Parantechinus apicalis is primarily insectivorous, eating whatever insects they can find. Being a generalist in this way may be advantageous due to fluctuating environmental conditions. Specifically P. apicalis has been found to eat grasshoppers (Orthoptera), cockroaches (Blattaria), beetles (Coleoptera), termites (Isoptera), and ants (Hymenoptera). Plant material, such as the berries of Rhagodia baccata, make up around 20% of its diet. Members of this species show no significant differences in their diet during different seasons.
Animal Foods: insects
Plant Foods: fruit; nectar
Primary Diet: carnivore (Insectivore )
On the mainland southern dibblers prey on insects and are often prey to larger mammals. On the islands southern dibblers face little danger of predation but compete with introduced house mice for food.
There are no known positive affects of Parantechinus apicalis on humans. They are a member of a unique fauna and may be of ecotourist interest because of their rarity.
Positive Impacts: ecotourism
There are no known adverse affects of Parantechinus apicalis on humans.
In 1902 southern dibblers were thought to be extinct but were rediscovered in 1967. They have been threatened by human development, habitat destruction and burning, and the introduction of foxes and cats. Southern dibblers are presently undergoing extensive conservation efforts including successful translocations of captive-bred individuals to Escape Island. Although this project is fairly new, initial success is high with three generations surviving after the initial relocation.
US Federal List: endangered
CITES: no special status
IUCN Red List of Threatened Species: endangered
Southern dibblers do vocalize, but vocalization is usually only heard during mating and plays no role in the attraction of mates. There is no other information on how P. apicalis communicates, perceives its environment, or attracts mates, but related species rely heavily on sight and smell.

Although once widespread throughout southwest Australia, today Parantechinus apicalis is only found in small populations on the mainland. Two larger populations have recently been found inhabiting Boullanger and Whitlock Islands in Jurien Bay in Western Australia.
Biogeographic Regions: australian (Native )
Southern dibblers on Whitlock Island prefer dense vegetation such as dunal scrubland and succulent heath. This may be due to the protection it provides from predators or an increased abundance of insect prey. Interestingly, when released from captivity into the wild they take refuge in seabird burrows. On Boullanger Island there seemed to be no preference of habitat as the entire island is fairly regular and has no trees.
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: desert or dune
In captivity and in the wild Parantechinus apicalis individuals live 2 to 3 years. Interestingly, on Boullanger Island males display semelparity where they die immediately after the breeding season. Extremely high energy demands during the breeding season, elevated levels of free corticosteroids in the blood, and related disease such as ulcers, anemia, and parasite infestation ultimately cause the death of males. Because mainland males survive for multiple breeding seasons, this male die-off could be environmentally determined. One possible explanation is the effect of nesting seabirds including bridled terns and white-faced storm petrels on resources. Seabirds affect nutrients in the soil; post-breeding survival is significantly higher on Whitlock Island which has many seabirds, 18 times more nutrients in the soil and a larger amount of insects.

Southern dibblers are small, with males averaging 145 mm in length and 60 to 100 g. Male southern dibblers found on the mainland are generally heavier than island individuals. Females are smaller at 140 mm average and 40 to 75 g. They have pointed snouts, long whiskers, and strong jaws with sharp teeth. There are also grooves on the pads of their feet which function in providing good traction. These, along with sharp claws, allow them a good grip on trees and rocks. Parantechinus apicalis has rather coarse fur with a freckled appearance. The fur is brownish grey above and grayish white with yellow underneath. They have hairy tapering tails and distinctive white rings around large eyes.
Range mass: 40 to 100 g.
Range length: 140 to 145 mm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry ; polymorphic
Sexual Dimorphism: male larger
The color of the fur of southern dibblers is their best camouflage. They are also able to move easily and with speed through dense vegetation and, for these reasons, have few natural predators. Mainland populations are heavily preyed upon by introduced red foxes and feral cats.
Known Predators:
Anti-predator Adaptations: cryptic
Typical behaviors prior to and during mating include sniffing of the cloacal and facial regions and rump by both the male and female. This behavior is common and increases in intensity as the female approaches estrous. Chases and attempted mountings are frequent. The male may chase the female or vice versa. Often the animals vocalize when they are chasing or attempting mountings. Mountings are initiated by the male and there are many attempts that are unsuccessful. Chasing and unsuccessful mountings may occur up to 15 days prior to copulation. Successful mountings involve the male clasping the female in a neck-grip and a single copulation may continue for a few hours.
