Antechinus
''Antechinus'' (// ('ant-echinus')) is a genus of small dasyurid marsupial endemic to Australia. They resemble mice with the bristly fur of shrews. Names They are also sometimes called 'broad-footed marsupial mice', 'pouched mice', or 'Antechinus shrews'. However, the majority of those common names are considered either regional or archaic; the modern common name for the animal is antechinus. Description ''Antechinus'' have short fur and are generally greyish or brownish in colour, varying with species. The fur is dense and generally soft. Their tails are thin and tapering and range from slightly shorter to slightly longer than body length. Their heads are conical in shape and ears are small to medium in size. Some species have a relatively long, narrow snout that gives them a shrew-like appearance. Species vary from in length and weigh when fully grown. '' A. agilis'' is the smallest known species, and '' A. swainsonii'' the largest. Sexual dimorphism occurs in most species ...

Tropical Antechinus
The tropical antechinus (''Antechinus adustus''), also known as the rusty antechinus, is a species of small marsupial carnivore, particularly closely related to the brown antechinus (''Antechinus stuartii''). It is found in a small area of tropical vine forest from Paluma (near Townsville) to Mount Spurgeon (near Mossman) in northeastern Queensland, Australia. It differs from the brown antechinus, with which it was previously thought to be conspecific Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organism ..., in its longer and darker fur. It shares the unusual mating behaviour of many of its relatives in that shortly after the breeding season all males die from stress-related disease.

Yellow-footed Antechinus (Antechinus Flavipes) (17067818099)
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 its immune system becomes compromised, resulting in stress–related death before it is one year old. Taxonomy The yellow-footed antechinus was described in 1838 by George Robert Waterhouse, referring to a specimen that was collected north of the Hunter River in New South Wales. The author tentatively placed the new species with the genus ''Phascogale'', based on similar dentition by reference to a description but without a skull for a closer comparison. The specific epithet ''flavipes'' means “yellow-footed.” The species has occasionally been combined with the '' Antechinus stuartii'' (brown antechinus). A member of the family Dasyuridae, the yellow-footed antechinus is the most widespread of all the members of its genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver-headed Antechinus
The silver-headed antechinus (''Antechinus argentus'') is a species of dasyurid marsupial of the genus Antechinus. Described in 2013, the species is known only from three locations so far: Blackdown Tableland National Park, Kroombit Tops National Park and Bulburin National Park in central Queensland. It is one of the most recently described Australian marsupial Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a r ...s.

Antechinus Stuartii
The brown antechinus (''Antechinus stuartii''), also known as Stuart's antechinus and Macleay's marsupial mouse, is a species of small carnivorous marsupial of the family Dasyuridae. The males die after their first breeding season, and the species holds the world record for being the world's smallest semelparous mammal. Description ''Antechinus stuartii'' is mostly light brown above, including the upper surfaces of its feet, and a lighter brown below and on its tail. Its body length is and its tail , and it weighs . Unlike in other members of ''Antechinus'', no pale-coloured eye ring occurs. '' Antechinus agilis'' is similar in appearance and difficult to distinguish except by its distribution. Taxonomy The brown antechinus was only the third in its genus to be described and as such, until recently, has included species such as the agile antechinus (''Antechinus agilis''), the subtropical antechinus (''Antechinus subtropicus''), and the tropical antechinus (''Antechinus adustus ...

Fawn Antechinus
The fawn antechinus (''Antechinus bellus'') is a species of small carnivorous marsupial found in northern Australia. It is the only ''Antechinus'' to be found in the Northern Territory and has a patchy, restricted range. Taxonomy The earliest scientific collection of a fawn antechinus was made by John T. Tunney, and the first zoological description was made in 1904 by the renowned biologist Oldfield Thomas, who gave it the species name ''bellus'', meaning beautiful. It has never been confused with other species. It is a member of the family Dasyuridae and of the genus ''Antechinus'' (meaning "hedgehog-equivalent"), which has nine other members. Description The fawn antechinus is unique among antechinuses, being considerably paler than many of its relatives. It is a light grey colour and is distinguished from the only other similar species in the area where it lives (the sandstone dibbler and the red-cheeked dunnart) by its larger size and paler colouring. It is insectivorous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dusky Antechinus
The dusky antechinus (''Antechinus swainsonii''), also known as Swainson's antechinus or the dusky marsupial mouse, is a species of small marsupial carnivore, a member of the family Dasyuridae. It is found in Australia. Taxonomy The dusky antechinus was described by English naturalist George Robert Waterhouse in 1840, the second antechinus to be described. It was named in honour of the zoologist and artist William Swainson, with the holotype likely being a specimen collected by Swainson's correspondent Thomas Lempriere from the Tasman Peninsula in Tasmania. There are three subspecies: *''A. s. swainsonii'', found in Tasmania; *''A. s. insulanus'', found in the Grampians National Park, Victoria; *''A. s. mimetes'', found from south-eastern Queensland through eastern New South Wales to south-western Victoria. Description The dusky antechinus is the largest antechinus. The largest and darkest fur Dusky Antechinus occur in higher altitudes. It can be distinguished from its relativ ...

Sexual Dimorphism
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrews
Shrews (family Soricidae) are small mole-like mammals classified in the order Eulipotyphla. True shrews are not to be confused with treeshrews, otter shrews, elephant shrews, West Indies shrews, or marsupial shrews, which belong to different families or orders. Although its external appearance is generally that of a long-nosed mouse, a shrew is not a rodent, as mice are. It is, in fact, a much closer relative of hedgehogs and moles; shrews are related to rodents only in that both belong to the Boreoeutheria magnorder. Shrews have sharp, spike-like teeth, whereas rodents have gnawing front incisor teeth. Shrews are distributed almost worldwide. Among the major tropical and temperate land masses, only New Guinea, Australia, New Zealand, and South America have no native shrews. However, as a result of the Great American Interchange, South America does have a relatively recently naturalised population, present only in the northern Andes. The shrew family has 385 known s ...
