Phantasmarana
''Phantasmarana'' is a genus of frogs in the family Hylodidae. The genus is endemic to the Atlantic Forest of southeastern Brazil. Members of this genus are associated with fast-flowing rivers. They are difficult to collect because they are easily disturbed and plunge into the torrential waters. Their teeth of are fanglike and larger than those of their close relatives. This might be associated with their predatory habits: at least two species are known prey on small vertebrates as well as invertebrates. The tadpoles are aquatic. ''Phantasmarana'' are relatively large frogs, with adults attaining lengths up to in snout–vent length. The genus name, ''Phantasmarana'' (literally translating to "phantom frog"), refers to the extreme rarity of wild members of this genus, as well as the lack of an advertisement call from members of the genus, instead making enigmatic noises. Members of ''Phantasmarana'' were formerly placed in '' Megaelosia'', which is now thought to contain only on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megaelosia
''Megaelosia goeldii'', also known as the Rio big-tooth frog, is a species of frog in the family Hylodidae. It is the only member of the genus ''Megaelosia.'' It is endemic to Southeast Brazil and occurs in São Paulo and Rio de Janeiro states. It is named after Émil Goeldi, a Swiss zoologist who worked in Brazil. Taxonomy The genus ''Megaelosia'' formerly contained several other species, but all of these were reclassified in a new genus, ''Phantasmarana'', in 2021 based on a phylogenetic study, leaving ''M. goeldii'' as the only remaining member of ''Megaelosia''. Description Males measure and females in snout–vent length (based on 2 males and 3 females only). The dorsolateral skin is granular. The snout is subacuminate in dorsal view and protruding in profile. The canthus rostralis is evident and straight. Males have neither vocal sacs nor vocal slits. Diet Stomach contents have been found to contain insects (cockroaches, Coleoptera, lepidopteran caterpillars), earthwor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hylodes
''Hylodes'' is a genus of frogs in the family Hylodidae. It might be paraphyletic with respect to '' Megaelosia''. The genus is endemic to southeastern Brazil. They are also known as the tree toads, or more ambiguously, as torrent frogs. They are diurnal and usually inhabit shallow mountain streams. Species The following species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.

Hylodes Meridionalis
''Hylodes meridionalis'' is a species of frog in the family Hylodidae. It is endemic to Brazil. Its natural habitats are subtropical or tropical moist lowland forest and rivers. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species.

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), 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, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, 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 (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Günther
Albert Karl Ludwig Gotthilf Günther FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook of zoology for students of ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world.

Alsodidae
The Alsodidae are a small family of frogs from South America between Patagonia and southern Brazil. It contains 30 species in three genera. This family, along with several other families, used to be included in the family Leptodactylidae. It was then a subfamily in the family Cycloramphidae, before being recognized as a family first in 2011. Genera The family contains three genera: *'' Alsodes'' Bell, 1843 (19 species) *'' Eupsophus'' Fitzinger, 1843 (10 species) *'' Limnomedusa'' Fitzinger, 1843 (1 species) However, the placement of ''Limnomedusa'' is highly uncertain, and it might belong to the family Cycloramphidae. In contrast, '' Alsodes''+'' Eupsophus'' group (''sensu stricto'', after moving some species formerly included in the latter genus to other genera) forms a well-supported, monophyletic group. These genera are Patagonian endemics and represent the largest part of the amphibian diversity in that area. ''Eupsophus'' species are restricted to forested areas at southern ...
