the sandstone false antechinus , pseudantechinus bilarni , also known as the sandstone pseudantechinus , the sandstone antechinus , the sandstone dibbler , harney 's antechinus and the northern dibbler , is a species of small carnivorous marsupial , which has a patchy distribution in australia 's northern territory .

sandstone false antechinus

sandstone false antechinus <EOT> some sources give the vernacular name for this genus as “false antechinus” ( e . g . menkhorst 2001 ) , thus carpentarian false antechinus for p . mimulus . this formation provides somewhat greater taxonomic precision but is unnecessarily cumbersome .

museum specimens of the carpentarian antechinus may have been incorrectly identified as the fat - tailed antechinus ( pseudantechinus macdonnellensis ) ( woolley 2011 ) .

[ 3 ] a member of the family dasyuridae , the yellow - footed antechinus is the most widespread of all the members of its genus , antechinus . three subspecies of the yellow - footed antechinus are recognised :

the carpentarian antechinus has been recorded in rocky areas and nearby woodland . in central queensland it has been found on sandstone , granite , metamorphic and igneous geology ( lloyd et al . 2013 ; woolley 2011 ) . specific habitat descriptions include :

the carpentarian antechinus occurs at pungalina - seven emu , which is an australian wildlife conservancy property .

the yellow - footed antechinus ( antechinus flavipes ) , also known as the mardo , is a shrew - like marsupial found in australia . one notable feature of the species is its sexual behavior . the male yellow - footed antechinus engages in such frenzied mating that it ' s immune system becomes compromised , resulting in

the extent of occurrence of the carpentarian antechinus is 16 000 km² ( curtis et al . 2012 ) .

sandstone false antchinus are endemic to the area and they can crop up anywhere with massive sandstone boulders and rock sheets . nourlangie is one spot to look , and koolpin gorge is another ( koolpin is one of the nicest public campsites in kakadu ; you need to arrange a permit beforehand to stay there , which is easily done through the parks office ) . the road into koolpin is one of the best areas of the park for kakadu pebble mound mice . i’ve looked but never seen them there – they live on the pebble strewn slopes on either side of the road in . they’ve also been reported from quite near gunlom campsite ( a few kilometres before you get to gunlom you cross plum tree creek . try looking around there ) .

the sandstone antechinus is associated particularly with areas with large boulders , crevices , and scree slopes ( begg 1981 ) , but shows no close association with vegetation features ( begg 1981 , fisher et al . 2000 ) . the sandstone antechinus is a nocturnal , generalist predator of invertebrates and small vertebrates . it is restricted to rugged rocky environments . in the 12 months following a high intensity experimental fire at the little nourlangie rock site , survivorship decreased ( relative to pre - fire estimates ) , and the total population size declined ( begg et al . 1981 ) . breeding is seasonal , with young born in august and september ( begg 1981 ) . females have six nipples , but the number of young produced is typically less than this capacity ( begg 1981 ) .

taxonomythe yellow - footed antechinus was described in 1838 by george robert waterhouse , who noted its most distinctive feature in its species name flavipes , which means " yellow - footed " . the species has occasionally been combined with the brown antechinus ( a . stuartii ) .

in november 2003 , aboriginal rangers from mubanji participated in collaborative surveys for carpentarian antechinus with scientists from the nt department of infrastructure planning and environment .

targeted management for northern hopping - mouse , carpentarian antechinus and butlers dunnart will benefit these other mammal species . the management actions with broadest collateral benefit are :

[ 3 ] in size and body shape this species is fairly typical of its genus . the yellow - footed antechinus differs from its relatives in its comparatively

descriptionthe yellow - footed antechinus has a variable fur colour , but is generally somewhat greyish . other notable features include a white eye - ring and a black tip to the tail .

there are no data available on the diet of carpentarian antechinus in the wild , but captives consume invertebrates and possibly small vertebrates ( johnson et al . 2008 ; johnson & langford 1995 ) .

