Cooloola Tree Frog
The Cooloola sedge frog or Cooloola tree frog (''Litoria cooloolensis'') is a species of frog in the subfamily Pelodryadinae. It is endemic to Australia and only known from Fraser and North Stradbroke Islands, off south-eastern Queensland. Habitat It inhabits sandy coastal and island freshwater lakes and wallum creeks, with a preference for dense reed beds. It is threatened by water extraction and pollution and by tramping of the reef beds. It occurs in the Great Sandy National Park. Description This amphibian's back is yellowish green, speckled with dark spots, and the hidden surfaces of its thighs are orange with a purple-brown stripe. The belly is grainy and white in color. ''L. cooloolensis'', like other members of the genus Litoria, has horizontal irises. Taxonomy ''Litoria'' ''cooloolensis'' is part of the species-group ''L. bicolor'', which was created to accommodate 7 species from the region that had characteristics in common.

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Litoria Bibonius
''Litoria bibonius'' is a species of frog of the subfamily Pelodryadinae. Distribution This species is found in the D'Entrecasteaux, Normanby and Goodenough islands in Papua New Guinea. Description It can be distinguished from other lowland New Guinea green tree frogs by the following features: only one third of its fingers are webbed, it has no vomerine teeth, it has a smooth tympanium instead of a granular one, and its snout is long and pointed. The hidden surfaces of its thighs are yellow and its dorsum is uniformly green. Like other members of the Litoria genus, it has horizontal irises, but unlike all Litoria species from Papua New Guinea, it has red eyes. Taxonomy ''Litoria'' ''bibonius'' is part of the species-group ''L. bicolor'', which was created to accommodate 7 species from the region that had characteristics in common. The other members of the group are: ''Litoria cooloolensis'' and ''Litoria fallax'' in Australia; ''Litoria bicolor The northern dwarf t ...

Amphibians Of Queensland
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Endemic Fauna Of Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frogs Of Australia
Amphibians of Australia are limited to members of the order Anura, commonly known as frogs. All Australian frogs are in the suborder Neobatrachia, also known as the modern frogs, which make up the largest proportion of extant frog species. About 230 of the 5,280 species of frog are native to Australia with 93% of them endemic. Compared with other continents, species diversity is low, and may be related to the climate of most of the Australian continent. There are two known invasive amphibians, the cane toad and the smooth newt. Origins The Australian continent once formed part of the supercontinent Pangaea, which split into Gondwana and Laurasia approximately 180 million years ago. The earliest true frog fossil, ''Vieraella herbsti'', is dated between 188 and 213 million years old. This predates the splitting of Gondwana, and has resulted in frogs present on all continents. The first two continents to split from Australia were South America and Africa. The amphibian fauna of b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Litoria
''Litoria'' is a genus of hylid tree frogs, sometimes collectively referred to as Australasian treefrogs, that are native to Australia, the Bismarck Archipelago, the Solomon Islands, New Guinea, the Lesser Sunda Islands, and the Moluccan Islands. They are distinguishable from other tree frogs by the presence of horizontal irises, no pigmentation of the eyelids, and their distribution east and south from Wallacea. Over one hundred species are recognised and new species are still being added, such as the Pinocchio frog discovered in 2008 and described in 2019. The species within the genus ''Litoria'' are extremely variable in appearance, behaviour, and habitat. The smallest species is the javelin frog (''L. microbelos''), reaching a maximum snout–to– vent length of , while the largest, the giant tree frog (''L. infrafrenata''), reaches a size of . The appearance, behaviour, and habitat of each frog is usually linked. The small, darkly coloured frogs are generally terrestrial, ...

Litoria Bicolor
The northern dwarf tree frog (''Litoria bicolor'') is a small species of tree frog native to northern Australia, from the Kimberly region of Western Australia to Bowen, Queensland, and Aru Islands of Indonesia. These small frogs are also commonly called sedge frogs. The population occurring in Indonesia may not be ''L. bicolor'', and research on call structure or genetics is needed to confirm its taxonomic status. Description Litoria bicolor The northern dwarf tree frog is small, slender tree frog growing up to 30 mm in length. It has a green dorsal surface and a thin bronze dorsolateral band that begins at the eye.Barker, J., Grigg, G. C., and Tyler, M. J. (1995). ''A Field Guide to Australian Frogs.'' Surrey Beatty and Sons, New South Wales. There is often a central bronze band running along the spine of the back. A narrow white stripe runs from under the eye, at the corner of the mouth, to the base of the arm. The ventral surface is cream or yellowish, with golden ...

Pelodryadinae
Pelodryadinae, also known as Australian treefrogs (although not all members are arboreal), is a subfamily of frogs found in the region of Australia and New Guinea, and have also been introduced to New Caledonia, Guam, New Zealand, and Vanuatu. The subfamily is thought to be the sister group to the leaf frogs (Phyllomedusinae), a subfamily of arboreal frogs known from the Neotropics. The common ancestor of both subfamilies is thought to have lived in early Cenozoic South America, with the two subfamilies diverging from one another during the Eocene. The ancestors of the subfamily Pelodryadinae likely invaded Australasia via Antarctica, which at the time was not yet frozen over, thus was hospitable for the dispersing frogs. The clade comprising both subfamilies is sister to the Hylinae, from which they diverged in the early Paleogene. Classification The subfamily contains 222 species in three genera: * ''Litoria'' (102 species) * ''Nyctimystes'' (44 species) * ''Ranoidea'' (71 sp ...

Litoria Fallax
The eastern dwarf tree frog (''Litoria fallax''), also known as the eastern sedge-frog, is a species of tree frog. It is a small and very common frog and found on the eastern coast of Australia, from around Cairns, Queensland, to around Ulladulla, New South Wales. Individual frogs of this species are often found elsewhere, having been accidentally relocated by transported fruit boxes. Confirmed sightings of breeding pairs have confirmed their survival in Victoria's cooler climate. Description This is a small species of frog; females can reach a maximum size of 25–30 mm, while males may only reach 20 mm when fully grown. It is of variable colour (depending upon temperature and colour of surrounding environment), ranging from fawn to light green on top, and occasionally has black flecks on its back. A white line begins under the eye, and joins the white stomach. A brown line begins from the nostril, and continues across the eye, and between the green (or fawn) and whi ...
