Potoroos are small kangaroos also called "rat-kangaroos." Males are most often heavier than females. About the size of a rabbit (700 mm, of which 300 mm is the tail), Potorous longipes can be distinguished from other potoroos by its long back feet and toes. Members of the species also have strong front feet and claws. The fur is dense, with a soft grey-brown color that is paler on the stomach and feet.
Range mass: 1 to 2 kg.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger
Average lifespan
Status: captivity: 15.3 years.
Mostly found in a range of predominantly "wetter" forest types, from wet sclerophyll forests at an altitude of 800m to lowland sclerophyll forests and warm temperate rainforest at 150m. Limited to areas with high soil moisture content throughout the year (because of ecology of food items) and areas with densely vegetated locations for shelter. Most Long-footed Potoroos are found in sites with an average annual rainfall of 1100 to 1200mm (43 to 47in).
Terrestrial Biomes: forest
Perception Channels: tactile ; chemical
Only found in the forests of south-eastern Australia. Specifically, forests of East Gippsland, north-eastern Victoria south of Mount Buffalo, and south-eastern New South Wales.
Biogeographic Regions: australian (Native )
Obligate fungivore, feeding on the fruiting bodies of more than 30 species of underground fungi, which grow in association with tree roots. Occasionally insects, seeds, and other plant materials become a part of the diet, which is 80% fungi. Feeding locations are easily identified by small, cone-shaped holes, dug in search of fungi.
Populations are threatened by habitat loss or fragmentation caused by logging and road construction associated with logging. Wildfire and fuel-reduction burning practices also threaten populations. Introduced predators, including the Red Fox, Dingo, and feral Dog, are important causes of mortality of the Long-footed Potoroo. Conservation efforts are being made by the Department of Natural Resources and Environment in Australia. These efforts include careful management in National Parks (2 known populations in Snowy River National Park), establishment of special management areas, predator control in management areas, long-term monitoring of populations, and public education about the Long-footed Potoroo.
IUCN Red List of Threatened Species: endangered
Most young are born in the winter, spring, and early summer, but the Long-footed Potoroo likely breeds throughout the year. There can be several litters per year (1 young per litter), with the average being 2.5 to 3 young per year. Young remain in the pouch for 140 to 150 days.
Key Reproductive Features: gonochoric/gonochoristic/dioecious (sexes separate); sexual
Average gestation period: 38 days.
Average number of offspring: 1.
Average age at sexual or reproductive maturity (female)
Sex: female: 755 days.

Klokánek dlouhoprstý (Potorous longipes) je drobný vačnatec, žijící v lesích jihovýchodní Austrálie. Spíše než klokana připomíná krysu. Dospělý klokánek váží 2 - 4 kg a od ostatních klokánků se liší prodlouženými chodidly na zadních končetinách. Srst na těle je šedohnědá, břicho je světlejší, pánevní končetiny naopak černé.
Klokánek dlouhoprstý je samotářský, aktivní v noci. Ve dne se ukrývá ve vegetaci, po setmění shání potravu, kterou vyhrabává kratšíma, ale silnýma předníma nohama. Pohybuje se po čtyřech, při rychlém pohybu poskakuje po zadních. Živí se převážně houbami, plodnice hub tvoří přibližně čtyři pětiny jeho potravy, celkově se živí asi 30 různými druhy, mimoto pojídá ještě hmyz a zelené části rostlin.
Březost trvá 38 dní, rodí jedno mláďě, které pak ve vaku saje mléko po dobu až pěti měsíců a s matkou zůstává ještě další dva až tři měsíce.

