Roth's Tree Frog
Roth's tree frog (''Litoria rothii''), or the northern laughing tree frog, is a species of tree frog native to northern Australia and southern Papua New Guinea. Roth's tree frog is a common frog, closely related to Peron's tree frog (''Litoria peronii'') and Tyler's tree frog (''Litoria tyleri''). Description Roth's tree frog is a medium-sized frog, reaching a maximum length of . The body is elongated, with a small head and large eyes. It is an arboreal frog, and its toe pads are wider than its fingers. The dorsal surface is a dull grey to brown colour, and can be blotched with dark brown. The inner thighs and armpits are black and blotched with bright yellow or orange. The tympanum is visible, with a fold of skin covering the top portion. There are two features that distinguish it from both Peron's tree frog and Tyler's tree frog - the upper half of the iris is deep red, and it has no emerald green flecks on the dorsal surface.

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 ...

Peron's Tree Frog
Peron's tree frog (''Litoria peronii''), also known as the emerald-spotted tree frog, emerald-speckled tree frog, laughing tree frog, and maniacal cackle frog, is species of tree frog in the subfamily 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. .... It is a common frog found in Australia. Description and habitat Peron's tree frog is one of the most variably coloured frogs in Australia, with the ability to change colour in less than one hour. They don't like to be handled for long periods of time. They also vary in shades of grey and brown, where their lightest is almost white. The frog has mottled yellow and black thighs, armpits, and groin. Occasionally, emerald spots are found on the back, which increase in number with age. A characteristic uncommon in the ge ...

Tyler's Tree Frog
Tyler's tree frog or the southern laughing tree frog (''Litoria tyleri'') is an arboreal species of tree frog. It is native to eastern Australia where it occurs from south-eastern Queensland to the southern coast of New South Wales. It is generally a coastal species and is not found inland. Etymology The specific name ''tyleri'' honours Michael J. Tyler, an Australian herpetologist. Description This frog is grey-brown to fawn (of various shades) on its dorsal surface, and a whitish-yellow on its ventral surface. Females are larger than males and reach a maximum size of about 50 mm. It has green flecks on the back. The iris is golden in colour and it has cross-shaped pupils. This species is very similar to the Peron's tree frog Peron's tree frog (''Litoria peronii''), also known as the emerald-spotted tree frog, emerald-speckled tree frog, laughing tree frog, and maniacal cackle frog, is species of tree frog in the subfamily Pelodryadinae Pelodryadinae, also k ...

Wet Season
The wet season (sometimes called the Rainy season) is the time of year when most of a region's average annual rainfall occurs. It is the time of year where the majority of a country's or region's annual precipitation occurs. Generally, the season lasts at least a month. The term ''green season'' is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is or more. In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.Elisabeth M.

Metamorphosis (biology)
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis (" ametaboly"). Scientific usage of the term is technically precise, and it is not applied to general aspects of cell growth, including rapid growth spurts. Generally organisms with a larva stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation an ...

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 Western Australia
The Amphibians of Western Australia are represented by two families of frogs. Of the 78 species found, most within the southwest, 38 are unique to the state. 15 of the 30 genera of Australian frogs occur; from arid regions and coastlines to permanent wetlands. Frog species in Western Australia have not suffered the major declines of populations and diversity of many parts of the world. No species is recorded as having become extinct, despite over 50% of recent worldwide extinctions being Australian. Three species are listed as Threatened, two as Vulnerable and '' Geocrinia alba'' as Critically endangered. Threats to the species include the fungal disease Chytridiomycosis, though no infection has yet been recorded, and damage to habitat from altered land use and fire regimes. These processes have caused decline in many populations, however, some have successfully colonized newly created habitats such as dams or suburban gardens. Species such as '' Litoria moorei'' (Motorbik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of The Northern Territory
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 decli ...