Mating System: polygynandrous (promiscuous)
Paranechinus apicalis will mate throughout March and April. Although females are only able to breed once annually, males may be able to breed in multiple seasons. The gestation period for southern dibblers is long compared to other small dasyurids, 44 to 53 days. Once females give birth they carry up to eight young in a shallow pouch. The young are dependent on the female for 3 to 4 months and usually disperse in September and October, reaching sexual maturity in 10 to 11 months.
Breeding interval: Southern dibblers breed once yearly.
Breeding season: Breeding occurs from March to April.
Average number of offspring: 8.

Die Sprenkelbeutelmaus (Parantechinus apicalis), auch unter ihrem englischen Namen Dibbler bekannt, ist eine Beutelsäugerart aus der Familie der Raubbeutler (Dasyuridae).
Es handelt sich um mäuseähnliche Tiere, die eine Kopf-Rumpf-Länge von 14 bis 15 Zentimetern und ein Gewicht von 30 bis 100 Gramm erreichen. Ihr Fell ist an der Oberseite graubraun und mit weißen Haaren gesprenkelt, die Unterseite ist hellgrau und mit gelblichen Haaren durchsetzt. Der Schwanz ist mit langen Haaren bedeckt.
Diese Tiere leben in einem kleinen Gebiet im südwestlichen Western Australia, wo sie Heidegebiete bewohnen. Sie sind nachtaktiv und schlafen tagsüber in Blätternestern, die sie meist in hohlen Baumstämmen errichten. Ihre Nahrung dürfte hauptsächlich aus Insekten bestehen, vermutlich nehmen sie aber auch Nektar zu sich. Nach 44- bis 53-tägiger Tragzeit bringt das Weibchen bis zu acht Jungtiere zur Welt, die mit drei bis vier Monaten selbständig werden und mit zehn bis elf Monaten die Geschlechtsreife erreichen. Berichte deuten an, dass es bei ihnen wie bei den Breitfuß-Beutelmäusen zu einem synchronen Sterben aller Männchen nach der ersten Paarung kommen könnte.
Südliche Sprenkelbeutelmäuse sind bedroht, die Gründe dafür liegen in der Zerstörung ihres Lebensraumes und der Nachstellung durch eingeschleppte Räuber wie Hauskatzen oder Füchse. Gesicherte Populationen gibt es nur auf zwei kleinen Inseln vor der Küste Westaustraliens (Boullanger- und Whitlock-Insel), auf dem Festland werden immer wieder vereinzelte Tiere gesichtet, so dass eine genaue Angabe über das Verbreitungsgebiet nicht möglich ist. Die IUCN listet die Art als „stark gefährdet“ (endangered) und schätzt den Gesamtbestand auf 500 bis 1000 Individuen.
Der Perth Zoo unterhält seit 1997 ein Programm zur Erhaltungszucht und Auswilderung von Sprenkelbeutelmäusen. Bis Anfang 2007 wurden bereits 418 im Zoo geborene Sprenkelbeutelmäuse ausgewildert, die meisten auf Escape Island in der Jurien Bay (in der auch die Boullanger- und Whitlock-Insel liegen).
Früher wurde eine zweite Art, Parantechinus bilarni, aus dem nördlichen Northern Territory ebenfalls in diese Gattung gestellt, nach neueren Untersuchungen dürfte sie jedoch zur Gattung der Fettschwanz-Beutelmäuse (Pseudantechinus) gehören.

The dibbler (Parantechinus apicalis) is an endangered species of marsupial. It is an inhabitant of the southwest mainland of Western Australia and some offshore islands. It is a member of the order Dasyuromorphia, and the only member of the genus Parantechinus. The dibbler is a small, nocturnal carnivore with speckled fur that is white around the eyes.
The dibbler is 10–16 cm (3.9–6.3 in) long with a 7.5–12 cm (3.0–4.7 in) tail; it weighs 40–125 g (1.4–4.4 oz). Distinctive features include a white eye-ring, gray-brown fur flecked with white hairs, and a short tapering tail. It has strong jaws and large canine teeth for killing prey, which include small vertebrates such as mice, birds and lizards, as well as insects and other invertebrates. They are semi-arboreal and will also feed on nectar from flowering plants and berries. Dibblers weigh about 40–135 grams (1.4–3.6 oz).The breeding season for the species is March–April, with the female able to give birth and raise up to eight young. The dibbler is a solitary, mostly crepuscular species.