Das Langfußpotoroo (Potorous longipes), auch als Langfuß-Kaninchenkänguru bezeichnet, ist ein Beutelsäuger aus der Familie der Rattenkängurus (Potoroidae), das in vier voneinander getrennten Populationen im südöstlichen Australien vorkommt. Es lebt im östlichen Gippsland und in den Barry Mountains im nordöstlichen Victoria und im South-East-Forest-Nationalpark und im Yambulla State Forest im südöstlichen New South Wales.[1]
Das Langfußpotoroo ist ein relativ großes Kaninchenkänguru und erreicht eine Kopfrumpflänge von 38 bis 41,5 cm, hat einen 31,5 bis 32,5 cm langen Schwanz und wiegt 1,6 bis 2,2 kg. Auf der Rückenseite sind die Tiere graubraun gefärbt, auf der Bauchseite hellgrau. Wangen, Vorderpfoten und Füße sind grau. Die Ohren sind klein und abgerundet und auf ihrer Hinterseite dicht behaart. Der Schwanz ist relativ dick und nur spärlich behaart. Die Schwanzunterseite ist heller als die Oberseite.[1]
Das Langfußpotoroo lebt in gemäßigten, immergrünen Feuchtwäldern und in Galeriewäldern mit dichtem Unterholz in Höhen von 100 bis 1100 Metern über dem Meeresspiegel. Die Bodenfeuchtigkeit im Lebensraum ist das ganze Jahr über sehr hoch. Die Tiere sind einzelgängerisch und dämmerungsaktiv. Den Tag verbringen Langfußpotoroos allein oder paarweise in Verstecken in Büschen oder unter Baumstämmen. Die Territorien der Männchen sind 16 bis 65 ha groß, die der Weibchen sind mit 14 bis 43 ha deutlich kleiner. Die Hauptaktivitätszeit ist die Zeit um den Sonnenuntergang und vor dem Sonnenaufgang. Die Art ernährt sich vor allem von unterirdisch wachsenden, trüffelartigen Pilzen, die mit den Vorderpfoten ausgegraben werden. Pilze machen 80 bis über 90 % ihrer Nahrung aus. Außerdem werden Samen, Früchte, Blätter, Pflanzenstängel und Wirbellose gefressen. Über die Fortpflanzung ist nur wenig bekannt. Nach der Geburt bleibt das Jungtier für etwa 5 Monate im Beutel und nach der Entwöhnung bleibt es noch bis zum Alter von einem Jahr im Territorium der Mutter. Weibchen und Männchen werden mit einem Alter von 2 Jahren geschlechtsreif. Ein Weibchen kann zwei bis drei Jungtiere im Jahr bekommen.[1]
Das Langfußpotoroo wird von der IUCN als gefährdet (Vulnerable) eingestuft. Es hat nur einen kleinen, stark fragmentierten Lebensraum, der jedoch größtenteils verschiedene Schutzgebiete umfasst. Der Gesamtbestand der Art wird auf einige hundert bis wenige tausend Tiere geschätzt. Ein Versuch den Bestand des Langfußpotoroo durch Nachzuchten zu vergrößern war nicht erfolgreich. Hauptbedrohung der Art sind Rotfüchse und verwilderte Hunde.[1][2]

Es lebt im östlichen Gippsland und in den Barry Mountains im nordöstlichen Victoria und im South-East-Forest-Nationalpark und im Yambulla State Forest im südöstlichen New South Wales.
The long-footed potoroo (Potorous longipes) is a small marsupial found in southeastern Australia, restricted to an area around the coastal border between New South Wales and Victoria. It was first recorded in 1967 when an adult male was caught in a dog trap in the forest southwest of Bonang, Victoria.[3] It is classified as vulnerable.[1]
P. longipes is the largest species of Potorous, resembling the long-nosed potoroo, Potorous tridactylus. It is a solitary, nocturnal creature, feeding on fungi, vegetation, and small invertebrates. It differs from P. tridactylus in its larger feet and longer tail.[4]
Current threats to the species include predation by introduced feral cats and foxes, and loss of habitat from logging within its limited range.
