Bushy-tailed opossums are medium-sized opossums with a body length of 160 to 205 mm. The coat varies in coloration with a light cinnamon color dorsally and a grayish to white and orange tinged underside. On the head there are two broad black stripes forming a mask starting at the nose, over the eyes, and terminating at the top of the head. Separating these stripes is a gray bar running from the nose to the ears. The ears are 22 to 25 mm in length, naked and a brown/black color. Sexes seem to be similar in appearance.
The tail of G. venusta is the feature used to distinguish this species from all other South American opossums. It is the only opossum with a tail that is fully furred on the top and sides, hence the common name, bushy-tailed opossum. The tail is longer than the body with a total length of 195 to 205 mm (Emmons and Feer 1990; Langguth and Da Silva 1989; Marshall 1978; Tarifa and Anderson 1997). The tail is similar in coloration to the body and most specimens have an obvious white tip on the tail, though the intensity of the white varies from a long swatch to just a few scattered hairs (Langguth and Da Silva 1989; Marshall 1978). Da Silva and Langguth (1989) noted that the underside of the tail has transverse lines that are slightly inflated, similar to a pad. The hallux is opposable as well, which suggests a primarily arboreal lifestyle (Marshall 1978).
Bushy-tailed opossums have weak canines and weakly developed premolars and molars, except for an enlarged P2 and P3. The dentition looks most like a species of Caluromys or Caluromysiops. The dental formula is similar to other didelphids: 5/4:1/1:3/3:4/4=50 (Marshall 1978). One reference stated that the weight of a sub-adult male was 104 grams (Nogueira et al 1999), though no other weight records were found.
Range length: 160 to 205 mm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike
No studies have been conducted on food habits, but bushy-tailed opossums are likely to be omnivorous because they lack specialized dentition and because closely related opossums are also omnivorous. Caluromys philander individuals eat primarily fruit, nectar, and insects.
Primary Diet: omnivore
Bushy-tailed opossums are rare and no ecosystem roles are known. They may help to pollinate the flowers and disperse the seeds of fruiting trees through eating fruit and nectar.
The geographic range of bushy-tailed opossums, Glironia venusta, is known from 9 specimens collected in South America; specifically in Bolivia, Ecuador, Peru, and eastern Brazil. The holotype was identified in 1912 by Oldfield Thomas, and the most recent specimen was captured in 1989.
Biogeographic Regions: neotropical (Native )
All nine Glironia venusta specimens were located in upper or lower Amazonian rainforests from 300 to 1000 meters in elevation. Their morphology suggests that G. venusta is arboreal (Emmons and Feer 1990; Langguth and Da Silva 1989; Marshall 1978; Tarifa and Anderson 1997). Two additional individuals were observed by Emmons at Parque Nacional Manu in southeast Peru and northwest Bolivia in the Valle de Marchariapo in a dry forested area. Since no specimens were ever recovered from those areas, this is not considered a confirmed record of occurrence (Emmons and Feer 1990; Tarifa and Anderson).
Range elevation: 300 to 1000 m.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: rainforest
No studies have been published about the lifespan of Glironia venusta. Closely related, Caluromys philander individuals have been known to live up to 5 years in captivity and 41 months in the wild.
This aspect of their life history has not been studied. It is likely that arboreal snakes and nocturnal raptors, such as owls take bushy-tailed opossums. They probably escape predation primarily through their nocturnality, cryptic coloration, and avoidance.
Anti-predator Adaptations: cryptic
This species has also been known by the names Glironia venusta and Glironia venusta. Glironia venusta literally means an elegant or charming dormouse.
Since individuals were collected several years apart and many kilometers apart, little is known about how Glironia venusta communicates. An examination of the skull shows that they have a non-specific auditory region and a long narrow rostrum (Marshall 1978). Like most mammals, they probably rely primarily on olfaction and hearing to navigate, find food, and avoid predation. These opossums have large eyes, indicating they may use vision extensively as well.
Perception Channels: visual ; tactile ; acoustic ; chemical
The IUCN Red list states that bushy-tailed opossums are considered vulnerable because they have a severely fragmented habitat with a continuous decline in the amount of habitat available. The last assessment was in 1996.
Glironia venusta is not listed on CITES.
US Federal List: no special status
CITES: no special status
IUCN Red List of Threatened Species: least concern
There are no negative impacts of bushy-tailed opossums on humans.
Since they are rarely seen or captured, no positive aspects are known.
No studies have reported observing more than one individual at a time, so no data is available on mating systems in this species. Little information is available on related species as well.
Bushy-tailed opossums are non-pouched marsupials, which may give some indication on their reproductive cycle. The only data collected and published was on a sub-adult specimen captured in Brazil. Noqueira et al. (1999) completed a study and comparison of different didelphid male reproductive organs. In their study, the G. venusta reproductive system most resembled one from the Caluromys genus by having two bulbo-urethral pairs instead of three, as in most other didelphids.
No information on reproduction is available for G. venusta. There is also very little information on reproduction in closely related Caluromys species. Caluromys philander breeds several times each year, depending on resource availability and local conditions. Gestation periods are short, 24 days or less, and lactation occurs for up to 120 days. Bushy-tailed opossums have four mammae, which limits their litter size.
Range number of offspring: 4 (high) .
Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
No data has been collected on parental investment in Glironia venusta. As in all marsupials, females have a short gestation and a longer lactation period.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female)