The dibbler is found in southwestern Western Australia, where it is located on Boullanger Island, Whitlock Island and Escape Island (translocated) off Jurien Bay.[2] They are also found on the South Coast in the Fitzgerald River National Park, Peniup Proposed Nature Reserve (where it was re-introduced) and on Gunton Island in the Recherche Archipelago (where it was also re-introduced). They have also recently been released on Dirk Hartog Island as part of the Return to 1616 project run by the Department of Biodiversity, Conservation and Attractions. There were attempted releases at the Stirling Range National Park and Waychinicup National Park but it is not thought that they still persist in those locations. A specimen was also captured in Torndirrup National Park south of Albany.
The dibbler's habitat is an unburnt vegetation area with a thick litter layer and sandy soils, typically occupying coastal mallee-heath vegetation communities on the south coast.
The dibbler is the only member of its genus, Parantechinus, which indicates that it is an "antechinus-like (animal)".[3] The specific epithet, apicalis, means "pointed". This genus formerly included the sandstone dibbler, now placed in the genus Pseudantechinus.
The genus Parantechinus contains only the single species, Parantechinus apicalis, the dibbler. It was first described in 1842 by John Edward Gray, who placed it in the genus Phascogale. He identified the specimen as being Australasian in origin. The genus Parantechinus was created for the species in 1947 by George Henry Hamilton Tate. The species was also assigned to the genus Antechinus, before being split to its own genus. There are various arrangements of the genera in this section of family Dasyuridae, many of which are supported by molecular systematics, and their relationship remains unresolved.[4]
The name 'dibbler' is used by government and scientific authorities, and in popular usage, to refer to this species exclusively.[5][6][7][8] In the Dibbler Recovery Plan, Senior DBCA scientist, Dr. Tony Friend notes
Strahan (2003) introduced the common name "southern dibbler" for P. apicalis [Parantechinus apicalis] and "northern dibbler" for the sandstone antechinus" [Pseudantechinus bilarni][4] ... the well-established use of "dibbler" to refer only to P. apicalis is recommended and is followed in this plan."[9]
A number of common names derive from previous systematic arrangements. John Gould gave several names from the Nyoongar/Noongar language; Marn-dern and Wy-a-lung are from northern areas, Dib-bler is from the dialect spoken in the King George Sound region.[10] The practice of restoring traditional names to marsupial species has conserved this common name. Gould referred to the species as the freckled antechinus,[4] and it has also been known as the speckled marsupial mouse.
The online edition of Mammal Species of the World gave the name Southern dibbler in 2009.[11] A species known as the Northern (or sandstone) dibbler, Pseudantechinus bilarni, is found in the Northern Territory. This species has been distinguished by the name Southern dibbler, however this name is given in The Mammals of Australia (2008),[12] the formative guide for Australian mammal nomenclature worldwide.
In the early 19th century, dibblers were widely distributed across Western Australia. By 1884, they were declared extinct, but some were rediscovered at Cheyne Beach on the southern coast of Western Australia in 1967. They are threatened by habitat loss (land clearing, dieback) and predators; they are considered an endangered species. Their predators are mainly feral foxes and feral cats.
Perth Zoo in Western Australia operates a conservation project for the dibbler which is helpful in its survival and breeding, and along with the Department of Environment and Conservation has helped to breed and release more dibblers into the wild.

El díbler meridional (Parantechinus apicalis) es una especie de marsupial dasiuromorfo de la familia Dasyuridae endémica de Australia.
Puede encontrarse en el terrenos arenosos con densa cubierta de matorral al suroeste de Australia Occidental y algunas islas cercanas a la costa como Boullanger y Whitlock, aunque hallazgos fósiles indican que este animal pudo vivir en otro tiempo en territorios más orientales de Australia.
El cuerpo es pequeño y rechoncho, parecido al de un ratón. Pesa 60-100 g y mide 14 cm de longitud más 11 cm de cola. Está cubierto de pelo corto pardo grisáceo salpicado de blanco en las regiones dorsales y más claro en las ventrales, gris con tintes amarillentos.
Las orejas son grandes y puntiagudas. Los ojos, también grandes, negros y redondos, con un anillo blanco alrededor de cada uno de ellos. El hocico es acuminado y está dotado de bigotes desarrollados. La boca está armada con pequeños dientes afilados que indican hábitos carnívoros.
Los pies son anchos, las almohadillas plantares presentan marcados surcos que les permiten trepar a árboles y escalar rocas. Los dedos terminan en afiladas uñas.