The scientific name of the animal commonly known as the long-footed potoroo is Potorous longipes. Potoroo is the common name for all of the three other species in the genus Potorous, Gilbert's potoroo, P. gilbertii, the broad-faced potoroo, P. platyops, and long-nosed potoroo, P. tridactylus.[5] P. longipes is the largest potoroo, and most resembles P. tridactylus. The species was first recorded in 1967 in the East Gippsland region of Victoria, Australia.[6] The formal description was published in 1980.[2] Remains of the long-footed potoroo were found in predator droppings in 1986.[7]
The long-footed potoroo is a very rare marsupial only found in Australia. A potoroo is a small type of kangaroo-like marsupial.[5] It is about the size of a rabbit and its common name suggests, it has very long hind feet. These feet have long toes with very strong claws.[8] The species is the largest potoroos with males weighing up to 2.3 kg (5.1 lb) and females 1.4 kg (3.1 lb). The entire body length is 380–415 mm (15.0–16.3 in). The tail can be between 315 and 325 mm (12.4 and 12.8 in) in length, while the hind foot is 103–114 mm (4.1–4.5 in). This animal can be differentiated from other potoroos by its long back feet,[5] which are the same length relative to its head. It has an extra footpad called the hallcual pad.[6] The long-footed potoroo hops in a similar fashion to a kangaroo, yet can use its tail to grasp objects.[9] It has a soft, dense coat, with grayish-brown fur that slowly fades into a lighter color on the feet and belly.[8]
The long-footed potoroo lives in a range of montane forests. It has also been found in the warmer temperate rainforest. This species lives where the soil is constantly moist.[7] It spends its day time sleeping in a nest on the ground in a hidden, sheltered area.[8] An essential feature of the long-footed potoroo's habitat is the dense vegetation cover that supplies protection and shelter from predators. This species was not known to science until 1967, so historically, it is inadequately understood. It has a very restricted area where it lives. The main populations can be found in Victoria, in the Barry Mountains, which is in the northeast part of the state, and in the East Gippsland, located in the far east. A smaller population lives north of the Victorian border in the south-east forest of New South Wales.[1]
The long-footed potoroo is very difficult to find in the wild due to its shy behavior. The National Recovery Plan states that a few thousand individuals are unlikely to remain in the wild as of now; only a few hundred long-footed potoroosmay survive.[1]
Long-footed potoroos' diet normally consists of up to 91% of fruiting fungi found under ground.[1] They are known to consume up to 58 different species of fungi as part of their diet.[10] These underground fungi are also called sporocarps or truffles. If necessary, they may also eat fruits, plant material, and soil-dwelling invertebrates. Their jaws have shearing premolars and molars that are rounded at the top, indicating a varied diet is consumed.[9]
The long-footed potoroo plays a part in the symbiotic relationship between the fungi (Ectomycorrhizae) and the trees. It helps this relationship by releasing the spores of the fruiting fungi through its fecal material. In turn, this helps keep the forest healthy, benefiting both the fungi and the forest.[8] The species of fungi that are eaten in the winter and summer are similar, but the amount of each type of fungal species varies between seasons and years.[7] It has a sacculated fore stomach in which bacterial fermentation occurs. This aids in the breakdown of fungal cell walls.[9]
The long-footed potoroo is very shy and elusive. It can produce a vocalization, a low kiss kiss sound when stressed or to communicate to its offspring.[8] Although the long-footed potoroo is a nocturnal species, it may partake in early-morning basking in the sun.[11] The long-footed potoroo is constantly hidden from plain sight. Under normal conditions, males are not aggressive. Nevertheless, if provoked, they can become aggressive in defending their home.[11]
Breeding can occur all year, yet most young are born in the winter, spring, and early summer. Higher rainfall and deep, moist soil full of leaf litter provides a stable food supply. In turn, these periods of good conditions allows breeding to occur easily.[7] When a female is in estrus, nearby males fight with one another, until dominance is established.[11] The species has a monogamous mating system.[12] The gestation period is around 38 days. In captivity, the offspring stay in the mother's pouch for 140 to 150 days. The offspring then reaches sexual maturity around 2 years old.[8] Females can give birth up to three young per year, though one or two young is most commonly seen.[5] After the young leave the pouch, they can stay with their mothers up to 20 weeks until they become independent. They stay in the mother's territory up to 12 months before leaving.[7] The long-footed potoroo exhibits postpartum oestrus and embryonic diapauses.[11]