the threats affecting the carpentarian antechinus are unknown . the feral cat ( felis catus ) probably predates the species , but its rocky habitat probably provides some protection ( curtis et al . 2012 ) . fire regimes in northern australia have shifted to hot , extensive late dry season fires , and , although it is unlikely that these cause direct mortality to the carpentarian antechinus , they may impact on the abundance and availability of their prey ( curtis et al . 2012 ) .

the national recovery plan for the carpentarian antechinus , butler ' s dunnart ( sminthopsis butleri ) and northern hopping - mouse ( notomys aquilo ) ( woinarski 2004 ) outlines recovery actions for the carpentarian antechinus with the aim of better communicating information about the species to stakeholders . a review of the plan in 2010 indicated that a number of activities , within the range of the species , have been initiated to abate threats associated with fire , the feral cat and information deficiencies ( dsewpac 2011ae ) .

much of the range of all three species is on aboriginal lands : indeed , all recent records of butlers dunnart and northern hopping - mouse are on aboriginal lands . in the northern territory , the interests managing these lands are the tiwi land council ( butlers dunnart ) , anindilyakwa land council ( northern hopping - mouse ) , northern land council ( northern hopping - mouse and carpentarian antechinus ) , dhimurru aboriginal land management corporation ( northern hopping - mouse ) and mubanji aboriginal resource association ( carpentarian antechinus ) .

details of the microhabitat and breeding requirements of the carpentarian antechinus are unknown . the species occurs in rocky areas such as ridgelines , rock outcrops , jump - ups and boulder piles ( baam 2010 ) and is thought to hide in rock crevices during the day ( johnson et al . 2008 ) .

parts of the range of the northern hopping - mouse occurs on lands subject to extensive strip - mining , for bauxite at gove , and for manganese on groote eylandt . the first records of the carpentarian antechinus in queensland were during a survey of the impacts of sulphur dioxide emissions around the mt isa mine ( griffiths 1998 ) .

black wallaroos , endemic to the arnhem land sandstone country , are findable in the right areas . i saw one up above gunlom falls ( in the middle of the afternoon ) and another while i was spotlighting on top of little nourlangie . there are antilopine wallaroos too , try looking around the gimbat area . wikins’ ( formerly short - eared ) rock wallabies are quite easy to see around ubirr , while narbaleks might be possible , or so i have been told , near the jim jim falls campsite ( i have never made it there – access is difficult until quite late in the dry season and then restricted to 4wd ) .

in queensland , the provenance of the single old record of northern hopping - mouse is so vague that it cannot be assigned with any confidence to any land tenure category , but may be in either aboriginal lands , pastoral lands , conservation reserves and / or lands managed by defence . the few recent records of carpentarian antechinus from queensland are in pastoral leasehold and freehold lands .

victoria . isolated populations occur in northeastern queensland and in southwestern western australia . some populations are listed as " locally common " , others as uncertain . the yellow - footed antechinus occupies a variety of habitats , including dry arid scrubland and sclerophyll forest . in the north , it also inhabits coastal heaths , swamps and woodland ; in the far north it is found in tropical vine forest .

the carpentarian antechinus is a small , carnivorous marsupial with brown fur , a reddish patch behind the ears and a white underside . body length is 70–90 mm , tail length is 60–75 mm and weight is 15–25 g ( curtis et al . 2012 ; strahan 1998 ) . males are smaller than females . species in the genus pseudantechinus store fat in their tail , and this becomes carrot - shaped when food is plentiful ( woinarski 2004 ) .

butlers dunnart sminthopsis butleri is another small ( ca . 10 - 20 g . ) terrestrial carnivorous marsupial , finer of features than for the carpentarian antechinus . it too is similar in general appearance to a range of small dasyurids occurring across australia , including the kakadu dunnart s . bindi and red - cheeked dunnart s . virginiae in northern australia . all are generally grey - brown above and pale below , with large ears and eyes , and sharply pointed muzzle .