El marsupio de las hembras consiste en un simple pliegue de la piel abdominal en cuyo interior se albergan ocho mamas.
Son mayoritariamente carnívoros, alimentándose de mamíferos, aves y reptiles de pequeño tamaño. Complementan su dieta con grandes insectos terrestres y polen de distintas flores e incluso miel.
La época de celo va de marzo y abril. El periodo de gestación es de 44 días. Las hembras son monoéstricas y paren camadas de 8 o más crías. La madurez sexual se alcanza aproximadamente al año de edad. En libertad, la esperanza de vida es de 3 años.
Son animales nocturnos que pasan las horas de luz cobijados en grietas entre las rocas, agujeros de troncos caídos y cuevas o galerías abandonadas.

Parantechinus apicalis est une espèce de marsupiaux de la famille des Dasyuridae.
La reproduction a lieu de mars à avril. La gestation dure de 44 à 53 jours ce qui est long comparé aux autres Dasyuridae. La femelle a en moyenne huit petits par portée qu'elle garde dans sa poche. Les petits sont dépendants de leur mère pendant trois à quatre mois et la quittent entre septembre et octobre. Ils acquièrent la maturité sexuelle entre 10 et 11 mois[1].
Parantechinus apicalis est une espèce de marsupiaux de la famille des Dasyuridae.
Il dibbler (Parantechinus apicalis Gray, 1842), noto anche come topo marsupiale macchiato, è un marsupiale della famiglia dei Dasiuridi[2]. Unica specie del genere Parantechinus Tate, 1947, è uno dei mammiferi più rari del mondo.
Il dibbler ha una lunghezza testa-corpo di 14 cm e una coda di 8-11 cm; pesa 40-100 g. Come altri membri della famiglia dei Dasiuridi, ha un caratteristico muso appuntito, canini ben sviluppati, 6-7 denti posteriori affilati e grossi piedi muniti di artigli aguzzi. Il piccolo corpo muriforme è ricoperto da un'ispida pelliccia di colore grigio-brunastro, con caratteristiche brizzolature bianche. La coda è pelosa e affusolata, e attorno agli occhi vi sono due caratteristici anelli bianchi. Le femmine, come quelle della maggior parte dei marsupiali, trasportano i piccoli nel marsupio fino a che non sono pienamente sviluppati[3].
I dibbler sono attivi perlopiù all'alba e al crepuscolo. Si nutrono di insetti terricoli e di altri invertebrati, ma catturano anche piccole lucertole, uccellini e piccoli mammiferi. Sono carnivori ben adattati, muniti di mascelle robuste e minuscoli denti affilati; sono inoltre incredibilmente agili e sono in grado di correre facilmente anche nel sottobosco più impenetrabile. Non sono solo equipaggiati per cacciare sul terreno, ma sono anche capaci di correre lungo alberi e rocce. I piedi, molto larghi e muniti di artigli, presentano delle pieghe sui cuscinetti plantari che agiscono da ventose[3].
Le femmine hanno un ciclo estrale all'anno, e si accoppiano in marzo o aprile. Dopo una gestazione di 44 giorni, partoriscono fino a 8 piccoli. Questi ultimi rimangono nel marsupio materno per alcune settimane, finché non divengono troppo grandi[3].
Il dibbler è endemico dell'Australia sud-occidentale. In natura è presente unicamente nel parco nazionale del Fiume Fitzgerald e sulle isole di Boullanger e Whitlock, ma è stato reintrodotto sull'isola di Escape e nei parchi nazionali di Peniup e Stirling Range[1].
Predilige le macchie con folto sottobosco e suolo sabbioso, nel quale scava tane e cavità in cui riposa durante il giorno[1].
Il dibbler è l'unico membro del suo genere, Parantechinus («[animale] simile a un antechino»)[4]. Il nome specifico, apicalis, significa «appuntito». In passato in questo genere veniva classificato anche lo pseudantechino delle sabbie, posto attualmente in Pseudantechinus.