The long-footed potoroo moves to different parts of its territory due to the distribution of fungi. Thus seasonally, their territory boundaries change following the distribution of truffles. Males use a larger home range area than females use. The species is territorial and the territories of mated pairs can overlap with each other, but not with other pairs. The home range of the long-footed potoroo is between 22 and 60 ha in East Gippsland and between 14 and 23 ha in north-eastern Victoria.[7]
As of 2006, the long-footed potoroo has been classified as endangered (EN) by the IUCN Red List. According to the IUCN Red List, the long-footed potoroo is considered endangered because its area of occurrence is less than 5,000 km2. The dispersed area where the animal is found is most likely in a decline of the number of individuals due to predators and competition for food from introduced pigs.[1] It is listed as an endangered species on schedule 1 of the New South Wales Threatened Species Conservation Act 1995. It is also considered an endangered species under the Commonwealth Environmental Protection and Biodiversity Conservation Act 1999, and as endangered by the Victorian Flora and Fauna Guarantee Act 1988.[8]
Their most serious predators include the red fox, feral cats, and wild dogs, all invasive species. Their habitat is greatly disturbed due to building roads, thus they have seemed to move along these roads and forage for food in these areas. This also causes a threat from being hit with a motor vehicle. In Victoria, the State Forest has about half of the long-footed potoroo population. Introduced pigs may be a large competitor for the long-footed potoroo's specialized diet.[1]
Information on this rare species is spotty. Thus, to conserve it effectively, further studies on its way of life and habitat need to be conducted. Research was performed on a small captive population that was able to breed in the 1980s and 1990s at the Healesville Sanctuary.[8] Small steps have been taken to increase the population of long-footed potoroo and to protect it from extinction. In the State Forest of Victoria, the long-footed potoroo is protected through special areas in which logging is monitored or prevented and burning of the forest has been reduced.[1] Their natural predators such as the wild dogs, red fox and feral cats have also been put under control. This will allow the long-footed potoroo to reclaim their habitat and allow their numbers to rise again. Conservation plans such as these will not only benefit the long-footed potoroo, but will also be beneficial to other threatened animal species in this area.[8]
Over 82% of its habitat was burnt during the 2019-2020 Australian bushfires.[13]

Potorous longipes, communément appelé Potoroo à longs pieds, est une espèce de marsupiaux de la famille des Potoroidae et vivant dans des régions très limitées du sud-est de l'Australie. Il a été découvert en 1967 quand un animal adulte a été pris accidentellement dans un piège dans le sud-ouest de la forêt de Bonang, au Victoria. Il est considéré comme en danger.
C'est le plus grand des potorous et il ressemble beaucoup à Potorous tridactylus (Potorooo au long nez) mais dont il se distingue par ses pattes plus longues et sa queue plus grosse. C'est un animal solitaire et nocturne se nourrissant de champignons et autres végétaux ainsi que de petits invertébrés.
L'espèce est menacée depuis l'importation de chats sauvages et de renards ainsi que par l'abattage des arbres de son habitat (comme l'abattage accidentel de 400 m2 dans le parc national Errinundra, dans l'est du Gippsland en septembre 2005.)
Potorous longipes est uniquement connue dans trois zones disjointes dans les Nouvelle-Galles du Sud et de Victoria en Australie.

Il potoroo dai piedi lunghi (Potorous longipes Seebeck e Johnson, 1980) è una specie di potoroo diffusa in Australia sud-orientale, in una piccola area costiera al confine tra il Nuovo Galles del Sud e il Victoria. Venne scoperto nel 1967, quando un maschio adulto rimase intrappolato in una trappola per cani nella foresta a sud-ovest di Bonang, nel Victoria[3]. È classificato tra le specie in pericolo[2].