Die Buschschwanz-Beutelratte (Glironia venusta) ist eine Säugetierart aus der Familie der Beutelratten (Didelphidae).
Das dichte, wollige Fell dieser Tiere ist bräunlich gefärbt, zwei dunkelbraune oder schwarze Längsstreifen auf ihrem Gesicht sorgen für ein maskenähnliches Aussehen. Der Schwanz ist etwas länger als der Körper und bis auf die unbehaarte Spitze relativ buschig. Diese Tiere erreichen eine Kopf-Rumpf-Länge von 16 bis 20 Zentimetern und eine Schwanzlänge von 20 bis 23 Zentimetern.
Bislang wurden nur neun Exemplare dieser Art gefunden, alle in den Regenwäldern Brasiliens, Perus, Ecuadors oder Boliviens. Aufgrund des Körperbaus (opponierbarer Daumen und Greifschwanz) vermutet man, dass sie auf Bäumen lebt.
Über die Lebensweise der Buschschwanz-Beutelratte ist kaum etwas bekannt. Wie die meisten anderen Beutelratten dürfte sie ein nachtaktiver, einzelgängerischer Allesfresser sein.
Obwohl die Buschschwanz-Beutelratte sehr selten ist, listet sie die IUCN als nicht gefährdet („least concern“).
Über die systematische Zuordnung der Buschschwanzbeutelratte besteht Uneinigkeit. Meist wird sie in die Unterfamilie Caluromyinae als naher Verwandter der Wollbeutelratten eingeordnet. Andere Systematiken sprechen ihr hingegen den Rang einer eigenen Unterfamilie (Glironiinae) zu.

The bushy-tailed opossum (Glironia venusta) is an opossum from South America. It was first described by English zoologist Oldfield Thomas in 1912. It is a medium-sized opossum characterized by a large, oval, dark ears, fawn to cinnamon coat with a buff to gray underside, grayish limbs, and a furry tail. Little is known of the behavior of the bushy-tailed opossum; less than 25 specimens are known. It appears to be arboreal (tree-living), nocturnal (active mainly at night) and solitary. The diet probably comprises insects, eggs and plant material. This opossum has been captured from heavy, humid, tropical forests; it has been reported from Bolivia, Brazil, Colombia, Ecuador and Peru. The IUCN classifies it as least concern.
The bushy-tailed opossum is the sole member of Glironia, and is placed in the family Didelphidae. It was first described by English zoologist Oldfield Thomas in 1912. Earlier, Glironia was considered part of the subfamily Didelphinae. A 1955 revision of marsupial phylogeny grouped Caluromys, Caluromysiops, Dromiciops (monito del monte) and Glironia under a single subfamily, Microbiotheriinae, noting the dental similarities among these. A 1977 study argued that these similarities are the result of convergent evolution, and placed Caluromys, Caluromysiops and Glironia in a new subfamily, Caluromyinae.[6] In another similar revision, the bushy-tailed opossum was placed in its own subfamily, Glironiinae.[3]
The cladogram below, based on a 2016 study, shows the phylogenetic relationships of the bushy-tailed opossum.[7]