the carpentarian antechinus occurs in the sir edward pellew group of islands ( centre , north , south - west and vanderlin islands ) in the nt ( curtis et al . 2012 ; kitchener 1991 ) , the pungalina - seven emu area on the mainland in the nt ( nt government 2011 ) , along the selwyn range south of cloncurry in queensland ( baam 2011 ; lloyd et al . 2013 ) and on a number ridges around mt isa in queensland ( baam 2011 ; lloyd et al . 2013 ; woolley 2011 ) . the species was originally collected on alexandria station in the nt , in 1905 , but has not been recorded there since ( maxwell et al . 1996 ) .

thank you for taking the time to provide feedback on the iucn red list of threatened species website , we are grateful for your input .

according to groves in wilson and reeder ( 1993 ) and nowak ( 1999 ) parantechinus bilarni is a good species . however , this species has been transferred to pseudantechinus following the australasian marsupial specialist group ( maxwell et al . 1996 ) .

justification : population size is poorly resolved but likely to be between 10 , 000 and 30 , 000 individuals ; monitoring results provide inconsistent indication of population trends , but a plausible rate of decline is 10 - 20 % over 10 years ; habitat quality is likely to be subject to ongoing decline , but management actions are having some beneficial impact on main threat ( fire ) . it does not fit criteria for threatened ; a categorisation of near threatened may be valid but population size and rate of decline are poorly defined and unlikely to approach relevant thresholds .

the species is present in several protected areas , notably including kakadu national park . there is some fire management in this and other reserves , which may have led to some recent improvements , but current regime is still characterised by frequent , high intensity and extensive fires .

this plan jointly considers three native mammal species from northern australia . while the three species share some similarities in ecology , status and conservation management requirements , there are also distinct differences among them in these and other features . recognising both these similarities and differences , this plan follows the standard overall framework for single species recovery plans , but provides specific information for each of the three species whenever relevant throughout , and wherever possible pools information from each of the three species accounts to derive commonalities and to highlight management issues and actions that may apply for all three species .

the northern hopping - mouse notomys aquilo is a medium - sized ( 25 - 50 g . ) terrestrial granivorous rodent . it has features typical of hopping - mice in general , with very long narrow hindfeet , large ears and eyes , and very long partly tufted tail ( about 150 % of head - body length ) . it is the only representative of its genus in northern australia , thus , in this area , its morphology is highly distinctive . it is sandy - brown above and paler below . hopping - mice move with a distinctive gait , such that the bipedal tracks may provide the most conspicuous signs of its presence .

the three species each have a somewhat complicated taxonomic history , notable for single puzzling early records followed by a long period before any subsequent specimens .

butlers dunnart sminthopsis butleri archer , 1979 was described relatively recently ( archer 1979 a ) ( with the vernacular name carpentarian dunnart : archer 1979 b ) , on the basis of one specimen collected on “cape york” in 1898 and three specimens from kalumburu wa collected in 1965 and 1966 .

a further historical record ( previously mis - identified as s . virginiae ) , collected on melville island in 1913 , was subsequently assigned to this species ( woinarski et al . 1996 ) . since the original description , examination of additional specimens from cape york peninsula and new guinea resulted in a taxonomic split of s . butleri , with that taxon now referring to only those populations from the northern nt and kimberley , and the queensland and new guinea population defined as the carpentarian dunnart s . archeri ( van dyck 1986 ) . given this treatment , the listing of “carpentarian dunnart sminthopsis butleri ” as a threatened species under the epbca is invalid and confusing . the listing should be of butlers dunnart s . butleri .

