wallaby comes from Dharug walabi or waliba.[citation needed][4] Another early name for the wallaby, in use from at least 1802, was the brush-kangaroo.[5]
Young wallabies are referred to as "joeys", like many other marsupials. Adult male wallabies are referred to as "bucks", "boomers", or "jacks". Adult female wallabies are referred to as "does", "flyers", or "jills". A group of wallabies is called a "mob", "court", or "troupe". Scrub-dwelling and forest-dwelling wallabies are known as "pademelons" (genus Thylogale) and "dorcopsises" (genera Dorcopsis and Dorcopsulus), respectively.
Although members of most wallaby species are small, some can grow up to approximately two metres in length (from the head to the end of the tail). Their powerful hind legs are used not only for bounding at high speeds and jumping great heights, but also to administer vigorous kicks to fend off potential predators. The tammar wallaby (Notamacropus eugenii) has elastic storage in the ankle extensor tendons, without which the animal's metabolic rate might be 30–50% greater.[6] It has also been found that the design of spring-like tendon energy savings and economical muscle force generation is key for the two distal muscle–tendon units of the tammar wallaby (Macropus-Eugenii).[7] Wallabies also have a powerful tail that is used mostly for balance and support.

Wallabies are herbivores whose diet consists of a wide range of grasses, vegetables, leaves and other foliage. Due to recent urbanization, many wallabies feed in semi-rural and urban areas. Wallabies cover vast distances for food and water, which is often scarce in their environment. Mobs of wallabies often congregate around the same water hole during the dry season.

Wallabies face several threats. Dingoes, domestic and feral dogs, feral cats, and red foxes are among their predators. Humans also pose a significant threat to wallabies due to increased interaction (wallabies can defend themselves with hard kicks and biting). Many wallabies have been involved in vehicular accidents, as they often feed near roads and urban areas.

Wallabies are not a distinct genetic group. Nevertheless, they fall into several broad categories.[citation needed] Brush wallabies of the genus Notamacropus, like the agile wallaby (Notamacropus agilis) and the red-necked wallaby (Notamacropus rufogriseus), are most closely related to the kangaroos and wallaroos and, aside from their size, look very similar. These are the ones most frequently seen, particularly in the southern states.[citation needed]
Rock-wallabies (genus Petrogale), rather like the goats of the Northern Hemisphere, specialise in rugged terrain and have modified feet adapted to grip rock with skin friction rather than dig into soil with large claws. There are at least 19 species and the relationship between several of them is still poorly understood. Several species are endangered. Captive rock-wallaby breeding programs, like the one at Healesville Sanctuary, have had some success and a small number have recently been released into the wild.[citation needed]
The banded hare-wallaby (Lagostrophus fasciatus) is thought to be the last remaining member of the once numerous subfamily Sthenurinae, and although once common across southern Australia,[citation needed] it is restricted to two islands off the Western Australian coast which are free of introduced predators. It is not as closely related to the other hare-wallabies (genus Lagorchestes) as the hare-wallabies are to the other wallabies.[citation needed]
New Guinea, which was, until fairly recent geological times, part of mainland Australia,[8] has at least five species of wallabies.[citation needed]
Wallabies are widely distributed across Australia, particularly in more remote, heavily timbered, or rugged areas, less so on the great semi-arid plains that are better suited to the larger, leaner, and more fleet-footed kangaroos.[citation needed] They also can be found on the island of New Guinea.[9]
Wallabies of several species have been introduced to other parts of the world, and there are a number of successfully breeding introduced populations, including:

A wallaby () is a small or middle-sized macropod native to Australia and New Guinea, with introduced populations in New Zealand, Hawaii, the United Kingdom and other countries.

Kangaroos are marsupials from the subfamily Macropodinae (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 estimated 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 of trees in the tropical rainforests of New Guinea, far northeastern Queensland, and some of the islands in the region. A general idea of the relative size of these informal terms could be: wallabies: head and body length of 45–105 cm (18–41 in) and tail length of 33–75 cm (13–30 in); the dwarf wallaby (the smallest of all known macropod species) is 46 cm (18 in) long and weighs 1.6 kg (3.5 lb); wallaroos: the black wallaroo (the smaller of the two species) with a tail length of 60–70 cm (24–28 in) and weight of 19–22 kg (42–49 lb) for males and 13 kg (29 lb) for females; kangaroos: a large male can be 2 metres (6 feet 7 inches) tall and weigh 90 kg (200 lb). tree-kangaroos: ranging from Lumholtz's tree-kangaroo: body and head length of 48–65 cm (19–26 in), tail of 60–74 cm (24–29 in), weight of 7.2 kg (16 lb) for males and 5.9 kg (13 lb) for females; to the grizzled tree-kangaroo: length of 75–90 cm (29.5–35.5 in) and weight of 8–15 kg (18–33 lb); 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. 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. This process is known as polyphyodonty and, amongst other mammals, only occurs in elephants and manatees. 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, despite a common misconception to the contrary. The kangaroo, along with the koala, are symbols of Australia. A kangaroo appears on the Australian coat of arms and on some of its currency, and is used as a logo for some of Australia's most well-known organisations, such as Qantas, and as the roundel of the Royal Australian Air Force. The kangaroo is important to both Australian culture and the national image, and consequently there are numerous popular culture references. Wild kangaroos are shot for meat, leather hides, and to protect grazing land. Kangaroo meat has perceived health benefits for human consumption compared with traditional meats due to the low level of fat on kangaroos.
The swamp wallaby (Wallabia bicolor) is a small macropod marsupial of eastern Australia. This wallaby is also commonly known as the black wallaby, with other names including black-tailed wallaby, fern wallaby, black pademelon, stinker (in Queensland), and black stinker (in New South Wales) on account of its characteristic swampy odour. The swamp wallaby is the only living member of the genus Wallabia.
The black-flanked rock-wallaby (Petrogale lateralis), also known as the black-footed rock-wallaby or warru, is a species of wallaby, one of several rock-wallabies in the genus Petrogale. A shy, nocturnal herbivore, its two main subspecies are found in mostly isolated populations across western and southern Western Australia (WA), the Northern Territory and parts of South Australia (SA). With some subspecies showing a decline in populations in recent years, the whole species is classed as an endangered species under the Commonwealth EPBC Act.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