Il dibbler è uno dei mammiferi più rari del mondo. Fossili risalenti a epoche recenti indicano che in passato il suo areale si spingeva verso nord fino alla baia degli Squali, sulle coste centro-occidentali dell'Australia Occidentale, ma non veniva più catturato da 83 anni quando, nel 1967, due esemplari vennero presi vivi all'estremità sud-occidentale di questo Stato. Nonostante molteplici tentativi, fino al 1984 ne vennero catturati solamente altri sette esemplari, e altri due vennero trovati morti. La distruzione dell'habitat per fare spazio a terreni agricoli è stata di gran lunga responsabile del declino subito dalla specie in passato, ma ora una riserva di 75 ha protegge il luogo dove il dibbler è stato riscoperto. Nel 1984 un altro esemplare morto venne trovato nel parco nazionale del Fiume Fitzgerald, lungo le coste meridionali dell'Australia Occidentale, e successivamente altri 14 individui furono catturati vivi con trappole nello stesso parco o nei suoi pressi. Nel frattempo, nel 1985 un gran numero di esemplari venne scoperto sulle isole di Boullanger e Whitlock, al largo delle coste occidentali. La IUCN classifica la specie nella categoria «in pericolo» (Endangered)[1].

De gespikkelde buidelmuis of dibbler (Parantechinus apicalis) is een buidelmuis uit de geslachtengroep Dasyurini. Het is de enige soort in het geslacht Parantechinus, dat waarschijnlijk verwant is aan Dasykaluta. Dit geslacht werd eerder tot Antechinus gerekend.
De gespikkelde buidelmuis heeft een behaarde, bij de basis brede, taps toelopende staart en korte, behaarde oren. De bovenkant is bruin met vele lichte vlekken. De flanken zijn kaneelkleurig en gaan over in de geelgrijze onderkant. De voeten zijn roodgrijs. De kop-romplengte bedraagt 140 tot 145 mm, de staartlengte 90 tot 115 mm en het gewicht 40 tot 100 g.
Deze soort is solitair en 's nachts actief. Het dier eet ongewervelden en kleine gewervelden (vogeltjes, muizen, hagedissen), die meestal tussen oude bladeren worden gevonden. Soms klimt het dier ook in struiken om insecten en nectar te vinden. De paartijd is in maart en april.
In de twintigste eeuw werd lange tijd aangenomen dat de gespikkelde buidelmuis was uitgestorven. In 1967 werd de soort echter na 83 jaar niet te zijn gezien herontdekt. Fotograaf Michael Morcombe zag twee gespikkelde buidelmuizen bij Cheyne Beach aan de zuidkust van West-Australië. In 1985 werd een nieuwe populatie ontdekt, ditmaal op twee van de eilanden van Jurien Bay in West-Australië. Eén mannetje dat geobserveerd werd, bleek in vier dagen tijd met zes vrouwelijke dieren te paren. Alle mannelijke gespikkelde buidelmuizen stierven aan het einde van de paartijd, waarschijnlijk ten gevolge van een overmatige stressreactie zoals die ook bij andere buidelmuizen (breedvoetbuidelmuizen, penseelstaartbuidelmuizen) wordt gezien.
Deze soort komt voor in gematigde bossen of bosachtige terreinen langs de kust van zuidwestelijk West-Australië van het Nationale park Fitzgerald River tot het Nationale park Torndirrup, en ook op de eilanden Boulenger en Whitlock.

Parantechinus apicalis är ett däggdjur i familjen rovpungdjur (Dasyuridae).
Arten påminner i utseende om en mus och når en kroppslängd (huvud och bål) mellan 14 och 15 centimeter samt en vikt mellan 30 och 100 gram.[2] Därtill kommer en cirka 10 cm lång svans. Pälsen är på ovansidan gråbrun men enstaka glest fördelade vita hår, undersidan är ljusgrå med några gulaktiga hår. Även svansen är täckt med långa hår.[2] Kännetecknande är vita ringar kring ögonen.[2] Honans pung (marsupium) bildas av flera hudflikar och har åtta spenar.[2]
Individerna lever i ett område med hed i sydvästra Western Australia samt på öar i närheten. De är aktiva på natten och sover på dagen i bon av blad som vanligen göms i trädens håligheter.[2] Ibland vaknar de och solbadar. Födan består troligen främst av insekter och i mindre mått av nektar.[2] Dräktigheten varar i 44 till 53 dagar och sedan föder honan upp till åtta ungar. Ungarna blir efter tre till fyra månader självständiga och efter tio till elva månader könsmogna. Enligt obekräftade berättelser dör alla hannar efter den första parningen, liksom hos pungspetsekorrar.[2]
Populationen på Australiens fastland hotas av förstöringen av levnadsområdet samt av införda rovdjur som rävar och katter. Säkra bestånd finns bara på två öar nära Australiens kustlinje, Boullanger Island och Whitlock Island. IUCN listar arten som stark hotad och uppskattar hela populationen med 500 till 1000 individer[1]. Tidvis antogs att arten var utdöd[3].