the northern hopping - mouse notomys aquilo thomas 1921 was described from a single specimen collected around the 1870s from “cape york” . the species was not reported again until johnson ( 1959 , 1964 ) named n . carpentarius from 13 specimens collected on groote eylandt , northern territory in 1948 . in this description , johnson did not compare this series with the type of n . aquilo , and he was apparently also unaware that donald thomson had also collected hopping - mice on groote eylandt some five years previously ( i . e . 1943 - 1944 : with these records not documented until much later : dixon and huxley 1985 ) . subsequent comparisons revealed the conspecificity of n . carpentarius with n . aquilo ( ride 1970 ) .

schedule 1 - fauna that is rare or likely to become extinct in western australia , under the wildlife conservation ( specially protected fauna ) notice 2003 ( wildlife conservation act 1950 ) .

in each case , the nt status is based on evaluations made in 2003 . the national status typically follows assessments made in the action plans for australian rodents ( lee 1995 ) and marsupials and monotremes ( maxwell et al . 1996 ) .

the primary affected interests for all three species are the australian and state / territory conservation agencies , and particularly that of the northern territory , in which the bulk of the range for all three species occurs .

in western australia , the kimberley land council and wunambal - gaambera aboriginal corporation manages those lands near kalumburu on which butlers dunnart was recorded .

on melville island , butlers dunnart occurs in sites either in or around a developing major forestry venture ( oprated by sylvatech ) that replaces native vegetation with short - rotation exotic plantation species .

thomson ( in dixon and huxley 1985 ) also noted that many aboriginal people appeared to have very little knowledge of northern hopping - mouse , even in sites where it appeared to be relatively common .

aboriginal rangers from dhimurru aboriginal land management corporation have conducted searches for northern hopping - mice at nanydjaka ( cape arnhem ) ipa .

there is some proximity in distribution between the three species considered here and the golden bandicoot isoodon auratus and golden - backed tree - rat mesembriomys macrurus , both considered vulnerable at national level .

such actions will benefit not only the three mammal species considered here and at least some of the other mammals listed above , but will also have benefits for some co - occurring bird species ( such as the vulnerable partridge pigeon geophaps smithii : fraser et al . 2003 ) and , with less substantial evidence , a gamut of other plant and animal species that have been adversely affected by recent changes in fire regimes ( e . g . bowman and panton 1993 ; russell - smith et al . 1998 , 2002 ; franklin 1999 ; bowman et al . 2001 ; yibarbuk et al . 2001 ) .

there are no clearcut and tightly defined social and economic impacts associated with this recovery plan . much of the distribution of these three species is on aboriginal land . research on , and management of , these species may provide some limited contributions to these local economies . the three species each have some distributional overlap or convergence with large mining or forestry operations . conservation management for the species may come at some costs to these ventures , but such costs are generally likely to be low because the disturbances are generally not on lands that provide high quality habitat to these species . a possible exception is for butlers dunnart on melville island , where forestry development may occur on , or be proposed for , habitats that have high suitability for this species .

for information to assist regulatory considerations , refer to policy statements and guidelines , the conservation advice , the listing advice and / or the recovery plan .

recovery plan required , this species had a recovery plan in force at the time the legislation provided for the minister to decide whether or not to have a recovery plan ( 19 / 2 / 2007 ) . the recovery plan ( woinarski 2004 ) that was adopted for this species on 10 / 06 / 2005 ceased to be in effect from 1 / 10 / 2015 .

the targeted assessment for the copper string environment impact statement ( eis ) involved a 10 day habitat assessment survey that preceded four trapping surveys ( baam 2011 ) . the habitat assessment was used to select the most suitable sites for four 5 - day trapping surveys . the trapping records , together with the previous records in the vicinity of the study area ( woolley 2011 ) , were incorporated into the habitat mapping methodology to map known important habitat and potential habitat for the species within the study area ( baam 2011 ) .

the breeding season is thought to be short occurring some time between august and october ( curts et al . 2012 ) . similar species have a litter size of 4–6 and it is likely that some males and females survive to breed in a second year ( curtis et al . 2012 ) . of seven females caught during july and august 1988 , none had pouch young ( johnson & langford 1995 ) .

