Fejervarya
''Fejervarya'' is a genera of frogs in the family Dicroglossidae found in Asia. First proposed in 1915 by István József Bolkay, a Hungarian naturalist, the genus did not see widespread adoption at first. As late as the 1990s it was generally included in ''Rana'', but more recent studies have confirmed its distinctness. These frogs are remarkable for being extremely euryhaline by amphibian standards. Species such as the crab-eating frog (''F. cancrivora'') can thrive in brackish water, and its tadpoles can even survive in pure seawater. Systematics and taxonomy ''Fejervarya'' was first introduced as subgenus of ''Rana'' and later placed as subgenus as ''Limnonectes''. It was treated as an independent genus first in 1998. However, ''Fejervarya'' sensu lato was found to be paraphyletic with respect to '' Sphaerotheca''. This issue was eventually resolved in 2011 by splitting some species to the genus '' Zakerana'' (renamed in 2021 as '' Minervarya''). ''Fejervarya'', as now ...

Crab-eating Frog
The crab-eating frog (''Fejervarya cancrivora'') is a frog native to south-eastern Asia including Taiwan, China, the Philippines and more rarely as far west as Orissa in India. It has also been introduced to Guam, and was most likely introduced from Taiwan. It inhabits mangrove swamps and marshes and is one of only 144 known modern amphibians which can tolerate brief excursions into seawater. This frog can tolerate marine environments (immersion in sea water for brief periods or brackish water for extended periods) by increasing urea production and retention, and by remaining slightly hyperosmotic within urea and sodium flux. Adults can survive in salt water with salinity as high as 2.8%, and tadpoles can survive salinities as high as 3.9%. Diet The food sources of the crab-eating frog are mainly determined by the locally available prey. Near fresh water, its diet consists largely of insects. But in an environment with brackish water, small crustaceans, including crab Crabs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fejervarya Limnocharis
''Fejervarya limnocharis'' is a species of frog found in South East Asia and parts of Indochina. It is known under many common names, including Boie's wart frog, rice field frog, and Asian grass frog. Molecular studies of the species complex (after Boulenger) suggest that there may be multiple species involved. Description Snout pointed, projecting beyond mouth. Canthus obtuse, loreal oblique, more or less concave. Internarial space is longer than interorbital width, which is much less than width of the upper eyelid. Tympanum distinct, half to twothirds the diameter of eye. Fingers obtusely pointed, first longer than second, subarticular tubercles very prominent. Tibiotarsal articulation reaches tympanum or naris. Toes obtuse or with slightly swollen tips, half webbed, subarticular tubercles small and prominent. Body with small tubercles, sometimes small longitudinal folds are present, ventrum smooth except belly and thighs which are granular posteriorly. Male with loose gular reg ...

Minervarya
''Minervarya'' is a genus of frogs in the family Dicroglossidae from south Asia (Sri Lanka, the Indian subcontinent including Pakistan, Nepal, and Bangladesh), and Nepal and Bhutan.

''Sphaerotheca'' is a genus of true frogs. They can be found in South Asia.

Dicroglossidae
The frog family Dicroglossidae occurs in tropical and subtropical regions of Asia and Africa, with most genera and species being found in Asia. The common name of the family is fork-tongued frogs. The Dicroglossidae were previously considered to be a subfamily in the family Ranidae, but their position as a family is now well established. Subfamilies and genera The two subfamilies contain 213 species in 13–15 genera, depending on the source. Dicroglossinae Anderson, 1871 — 197 species in 12 genera: Occidozyginae Fei, Ye, and Huang, 1990 — 16 species in two genera: *''Ingerana'' Dubois, 1987 (four species) *''Occidozyga'' Kuhl and Van Hasselt, 1822 (12 species) Phylogeny The following phylogeny of Dicroglossidae is from Pyron & Wiens (2011).

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific grav ...
