Waterfall Frog
The Australian waterfall frog or torrent treefrog (''Ranoidea nannotis'') is a species of tree frog native to Far North Queensland, Australia. The common name "waterfall frog" is indicative of its habitat of moist, rocky streams, and is often found along waterfalls within its range. Taxonomy The waterfall frog is one of the four species of Australian torrent treefrogs that comprise the '' Ranoidea nannotis'' species group. The other species are the mountain mist frog, common mist frog, and the armoured mist frog. Description The waterfall frog is large in size, reaching 5.5 cm in length. The dorsal surface is mottled with puck brown. The patterning on the back is similar to its habitat, allowing for effective camouflage against granite. The ventral surface is bright orange, green, and pink in colour, and granular. The posterior ventral surface is translucent, showing internal parts. The toe pads of ''R. nannotis'' are very large in comparison to toe width, to aid in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Frog
A tree frog (or treefrog) is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state. Several lineages of frogs among the Neobatrachia have given rise to treefrogs, although they are not closely related to each other. Millions of years of convergent evolution have resulted in very similar morphology even in species that are not very closely related. Furthermore, tree frogs in seasonally arid environments have adapted an extra-epidermal layer of lipid and mucus as an evolutionary convergent response to accommodate the periodic dehydration stress. Description As the name implies, these frogs are typically found in trees or other high-growing vegetation. They do not normally descend to the ground, except to mate and spawn, though some build foam nests on leaves and rarely leave the trees at all as adults. Tree frogs are usually tiny as their weight has to be carried by the branches and twigs in their habitats. While some reach 10 ...

Litoria Wilcoxi
''Ranoidea wilcoxii'', also known as the stony-creek frog, eastern stony creek frog, and Wilcox's frog, is a species of frog in the subfamily Pelodryadinae. It is endemic to Australia, being found solely on the eastern coast between Ingham, QLD, and Sydney, NSW, and as far west as Atherton, QLD. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, rivers, intermittent rivers, and pastureland. Taxonomy This species is almost identical physiologically to Lesueur's frog, and is identical physiologically to '' R. jungguy''. It can be distinguished from Lesueur's frog by the presence of blue spots on the thigh, which are missing in ''R. wilcoxii''. Geographical distribution and genetic testing are the only methods of differentiating ''R. wilcoxii'' from ''R. jungguy''. Description ''Ranoidea wilcoxii'' shows extreme sexual dimorphism, meaning the males and females have different appearances. Females can reach a length of up t ...

Nature Conservation Act Endangered Biota
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

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 ...

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, ...

Endangered Fauna Of Australia
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chytridiomycosis
Chytridiomycosis ( ) is an infectious disease in amphibians, caused by the chytrid fungi ''Batrachochytrium dendrobatidis'' and ''Batrachochytrium salamandrivorans''. Chytridiomycosis has been linked to dramatic population declines or extinctions of amphibian species in western North America, Central America, South America, eastern Australia, east Africa (Tanzania), and Dominica and Montserrat in the Caribbean. Much of the New World is also at risk of the disease arriving within the coming years. The fungus is capable of causing sporadic deaths in some amphibian populations and 100% mortality in others. No effective measure is known for control of the disease in wild populations. Various clinical signs are seen by individuals affected by the disease. A number of options are possible for controlling this disease-causing fungus, though none has proved to be feasible on a large scale. The disease has been proposed as a contributing factor to a global decline in amphibian populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vocal Sac
The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example; The vocal sac is open to the mouth cavity of the frog, with two slits on either side of the tongue. To call, the frog inflates its lungs and shuts its nose and mouth. Air is then expelled from the lungs, through the larynx, and into the vocal sac. The vibrations of the larynx emits a sound, which resonates on the elastic membrane of the vocal sac. The resonance causes the sound to be amplified and allows the call to carry further. Muscles within the body wall force the air back and forth between the lungs and vocal sac. Development The development of the vocal sac is different in most species, however they mostly follow the same process. The d ...