buffel grass invasion could significantly change the ecology of the central queensland ridges where the species occurs ( lloyd et al . 2013 ) .

the mabunji aboriginal resource association received $ 25 000 of funding , through the threatened species network community grants in 2004–05 for the establishment of a monitoring program for this species on the sir edward pellew islands .

myoictis is a genus of marsupials in the order dasyuromorphia . it is found in new guinea .

the taxonomy for the specie was difficult for most biologist to understand . woolley proposed the names the four different species by recognizing the animal by the morphological differences . while also using genetic testing , scientist have found that the myoictis melas and the myoictis wallacei contain a sequence divergence of 12 . 85 % .

each of the four species were found to have significant physical differences between them . the myoictis wavicus averages roughly 122 grams , the myoictis wallacei averages roughly 230 grams , the myoictis leucura averages roughly 220 grams , and the myoictis melas averages roughly 220 grams . the proportions of head and limb size were also found to be smaller with the smaller mass .

the myoictis leucura , or woolley ' s three - striped dasyure was recently described being genetically and morphologically distinct from the other members of the genus myoictis . it is more similar to the m . wavicus .

between 1894 and 1895 , the myoictis leucura was found in papua new guinea , the southern side of the central cordillera . it normally lives in elevations between 650 meters and 1600 meters . the species inhabits mostly lowland and montane forest . peter dwyer has found the species to be active during the daytime and being mostly terrestrial .

kultarrs are small and mouse - like in appearance . the pelt is grey to sandy brown , and the long tail has brush - like dark hairs on the sides . the dark coloring around the eyes , mid - line , and top of the head varies among individuals . they are primarily nocturnal and , as such , have large round eyes and enlarged ears . they have elongated hind feet with four independent digits .

kultarrs weigh 20 to 30 g and measure 170 to 200 mm in length . they exhibit sexual dimorphism with males being about 15 mm longer and 10 g heavier than females .

kultarrs inhabit : open shrubland , mallee woodland , acacia shrubland with sparse ground cover , hummock grassland , gibber , flood plains , and stony areas with sparse ground cover . the species generally prefers heavier soil types ( maxwell et al . 1996 ) . kultarrs have been recorded on severely degraded cattle country in central and western australia but this may reflect the previous relatively high productivity of these landscape types rather than any benign effect of cattle ( maxwell et al . 1996 ) .

kultarrs inhabit arid to semi - arid plains . they prefer heavy soils including stoney , sandy , or clay filled soils . during the day , they seek cover in stumps , spinifex tussocks , cracks in the soil , and burrows of other animals . antechinomys laniger laniger prefers claypans in acacia woodlands , while a . l . spenceri prefers plains of granite and shrub lands .

. their nocturnal lifestyle and agility help them to avoid many predators . during the day , kultarrs stay in the nest to avoid diurnal predators . juveniles stay safe in the pouch or nest . when juveniles do leave the nest , they attach to their mother ' s back .

kultarrs utilize olfactory cues during mate selection . parents and offspring also communicate vocally . young use calls to locate their parents when they become separated . kultarrs have abnormally large eyes and ears that are adapted to their nocturnal and fossorial lifestyle .

kultarrs are relatively long lived mammals for their size . lifespan may be impacted by their ability to enter spontaneous torpor . the oldest known kultarr lived 67 months in the wild , while the oldest in captivity lived 48 months .

little is known about mating systems of kultarrs . it is suspected that olfactory cues are used in mate selection .

kultarrs are a polyoestrous mammals , and females may enter oestrus up to 6 times during the breeding season . oestrus cycles occur from july to january and may be photo - dependent . the long breeding season runs from midwinter to midsummer . breeding females have a supple pouch , elongated nipples , and long red - brown hairs . males begin spermatorrheoea in may . kultarrs have 1 to 8 offspring ( average 6 ) . gestation lasts 12 to 17 days . after birth , the young crawl into the pouch , where they remain for 30 to 48 days . weening occurs at 80 to 90 days of age in captivity . after the breeding season , the female ' s pouch regresses into a small fold . kultarrs reach sexual maturity at 11 . 5 months of age .