Bare-tailed woolly opossum (Caluromys philander)
Brown-eared woolly opossum (Caluromys lanatus)
Kalinowski's mouse opossum (Hyladelphys kalinowskii)
The generic name is a compound of the Latin glir ("dormouse") and Greek suffix -ia (pertains to "quality" or "condition"). The specific name, venusta, means "charming" in Latin.[6]
The bushy-tailed opossum is a medium-sized opossum characterized by a large, oval, dark ears, fawn to cinnamon coat with a buff to gray underside, grayish limbs, and, as its name suggests, a furry tail. The face is marked by two bold, dark stripes extending from either side of the nose through the eyes to the back of the ears. These stripes are separated by a thinner grayish white band, that runs from the midline of the nose to the nape of the neck. The texture of hairs ranges from soft to woolly; the hairs on the back measure 7 to 8 millimetres (0.28 to 0.31 in).[6][8] Five nipples can be seen on the abdomen; it lacks a marsupium.[5] The tail, 19.5 to 22.5 centimetres (7.7 to 8.9 in) long, becomes darker and less bushy towards the tip. Basically the same in color as the coat, the tip may be completely white or have diffuse white hairs.[6]
The head-and-body length is typically between 16 and 20.5 centimetres (6.3 and 8.1 in), the hindfeet measure 2.7 to 3.1 centimetres (1.1 to 1.2 in) and the ears are 2.2 to 2.5 centimetres (0.87 to 0.98 in) long.[6] It weighs nearly 140 grams (4.9 oz).[9] The dental formula is 5.1.3.44.1.3.4 – typical of all didelphids. Canines and molars are poorly developed. Differences from Marmosa species (mouse opossums) include smaller ears, longer and narrower rostrum, and greater erectness in canines. The monito del monte has a similar bushy tail.[6][10] A study of the male reproductive system noted that the bushy-tailed opossum has two pairs of bulbourethral glands, as in Caluromys and Gracilinanus, but unlike other didelphids that have three pairs. The urethral grooves of the glans penis end near the tips.[11]
Little is known of the behavior of the bushy-tailed opossum. Less than 25 specimens are known.[5] A study noted the morphological features of the opossum that could allow for powerful movements during locomotion, and deduced that it is arboreal (tree-living).[12] It appears to be solitary and nocturnal (active mainly at night).[1] An individual was observed running through and leaping over vines, in a manner typical of opossums, probably hunting for insects. Its diet may be similar to that of the mouse opossums – insects, eggs and plant material.[10]
The bushy-tailed opossum has been captured from heavy, humid, tropical forests, and has not been recorded outside forests. It occurs up to an altitude of 5 kilometres (16,000 ft) above the sea level.[1] The range has not been precisely determined; specimens have been collected from regions of Bolivia, Brazil,[9][13][14] Colombia,[15][16] Ecuador and Peru. The IUCN classifies the bushy-tailed opossum as least concern, given its wide distribution and presumably large population. The major threats to its survival are deforestation and human settlement.[1]

La zarigüeya de cola de pincel, ratas pincel o glironia gris (Glironia venusta) es una especie de marsupial nativa de la cuenca amazónica, la única integrante del género Glironia. Es un animal muy poco conocido del que se tienen pocas referencias.
Las regiones dorsales de cabeza y tronco están cubiertas de pelo denso de color marrón a canela. Las regiones ventrales son más claras, de blanco a gris ceniciento. La textura varía desde suave y sedoso a lanudo y apretado. Una banda oscura surca cada ojo, aparentando ser una máscara.
La cola es larga y prensil y está cubierta de pelo en toda la superficie, característica que diferencia a esta zarigüeya del resto. Además, la cola en la base es del color del dorso, presenta un mechón de pelo blanco o salpicado de pelos de este color y se va ennegreciendo gradualmente hacia la punta.[3][4][5][6][7]
La estructura del cráneo y las piezas dentarias son similares a las especies de los demás géneros de la subfamilia, si bien externamente son más parecidas a las especies del género Marmosa.
Los hábitos dietéticos de esta especie son desconocidos, pero pueden ser similares a las especies del género Marmosa, basada en insectos, frutos, semillas e incluso huevos.
No se dispone de datos relativos a la reproducción de la especie.
El aparato genital masculino es característico de la subfamilia Caluromyinae, presentando dos bulbos uretrales en lugar de tres como ocurre en Didelphinae. Las hembras no presentan marsupio.
Glironia venusta es eminentemente arborícola aunque desciende al suelo al menos para alimentarse, pues Marshall en 1978 consiguió un ejemplar en el sotobosque.[3]
Se han registrado por lo menos 28 hallazgos de ejemplares de esta especie: 5 en Perú 4 en Bolivia, 2 en Ecuador, 14 en Brasil y 3 en Colombia. Con cada vez más registros en lugares muy distantes entre sí, ha ganado aceptación la tesis según la cual G. venusta es rara localmente y difícil de encontrar, pero tiene una amplia distribución en el conjunto de la Amazonia.[8]

