Fejervarya Cancrivora
''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 defi ...

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 ...

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ...

Cryptic Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties Variety may refer to: Arts and entertainment Entertainment formats * Variety ( ...