average age at sexual or reproductive maturity ( female ) : 11 . 5 months .

average age at sexual or reproductive maturity ( male ) : 11 . 5 months .

female kultarrs feed and protect the offspring in their pouch for 30 to 48 days . after they are weaned , young remain in the nest as the mother forages . when older , they ride on their mother ' s back as she searches for food .

listed as least concern even though it is declining ( at least in new south wales ) , because there is no indication of a large decline that would approach criterion a , and it is very widespread .

antechinomys laniger is considered a species of least concern by the iucn . it is widespread , and populations are believed to fluctuate with rain levels . the us fish & wildlife service , however , listed this species as endangered in 1970 . over - grazing by cattle and sheep as well as predation by feral cats and red foxes are major threats , and localized extinctions have occurred . changes in fire regime also negatively affect kultarrs . protection of land and animal control programs have helped conserve this species . however , additional research on food habits , home range , and movement are necessary for more specific management programs .

kultarrs appear to undergo fluctuations in population size . it is considered rare and scattered ( valente 2008 ) . this species is very difficult to trap using standard trapping techniques .

habitat degradation by sheep and cattle , and predation by cats and foxes are major threats to this species ( maxwell et al . 1996 ) . also , habitat alteration due to changes in fire regimes since european settlement ( dickman and read 1992 ) .

there is a need to develop trapping techniques to permit effective survey and monitoring of the species . other conservation measures should include implementing long - term monitoring to validate adequacy of conservation measures ; collate distribution data ; identify and determine the status of the species across its range ; construct habitat model to more accurately determine extent of source and sink habitat available to the kultarr , identify patches and allow monitoring of the changes in habitat quality , particularly due to excessive flooding and grazing . there is a need to study home range , movement , habitat and food requirements in the field if a population can be located for a 3 - 5 year population study . also , measures should include establishing adequate reserves and appropriate management inside and outside the reserve system ( maxwell et al . 1996 ) .

there are no known direct benefits of kultarrs on humans . they may affect populations of pest insects they prey upon .

in the west . the latter is now relegated to subspecific status . the species name

the kultarr usually measures 7–10 cm , with a 10–15 cm tail . it weighs 20 - 30g ; males are larger and heavier than females .

the most distinctive features are the large four - toed hind legs , enabling a hopping motion , and prominent ears . it is coloured fawn grey to sandy brown above , with a white chest and darker eye - ring .

. mating occurs in winter and spring , with young being born around august–november . the species nests in soil cracks or utilises abandoned burrows of other species .

dasyuromorphia is an order of mammals that includes most of the australasian carnivorous marsupials , including quolls , dunnarts , the numbat , the tasmanian devil , and the tasmanian wolf .

there are two extant families of dasyurmorphians , myrmecobiidae ( with one extant species , the numbat , myrmecobius fasciatus ) and dasyuridae ( with about 20 extant genera and over 70 species , including quolls , dunnarts , and the tasmanian devil ) . a third family , thylacinidae , is assumed to have gone extinct in the 20th century with the demise of the thylacine ( thylacinus cynocephalus , also known as the tasmanian wolf or tasmanian tiger ) . dasyurmorphians are found in australia , new guinea , tasmania , and some nearby islands .

some dasyurmomorphians , such as the the numbat , serve in the control of social insects , and some of the larger dasyurids , such as the tasmanian devil and various quolls , play an ecological role in eating carrion , including dead wallabies and wombats . for humans , the unique appearance of dasyuromorphians add to the beauty of nature .