O xénero describiuno en 1912 o zoólogo británico especializado en mamíferos Oldfield Thomas, en Ann. Mag. Nat. Hist., ser. 8, 9: 239.[8]
A especie foi descrita no mesmo ano, e polo mesmo autor, en Ann. Mag. Nat. Hist., ser. 8, 9: 240.[2]
A especie, ademais de polonome que lle impuxo Thomas, e actualmente válido, coñeceuse tamén polos sinónimos:

L'opossum dalla coda a pennello (Glironia venusta, Thomas, 1912) è un mammifero della famiglia dei Didelphidae.
È un opossum di dimensioni medie: la lunghezza del corpo è tra 16 e 20 cm., il peso intorno ai 200 g. Il dorso è color cannella, mentre il lato ventrale è grigio chiaro. Due larghe strisce nere che attraversano gli occhi partendo dal naso formano una maschera caratteristica. Non vi è dimorfismo sessuale. La caratteristica che dà il nome comune alla specie è la folta coda, che con una lunghezza media di 20 cm è più lunga del corpo. Nelle femmine non vi è traccia di marsupio.
L'areale in figura è una ricostruzione congetturale basata sulle località (in Perù, Bolivia, Ecuador e Brasile orientale) in cui sono stati trovati i primi 9 esemplari noti. Tutti gli esemplari sono stati osservati nella foresta amazzonica, ad altitudini comprese tra 300 e 1000 m.
Ricerche recenti hanno incrementato il numero di osservazioni (circa una ventina) e l'areale presunto.[2]
Le abitudini sono poco note. Si ritiene che sia una specie notturna e arborea. L'ultima caratteristica è dedotta soprattutto dalla presenza di alluci opponibili. La dentatura poco specializzata e la dieta di specie prossime rende probabile che la specie sia onnivora.
La valutazione del rischio di estinzione e più in generale dello stato di conservazione di questo mammifero è complessa.
La Zoological Society of London, in base a criteri di unicità evolutiva e di esiguità della popolazione, considera Glironia venusta una delle 100 specie di mammiferi a maggiore rischio di estinzione. D'altra parte IUCN ha modificato una propria precedente valutazione di "vulnerabile" (del 1996) in "rischio minimo" (2008), ritenendo che il piccolissimo numero di esemplari catturati sia dovuto alla difficoltà della cattura stessa più che all'esiguità della popolazione.[1]

Plymsvanspungråtta (Glironia venusta) är ett däggdjur i familjen pungråttor (Didelphidae) och den enda arten i sitt släkte.
Djuret har en tät och ullig päls med en brun grundfärg. Två mörkbruna eller svarta strimmor i ansiktet påminner om en mask. Svansen är lite längre än övriga kroppen och bär med undantag av den nakna spetsen yviga hår. Individerna når en kroppslängd mellan 16 och 20 centimeter samt en svanslängd mellan 20 och 23 centimeter.[2]
Hittills har man bara hittat nio individer av arten, alla i regnskogar i Brasilien, Peru, Ecuador och Bolivia. På grund av kroppsbyggnaden (motsättlig tumme och gripsvans) antar man att den främst lever i träd.[2]
Det är nästan ingenting känt om artens levnadssätt. Det antas att den liksom andra pungråttor är aktiva på natten. Troligen lever individerna mest ensamma och är allätare.[2]
Trots att så få exemplar har hittats, listas arten av IUCN som livskraftig (least concern).[1]
Artens position i systematiken är inte helt utredd. Ofta betraktas den som nära släkting till ullpungråttorna och listas tillsammans med dessa i underfamiljen Caluromyinae.[3] Andra zoologer listar arten i en egen underfamilj, Glironiinae.
