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), earthw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Hylodidae
Hylodidae, commonly known as giant Neotropical torrent frogs, is a Family (biology), family of frogs native to Brazil and northern Argentina. Phylogenetic evidence suggests the Hylodidae being the sister group to the Alsodidae. ''Megaelosia, Megaelosia goeldii'' is one species that lost the ability to produce vocalizations which in turn is denoted as mute. Through observation of aggressive interactions, it was found that the species' vocal sacs are used for one form of its visual signaling and communication. Diversity The family contains 48 species in four genera: * ''Crossodactylus'' André Marie Constant Duméril, A.M.C. Duméril & Gabriel Bibron, Bibron, 1841 (13 species) * ''Hylodes'' Leopold Fitzinger, Fitzinger, 1826 (26 species) * ''Megaelosia'' AlÃpio de Miranda-Ribeiro, Miranda-Ribeiro, 1923 (one species) * ''Phantasmarana'' Vittorazzi, Augusto-Alves, Neves-da-Silva, species:Ana Maria Paulino Telles de Carvalho e Silva, Carvalho-e-Silva, species:Shirlei Maria Recco-Pi ...

Émil Goeldi
Émil August Goeldi (var. Göldi, Portuguese var. EmÃlio Augusto Goeldi) (28 August 1859 – 5 July 1917 in Bern), was a Swiss-Brazilian naturalist and zoologist. He was the father of Oswaldo Goeldi, a noted Brazilian engraver and illustrator. Biography Goeldi studied zoology in Jena, Germany with Ernst Haeckel, and in 1884 he was invited by Ladislau de Souza Mello Netto, the influential director of the Brazilian Museu Imperial e Nacional, to work at that institution. Goeldi arrived in Rio de Janeiro in 1885 to work in the National Museum (now the Museu Nacional do Rio de Janeiro. In May 1890, he was fired, due to political circumstances related to the proclamation of the republic and the exile of his principal benefactor, Emperor D. Pedro II. He was then invited by the governor of the state of Pará, Lauro Sodré, to reorganize the Pará Museum of Natural History and Ethnography, in Belém, which had been founded in 1866 by Domingos Soares Ferreira Penna.

AlÃpio De Miranda-Ribeiro
AlÃpio de Miranda-Ribeiro (21 February 1874, Rio Preto, Minas Gerais – 8 January 1939) was a Brazilian herpetologist and ichthyologist. His son, Paulo de Miranda-Ribeiro (1901–1965), was also a zoologist. From an early age AlÃpio de Miranda-Ribeiro had a passion for natural history; as an adolescent he translated works of Buffon into Portuguese. He studied medicine in Rio de Janeiro, and from 1894 worked as a preparator at the National Museum of Brazil. Here he later served as secretary (from 1899), and director of the department of zoology (from 1929). During his career he explored the Amazon region many times, and under the direction of Candido Rondon (1865–1958) he took part in installing the first telegraph through the Amazon and Mato Grosso. In 1911, after visiting museums and fishery programs in Europe and the United States, he founded a fisheries inspectorate in Brazil, the first official services on fisheries in the nation. In 1911 he published the highly re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tadpole
A tadpole or polliwog (also spelled pollywog) is the Larva, larval stage in the biological life cycle of an amphibian. Most tadpoles are fully Aquatic animal, aquatic, though some species of amphibians have tadpoles that are terrestrial animal, terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians, such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology (biology), morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fos ...