Hos djurparken i Perth pågår sedan 1997 ett avelsprogram så att flera individer kan återinföras i naturen. Fram till 2007 återinfördes 418 individer från djurparken, de flesta på Escape Island.
Tidigare listades ytterligare en art i samma släkte, Parantechinus bilarni[2], som förekommer i Northern Territory. Efter nyare undersökningar listas den numera i släktet Pseudantechinus.[4]

Parantechinus apicalis är ett däggdjur i familjen rovpungdjur (Dasyuridae).
Ендемік південно-західної Австралії. Живе у чагарниках і пустищах. Їсть різних членистоногих, та деяких дрібних хребетних.
Морфометрія. Довжина голови й тіла: 140—145 мм, довжина хвоста: 95—115 мм, вага 30—100 гр.
Опис. Забарвлення коричнювато-сіре з білими цяточками на верхніх частинах тіла і сірувато-біле з жовтуватим відтінком на нижніх частинах тіла. Самиці мають вісім молочних залоз. Самиці можуть народжувати до восьми дитинчат. Дітонародження може відбуватись двічі на рік. Вагітність триває 44-53 дні. Діти стають незалежними у 3-4 місяці, досягають статевої зрілості в 10-11 місяців.
Лисиця та кіт полюють на цей вид. Поширення рослини Phytophthora cinnamomi є загрозою так як несприятливо змінює середовище проживання. Введена миша є загрозою через конкуренцію. Часті й інтенсивні пожежі є ще одними суттєвими загрозами. Трапляється в кількох природоохоронних територіях.

Синонимы
Крапчатая сумчатая мышь[1] (лат. Parantechinus apicalis) — единственный вид из рода крапчатых сумчатых мышей семейства хищные сумчатые. Эндемик Австралии.
Обитает в юго-западной части Австралии на территории штата Западная Австралия. Встречается на территории национального парка Фицджералд-Ривер, а также на прибрежных островах Буллангер и Уитлок. Реинтродуцирован на острова Эскейп, Пениап, а также на территорию национального парка Стерлинг-Рейндж[2].
Естественная среда обитания — местности, густо покрытые кустарниками и суккулентами[2]. Вероятно, выбор этой среды вызван тем, что она обеспечивает защиту от хищников и характеризуется обилием насекомых, составляющих основу рациона этого вида[3].
Длина тела с головой колеблется от 120 до 140 мм, хвоста — от 90 до 110 мм. Вес варьирует от 40 до 100 г[4]. Экземпляры, найденные на континентальной части Австралии, как правило, превосходят по размерам островные экземпляры. Кроме того, между самцами и самками существует половой диморфизм: самцы крупнее и тяжелее самок. Морда заострённая. Вибриссы длинные. На лапках имеются небольшие желобки, основная функция которых — обеспечивать хорошее сцепление со стволами деревьем и скалистой землёй[3]. Волосяной покров относительно грубый. Окрас спины — буро-серый, брюха — серовато-белый с жёлтым оттенком. Хвост покрыт волосяным покровом, сужается к концу. Вокруг глаз расположены белые круги[3].
Проявляют активность как на рассвете, так и во время сумерек. Ведут, как правило, наземный образ жизни, однако запросто могут лазить по деревьям в поисках еды. Днём прячутся в укрытиях — в норах или расщелинах между скал. Основу рациона составляют насекомые. Питаются также растениями. К примеру, ягоды растения лат. Rhagodia baccata составляют до 20 % рациона[3].
У самки имеется сумка, которая больше похожа на складку кожи поверх сосков[5]. Период размножения приходится на март-апрель. Совокупление самца и самки может продолжаться несколько часов[3]. Перед этим поведение самца становится агрессивным, а сам он на протяжении нескольких дней (до 15 дней) занимается поисками подходящей самки. Самки могут приносить потомство только раз в год, в то время как самцы могут оплодотворять несколько раз в год. Беременность в сравнении с другими хищными сумчатыми продолжительная, длится от 44 до 53 дней[3]. В потомстве до 8 детёнышей. От груди отлучаются через 122 дня. Половая зрелость наступает примерно через 315 дней. Максимальная продолжительность жизни в неволе — 5,5 лет (в природе — более 3 лет)[6]. Самцы с острова Буллангер умирают вскоре после оплодотворения самки. Самцы с континентальной Австралии продолжают жить[3].