while there is large size variation among extant members of dasyuromorphia , the body shape tends toward uniformity . dasyuromorphians move on four legs ( quadrupedal ) , have pointed and generally long snouts , have long tails ( dasyuromorphia means " hairy tail " ) , have four toes on the front feet and four or five toes on the hind feet , and many have a clawless toe on the hind feet . dasyuromorphians have polyprotodont dentition ( multiple lower incisor teeth as opposed to diprotodont dentition with two lower incisors ) , with four upper and three lower incisors . members of the order peramelemorphia ( the bandicoots and bilbies ) are another example of marsupials that are polyprotodont , as opposed to the diprotodont kangaroos , possums , wallabies , koala , and wombats , all of which have only two lower incisors . unlike members of peramelemorphia , the feet of dasyuromorphians tend not to have syndactylous digits ( with the second and third toes fused together while maintaining separate claws ) .

unlike herbivores , which tend to become highly specialized for particular ecological niches and diversify greatly in form , carnivores tend to be broadly similar to one another , certainly on the level of gross external form . just as northern hemisphere carnivores like cats , foxes , and weasels are much more alike in structure than , for example , camels , goats , pigs , and giraffes , so too are the marsupial predators constrained to retain general - purpose , look - alike forms—forms which mirror those of placental carnivores . the names given to them by early european settlers reflect this : the thylacine was called the tasmanian tiger , quolls were called native cats , and so on .

the primary specialization among marsupial predators is that of size : prior to the massive environmental changes that came about with the arrival of humans about 50 , 000 years ago , there were several very large carnivores , none of them members of the dasyuromorphia and all of them now extinct . those marsupial predators among the dasyuromorphians that survived into historical times ranged from the wolf - sized thylacine to the tiny long - tailed planigale , which at 4 to 6 grams is less than half the size of a mouse . most present - day dasyuromorphians , however , tend towards the lower end of the size scale , typically between about 15 or 20 grams and about 2 kilograms , or from the size of a domestic mouse to that of a small domestic cat .

to provide context , the table below also shows other major branches of the marsupial tree .

order diprotodontia ( about 137 species in 11 families , including the koala , wombats , possums , potoroos , kangaroos , wallabies and others . )

unlike most marsupials in which the females typically have an external pouch where the newborn are nursed , numbat females have no pouch . the four mammae ( milk - secreating teats ) are protected , however , by a patch of crimped , golden hair and by the swelling of the surrounding abdomen and thighs during lactation ( cooper 2011 ) .

the numbat is relatively small compared to many termite - consuming mammals , with a body length of about 17 . 5 to 27 . 5 centimeters ( 7 - 11 inches ) and a tail of about 13 . 0 to 17 centimeters ( 5 - 6 . 7 inches ) , or roughly 30 to 45 centimeters ( 12 - 17 . 7 inches ) in total length . the adult numbat weighs from about 280 to 550 grams ( 0 . 6 - 1 . 2 pounds ) ( ellis 2003 ) .

the numbat has a finely pointed muzzle , a small mouth , and small , round - tipped ears . there are five toes on the stout forefeet , and four toes on the hindfeet ; all four feet have thick and large claws ( cooper 2011 ; ellis 2003 ) . the tail is prominent and bushy . like many termite - eating animals , the numbat has an unusually long , narrow , tongue , coated with sticky saliva produced by large submandibular glands . the tongue can reach 10 centimeters from the mouth opening ( ellis 2003 ) . a further adaptation to the diet is the presence of numerous ridges along the soft palate , which apparently help to scrape termites off the tongue so that they can be swallowed .

like other mammals that eat termites or ants , the numbat has a degenerate jaw with up to 50 very small non - functional teeth , and although it is able to chew ( cooper 2011 ) , it rarely does so , because of the soft nature of its diet . uniquely among terrestrial mammals , there is an additional cheek tooth between the premolars and molars ; it is unclear whether this represents a supernumary molar tooth or a deciduous tooth retained into adult life . as a result , although not all individuals have the same dental formula , in general , it follows the unique pattern ( cooper 2011 ) :

thylacinidae is an extinct family of dasyuromorphians , whose only species to survive into modern times was the thylacine ( thylacinus cynocephalus ) , also known as the tasmanian wolf or tasmanian tiger . all other thylacinids lived in prehistoric times in australia , with specimens found in the fossil record dating back to the early miocene .

