Dainty Green Tree Frog
The dainty green tree frog (''Ranoidea gracilenta''), also known as the graceful tree frog, is a species of tree frog in the subfamily Pelodryadinae. It is native to eastern Queensland, and north-eastern New South Wales, Australia and ranges from northern Cape York in Queensland to Gosford in New South Wales, with a small and most likely introduced population in Hornsby Heights in Sydney. It is one of two faunal emblems of the City of Brisbane. Description The dainty green tree frog is a slender, medium-sized frog, reaching a length of . It is a rich green on its dorsal surface, with a yellow ventral surface. It has a coarse, granular skin with bright orange eyes; some specimens have a light blue ring following the circumference of the eye. The posterior of the thigh is purple-brown or maroon and the tympanum is visible. In most specimens, a thin yellow or white line runs from its nostril to its eye, and this distinguishes it from the closely related red-eyed tree frog ('' L. ch ...

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 ...

City Of Brisbane
The City of Brisbane is a local government area (LGA) which comprises the inner portion of the metropolitan area of Brisbane, the capital of Queensland, Australia. Its governing body is the Brisbane City Council. Unlike LGAs in the other mainland state capitals ( Sydney, Melbourne, Perth and Adelaide), which are generally responsible only for the central business districts and inner neighbourhoods of those cities, the City of Brisbane administers a significant portion of the Brisbane metropolitan area, serving almost half of the population of the Brisbane Greater Capital City Statistical Area (GCCSA). As such, it has a larger population than any other local government area in Australia. The City of Brisbane was the first Australian LGA to reach a population of more than one million. Its population is roughly equivalent to the populations of Tasmania, the Australian Capital Territory and the Northern Territory combined. In 2016–2017, the council administered a budget of over ...

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, ...

Amphibians Of New South Wales
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 ...

Lost Frog
Lost frogs, also called translocated frogs, frogs which have been relocated, usually accidentally, outside of their original distribution. In Australia a large number of frogs (up to 10,000 a year) transported accidentally while hiding in fruit produce, flowers and building and landscape supplies. Most of the lost frogs each year are moved from Northern Australia to the larger cities in the south. The majority of the lost frogs turn up in fruit shops and markets. These frogs are often released into the surrounding areas. The release of lost frogs into areas far from their original habitat can have devastating effects on the released frog or the local frog populations. As lost frogs often end up moving from tropical to cooler areas they often cannot adapt fast enough to the new climate, and due to the stress of travelling hundreds of kilometres, often suffer injuries and are likely to die. Lost frogs are also often responsible for the spread of disease. When a frog suffering from a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange-thighed Frog
The orange-thighed frog (''Ranoidea xanthomera'') is a species of tree frog native to a small area of tropical northern Queensland, Australia. It is a green frog with distinctly orange eyes, and is very similar in appearance to the red-eyed tree frog. Description The orange-thighed frog is a medium-sized tree frog, reaching a length of . It is a slender frog, with a thin body, flat head, and large eyes, which are orange in colour. It has a green dorsal surface, with bright yellow feet and vocal sac, and a yellow band down its flank. The inner surfaces of its legs are yellow, and the outer surfaces are green. It is distinguished, physically, from the red-eyed tree frog by the presence of bright-orange thighs; the red-eyed tree frog has mauve thighs. Ecology and behaviour Male orange-thighed frogs congregate around still ponds, and call from low branches, or the edges of the water. The call is a long "aaa-rk", followed by a soft trill. They call after heavy monsoon rains. The ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Litoria Chloris
''Ranoidea chloris'', commonly known as the red-eyed tree frog or orange-eyed tree frog, is a species of tree frog native to eastern Australia; ranging from south of Sydney (Nowra area) to Proserpine in mid-northern Queensland. Description The red-eyed tree frog is a uniform bright green above, occasionally with yellow spots, and bright yellow on the underside. The front sides of the arms and legs are green, while the underside is yellow or white. The thighs may be blue/purple to blue/black in colour in adults. It has golden eyes at the centre, which change to red towards the edge of the eye. The intensity of the eye colour is variable between frogs. The tympanum is visible, and a mature frog reaches a size of 65 mm. The tadpoles are generally grey or brown, and can have gold pigment along the side. A similar species, the orange-thighed frog (''Litoria xantheroma'') is found north of Proserpine and has orange on the back of the thighs. Ecology and behaviour This spe ...

Tympanum (zoology)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Emblem
An emblem is an abstract or representational pictorial image that represents a concept, like a moral truth, or an allegory, or a person, like a king or saint. Emblems vs. symbols Although the words ''emblem'' and '' symbol'' are often used interchangeably, an emblem is a pattern that is used to represent an idea or an individual. An emblem develops in concrete, visual terms some abstraction: a deity, a tribe or nation, or a virtue or vice. An emblem may be worn or otherwise used as an identifying badge or patch. For example, in America, police officers' badges refer to their personal metal emblem whereas their woven emblems on uniforms identify members of a particular unit. A real or metal cockle shell, the emblem of St. James the Apostle, sewn onto the hat or clothes, identified a medieval pilgrim to his shrine at Santiago de Compostela. In the Middle Ages, many saints were given emblems, which served to identify them in paintings and other images: St. Catheri ...

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 ...

Fauna
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