Il potoroo dai piedi lunghi è il più grande tra i potoroo ed è molto simile a quello dal naso lungo (Potorous tridactylus). È una creatura solitaria e notturna che si nutre di funghi, vegetali e piccoli invertebrati. Si differenzia dal potoroo dal naso lungo per avere piedi più grandi e coda più lunga[4]. Il corpo è lungo tra 38 e 41 cm, la coda tra 31,5 e 32,5 cm e i piedi tra 10,5 e 11,5 cm. Il peso può variare tra 1600 e 2200 g. Il colore del corpo è marrone sul dorso e grigio chiaro sul lato ventrale. La coda è marrone inferiormente e lateralmente e nera sul lato superiore.
Tra le minacce che attualmente gravano su questa specie ricordiamo la predazione da parte dei gatti rinselvatichiti e delle volpi, introdotti dall'uomo, e tutti i rischi derivanti dal vivere in un areale limitato (ad esempio la frana accidentale di 400 metri quadrati nel Parco Nazionale di Errinundra, East Gippsland, nel settembre 2005)[5].
La Zoological Society of London, in base a criteri di unicità evolutiva e di esiguità della popolazione, considera Potorous longipes una delle 100 specie di mammiferi a maggiore rischio di estinzione.

De grootpootpotoroe (Potorous longipes) is een kangoeroerat uit het geslacht der potoroes (Potorous).
De bovenkant van het lichaam is bruin, de onderkant lichtgrijs. De vleeskleurige voeten zijn zeer groot. De nauwelijks behaarde staart is van boven zwart en van onderen en aan de zijkanten bruin. De kop-romplengte bedraagt 380 tot 410 mm, de staartlengte 315 tot 325 mm, de achtervoetlengte 103 tot 114 mm en het gewicht 1600 tot 2200 g.
Deze solitaire soort is 's nachts actief, leeft op de grond, bouwt een nest in dichte vegegatie en eet schimmels (vooral paddenstoelen), ongewervelden en plantaardig materiaal, dat hij allemaal uit de bodem opgraaft.
Deze soort komt voor in vochtige bossen in het oosten van Victoria (staat) en nabijgelegen delen van Nieuw-Zuid-Wales (Zuidoost-Australië). Het is een zeer schuwe en verborgen levende soort.
Per worp wordt er slechts één jong geboren, dat 5 maanden aan een tepel hangt in de buidel van de moeder. Daarna blijft het jong nog 2 tot 3 maanden bij haar. De draagtijd duurt 38 dagen. De geboorte kan plaatsvinden in alle seizoenen behalve de herfst.

Långfotad kängururåtta (Potorous longipes[2][3][4][5]) är en pungdjursart som beskrevs av Seebeck och Peter G. Johnston 1980. Potorous longipes ingår i släktet Potorous, och familjen råttkänguruer.[6][7] Inga underarter finns listade.[6]
Den långfotade kängururåttan blir 38 till 41,5 cm lång (huvud och bål) och har en 31,5 till 32,5 cm lång svans. Honor är med cirka 1,7 kg lättare än hannar som väger ungefär 2,3 kg. Som det svenska namnet antyder är bakfötterna med 10,3 till 11,4 cm längre än hos andra släktmedlemmar. Pälsen är spräcklig gråbrun på ovansidan och lite ljusare på undersidan.[8]