dasyuridae includes about 75 species divided into 15 genera . dasyurids are known by such common names as quolls , dunnarts , and the tasmanian devil . dasyurids are found in australia and new guinea . they inhabit a wide range of environments , including grassland , forests , and mountains , and some species are arboreal or semiaquatic .

many dasyurids are small and mouse - like , leading to the misnomer " marsupial mice , " but the group also includes the cat - sized quolls , as well as the tasmanian devil . the smallest species is the pilbara ningaui , which is from 4 . 6 to 5 . 7 cm in length , and weighs just 2–9 grams , while the largest , the tasmanian devil , is 57–65 cm long , and weighs from 6–8 kg . the smaller dasyurids typically resemble shrews or mice in appearance , with long tails and narrow , pointed noses . the larger species bear a resemblance to such placental carnivores as mongooses or mustelids ( lee 1984 ) .

many features of dasyurids are considered primitive , that is , they resemble the features of the earliest marsupials , from which other species , such as kangaroos and bandicoots , later diverged . for example , all of the toes in dasyurids are separate , whereas in many other marsupials , the second and third toes are fused . similarly , many species lack a full marsupial pouch ; instead they have a simple fold of skin surrounding the teats to provide some protection to the developing young . the dentition of dasyurids is also considered primitive , and differs from that of other marsupials , with a dental formula of : .

dasyurids are primarily insectivorous , but they will also eat small lizards , fruit , and flowers . one of the few exceptions to this rule is the tasmanian devil , which subsists mainly on vertebrate carrion ( lee 1984 ) . they have relatively simple digestive tracts , as is typical of insectivores and carnivores .

gestation lasts from 12–16 days , and results in the birth of from two to 12 young , depending on species . smaller species typically breed at least twice a year , while the larger forms tend to breed just once . the length of lactation reflects this , with young dunnarts , for example , being weaned after 60–70 days , but young quolls only after 8–9 months . most dasyurid species are sexually mature at one year of age , but , again , the quolls and tasmanian devil , being larger , take longer to mature and do not reach full adulthood for about two years ( lee 1984 ) .

after more than 2 years of preparations , the diatombase portal is now officially launched . . . .

last week - on may 30 and 31st – 8 thematic experts on talitridae came together for the first time during a lifewatch - worms sponsored workshop . the workshop took place at the hellenic centre for marine research in crete , where it was organized back - to - back with the 8th international sandy beaches symposium ( isbs ) . the group focused on identifying relevant traits for the talitridae , and adding this data through the amphipoda species database . . . .

on 23 april 2018 , a number of editors of the world register of introduced species ( wrims ) started a three day workshop in the flanders marine institute ( vliz ) . these three days were used to evaluate , complete and improve the content of this worms thematic register ( tsd ) . . . .

the 2nd worms early career researchers and 3rd worms achievement award were granted respectively to françois le coze and geoff read . congratulations ! . . .

in 2018 , to celebrate a decade of worms ' existence , it was decided to compile a list of our top marine species , both for 2017 and for the previous decade . . . .

the scleractinian corals are now accessible though their own list portal . this world list contains over 1 500 accepted names of extant species and is one of the most complete existing resources for scleractinian taxa . . .

the appearance of the multicellular animals , or metazoa , in the fossil record about 600 million years ago marks a revolution in the history of life . molecular biology is continuing to increase our understanding of metazoan evolution , yet information from fossils is still an important component in deciphering metazoan phylogeny , and data on rapidly radiating animal groups place early metazoan evolution in a new perspective .
