Limnodynastidae
Limnodynastidae, commonly known as the Australian ground frogs, is a family of frogs found in Australia, New Guinea, and the Aru Islands. They were formerly considered a subfamily of the Myobatrachidae, the other large radiation of terrestrial frogs in Australia, but are now considered a distinct family. Both Limnodynastidae and Myobatrachidae are thought to be the only members of the superfamily Myobatrachoidea Myobatrachoidea is a superfamily of frogs.

Platyplectrum
''Platyplectrum'' is a genus of ground-dwelling frog in the family Limnodynastidae. Species in this genus are found in Australia, New Guinea, and on the Aru Islands The Aru Islands Regency ( id, Kabupaten Kepulauan Aru) is a group of about 95 low-lying islands in the Maluku Islands of eastern Indonesia. It also forms a regency of Maluku Province, with a land area of . At the 2011 Census the Regency had a po .... They are medium-sized frogs and the dorsal skin has a sandpaper-like texture. Although this genus was described in 1863 for the species '' Platyplectrum ornatum'', in 2009 it was synonymized with the genus '' Opisthodon.'' This classification was found to be paraphyletic with respect to the former genus ''Lechriodus''. For this reason, ''Platyplectrum'' was revived in 2021 for the members of ''Opisthodon'' and ''Lechriodus''. They inhabit a range of environments from arid areas to rainforests and wet sclerophyll forests, and are active after heavy rains in summer and ...

Myobatrachoidea
Myobatrachoidea is a superfamily of frogs. It contains two families, both of which are found in Australia, New Guinea, and the Aru Islands. Some sources group these two families into a single family Myobatrachidae. Their closest relatives are thought to be the Calyptocephalellidae of southern South America, from which they diverged during the mid-Cretaceous (about 100 million years ago). Together, they comprise the clade Australobatrachia; their common ancestor is thought to have inhabited South America, with the ancestors of Myobatrachoidea dispersing to Australasia during the Cretaceous via (then ice-free) Antarctica. Both families within Myobatrachoidea are thought to have diverged from each other during the Late Cretaceous or during the earliest Paleocene (immediately after the Cretaceous-Paleogene extinction event). Taxonomy Myobatrachoidea contains the following families: * Limnodynastidae - 44 species * Myobatrachidae Myobatrachidae, commonly known as Australian gr ...

Western Spotted Frog
The western spotted frog (''Heleioporus albopunctatus'') is a species of frog in the family Limnodynastidae. It is endemic to Western Australia. Its natural habitats are temperate forests, temperate shrubland, intermittent rivers, freshwater marshes, rocky areas, granite outcrops, arable land, pastureland, open excavations, and canals and ditches. It is threatened by habitat loss and salinity. Breeding ''Heleioporus albopunctatus'' has terrestrial egg deposition. Males excavate burrows up to 1 m deep in sandy substrates surrounding ephemeral waterbodies, and commence calling in autumn (March/April). Amplexus (mating) occurs in the burrow and females deposit a clutch of eggs embedded in foam, in a chamber at the base of the burrow. Eggs develop to mid-stage tadpoles within the eggs, but final development is dependent on winter rains filling the waterbody and flooding burrows. Tadpoles then hatch and complete development in the pond. Some clutches of eggs have been found to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frogs
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the 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 dating suggests their split from other amphibians may extend further back to the Permian, 265 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 or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an ex ...

Adelotus
The tusked frog (''Adelotus brevis'') is a species of ground-dwelling frog native to eastern Australia from Eungella National Park, Queensland south to Ourimbah, New South Wales. It is the only species in the genus ''Adelotus'' - ''adelotus'' meaning "unseen" and ''brevis'' meaning "short".Martyn Robinson (2005) A Field Guide to the Frogs of Australia. Australian Museum and Reed New Holland Publication. Description The tusked frog is a unique frog within Australia, as it is the only species where the female is smaller than male. Males can reach a maximum length of about , while females reach . The common name of "tusked frog" derives from the small protrusions on the lower jaw, similar in position to tusks, which can reach about in length in males (only visible when the mouth is open). The pair of bony tusks are modified teeth that protrude from the middle of the lower jaw and fit into special grooves on the upper jaw when the mouth is closed. They are slightly curved and ...

Philoria
''Philoria'' is a genus of frogs native to eastern and southern Australia. These frogs are all confined to mountain areas, with 7 species occurring in the mountains of northern New South Wales and southern Queensland. One species occurs in Victoria. All species are listed as endangered, except the Baw Baw frog, which is listed as critically endangered. They are small to medium-sized frogs that live in water saturated sites, such as sphagnum bogs and seepages on rocky slopes. The eggs are laid in foam nests hidden from light. The tadpoles remain within the nest and live entirely on the yolk.Altig, R., & Johnston, G. (1989). Guilds of Anuran Larvae: Relationships among Developmental Modes, Morphologies, and Habitats. Herpetological Monographs, 3, 81-109. doi:10.2307/1466987 Some taxonomists class only the Baw Baw frog (''Philoria frosti'') in the genus ''Philoria'' and class the other 5 species in the genus ''Kyarranus'' because of osteological features, size differences (''Philori ...

Their common name is Australian spadefoot toads. Description Its body is very round in shape with a short neck. Its pupils are horizontal slits. It has long arms and short, stubby legs. Its fingers lack webbing and its toes may have slight to no webbing. The skin is slightly warty and very glandular. Because of its similarity to some species of toads it is often incorrectly referred to as a toad. It excretes poisonous sticky fluid from its skin when handled. It lays eggs in chains similar to some toad species. Species There are four species in this genus: References External links Amphibians of Australia Amphibian gen ...

Amphibians 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibian Families
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 ...

Heleioporus
''Heleioporus'' is a genus of frogs native to Australia. Of the six species in this genus, five live in south-west Western Australia Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to th ..., while the other one species only occurs in south-eastern Australia. All members of this genus are medium to large sized burrowing frogs with rounded heads, short bodies, bulging eyes, short limbs and the hands are free from webbing. The toes are relatively short with only a trace of fleshy webbing. A characteristic of this genus (except for ''Heleioporus eyrei'' and some ''Heleioporus psammophilus'') is the black nuptial spines that male frogs have on their first and occasionally second and third fingers. The pupil restrict to form a vertical slit and the tympanum is usually distinct. All the species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neobatrachus
''Neobatrachus'' is a genus of burrowing ground frogs native to Australia. They occur in every state except Tasmania, however this genus is absent from the far north of Australia and most of Queensland. Most of the species in this genus occur in south-western Western Australia. They are often found in arid areas and burrow underground to avoid dehydration. They are typically found in temporary claypan and flooded grassland habitats. These burrowing frogs have special genetic characteristics that help them to live in extreme environments. They stand out because some species are tetraploids instead of diploids. All species have a similar body shape, they are rounded and squat with large eyes and the pupils constrict vertically. The limbs are short and the hands are free from webbing while the feet are partially webbed. Males lack a vocal sac. Approximately 1000 eggs are laid in a chain in still water. The reproductive cycle is dependent on sufficient rainfall, an unpredictable eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