Pungdjuret förekommer i några från varandra skilda områden i sydöstra Australien (delstaterna New South Wales och Victoria). Arten vistas i kulliga områden och bergstrakter som är 100 till 1 100 meter höga. Habitatet utgörs av olika slags skogar.[1]
Individerna vilar på dagen i klotrunda bon som göms i växtligheten och de letar under natten efter föda. Arten äter främst svamparna underjordiska delar som kompletteras med olika växtdelar och ryggradslösa djur. En hanne och en hona delar ett revir som är 14 till 60 hektar stort.[8]
Honan kan i princip vara brunstig under alla årstider men ibland sker parningen endast under våren. Dräktigheten varar cirka 38 dagar och sedan föds en unge som lever 140 till 150 dagar i moderns pung (marsupium). Några honor kan vara dräktiga medan de har en unge i pungen och därför är antalet ungar per år upp till tre. Ungdjuren blir efter ungefär två år könsmogna. Några exemplar levde åtta år.[8]
Arten hotas av introducerade fiender som hundar, tamkatter, dingo och rödrävar och den fick med vildsvinet en konkurrent om samma föda. Flera exemplar dödas av bränder. Även människans byggaktiviteter påverkar beståndet.[8] IUCN kategoriserar arten globalt som sårbar (VU).[1]
I artens utbredningsområde förekommer några nationalparker. Jägare håller rödrävens bestånd på en låg nivå vad som stabiliserade pungdjurets population. Några exemplar hölls i fångenskap för att studera deras behov men dessa individer fortplantar sig inte lika lätt som vilda exemplar.[1]

後肢は頭部よりも長く、名前の由来になっている[4]。染色体数は2n=24[4]。乳頭の数は4個[4]。
1958年に野犬用の罠で発見されたが、1978年まで生体の捕獲例がなかった[4]。1986年にニューサウスウェールズ州で、1995年にビクトリア州北東部で発見された[5]。
標高100 - 1,200メートル以上にある硬葉樹林に生息する[5]。主に年間降雨量1,100 - 1,200ミリメートルの地域に生息する[3][6]。地表棲[4]。ギプスランドでは行動圏は22 - 60ヘクタール、ビクトリア州北東部では14 - 23ヘクタールの行動圏内で生活する[5]。夜行性[3][4][6]。昼間は下生えや倒木の中などで過ごす[5]。
食性は植物食傾向の強い雑食で、主に(食性の88 - 91 %)地中にある菌類を食べるが[1][3][4]、植物質や無脊椎動物も食べる[5]。
繁殖様式は胎生。妊娠期間は38日と考えられている[3]。周年繁殖し[6]、ギプスランドでは主に7 - 9月に出産することが多い[5]。1回に1頭の幼獣を[4]、年に2 - 3回に分けて産む[3][6]。幼獣は生後140 - 150日は母親の育児嚢で生活する[5][6]。生後140 - 150日に育児嚢に入らなくなり独立する[4][6]。生後26か月で性成熟する[5]。
分布は限定的で、大きくギプスランド東部・ニューサウスウェールズ州南東部・ビクトリア州北東部の3つの個体群に分かれる。森林伐採や道路建設による生息地の破壊により生息数が減少している[3][6]。生息地はスノーウィー・リバー国立公園などが含まれるものの大部分が州の所有林のため厳重に管理されているものの伐採することも可能で[1][3]、伐採が予定されている場所もある[4]。人為的に移入されたディンゴ・野犬・アカギツネによる捕食などによっても生息数は減少し[4][6]、野生化したブタによる食物の競合や堆積層の破壊なども懸念されている[1]。1988年にビクトリア州、1995年にニュー・サウス・ウェールズ州で法的に絶滅危惧種に掲載されている[5]。
긴발쥐캥거루(Potorous longipes)는 쥐캥거루과에 속하며, 오스트레일리아 남동부와 뉴사우스웨일스주와 빅토리아주 사이의 해안 경계선 주변의 작은 지역에서 발견되는 종이다. 1967년 발견된 종으로 빅토리아 주 보낭 남서부 숲에서 성체 수컷이 개 덫에 걸려 포획되었다.[3] 멸종위기종으로 분류하고 있다.[2] 긴발쥐캥거루는 가장 큰 쥐캥거루 종으로 긴코쥐캥거루(Potorous tridactylus)와 크게 닮았다. 홀로 생활하는 야행성 동물이며, 먹이는 버섯류와 풀 그리고 작은 무척추동물이다. 긴코쥐캥거루와 달리 발이 더 크고 꼬리는 길다.[4] 현재 도입된 야생 고양이와 여우 등의 포식자와 제한된 지역에서의 벌목 등에 의해 멸종 위협을 받고 있다.
