Petropedetidae
The Petropedetidae are a family of frogs containing three genera and 12 species. They are found in sub-Saharan tropical Africa and are sometimes known under common name African torrent frogs. They are inhabitants of the splash-water zone of clear-running streams predominantly in forests. Tadpoles are either semiterrestrial in the spray zone or fully aquatic in zones of the strongest currents. Some species guard their clutches. They are small ('' Ericabatrachus'') or medium- to large-sized frogs ('' Arthroleptides'' and '' Petropedetes''). Taxonomy The Petropedetidae are related to true frogs, family Ranidae, and have often been considered as a subfamily within a broadly defined Ranidae. However, they are now commonly treated as a family, although the genera included may differ between sources. In particular, ''Conraua ''Conraua'', known as slippery frogs or giant frogs is a genus of large frogs from sub-Saharan Africa. ''Conraua'' is the only genus in the family Conrauidae. A ...

Arthroleptides
''Arthroleptides'' is a small genus of frogs in the family Petropedetidae. Their common name is rocky river frogs. They are found in the mountains of East Africa (Tanzania, Kenya, and probably Uganda). They have been considered to belong to '' Petropedetes'', which after exclusion of ''Arthroleptides'' is restricted to Central Africa. ''Arthroleptides'' species have distinct tympana and no external vocal sacs. Males have femoral glands, and in the breeding state, spiny nuptial excrescences. Tadpoles live on wet rocks out of water. Species The three species are: * '' Arthroleptides dutoiti'' Loveridge, 1935 * '' Arthroleptides martiensseni'' Nieden, 1911 "1910" * '' Arthroleptides yakusini'' Channing, Moyer, and Howell, 2002 Also, one undescribed species from the Nguru Mountains The Nguru Mountains are a mountain range in Morogoro Region, Tanzania, Africa. The Nguru Mountains are part of the Eastern Arc Mountains. The mountains are predominantly covered with rainforest, home t ...

Ericabatrachus
''Ericabatrachus'' is a genus of frogs in the family Petropedetidae endemic to the Bale Mountains in Ethiopia. It is monotypic, being represented by the single species ''Ericabatrachus baleensis'', commonly known as the Bale Mountains frog. Taxonomy ''Ericabatrachus baleensis'' is monotypic within its genus. The phylogenetic relationships of this poorly known species have been debated, but molecular analyses place it the family Petropedetidae, instead of Phrynobatrachidae or Pyxicephalidae, where it has also been placed. Its sister taxon is '' Petropedetes''. Description Bale Mountains frogs are small; adult males measure in snout–vent length and females . Their fingers are not webbed and toes have rudimentary webbing. Adult males have well-defined femoral glands. Habitat and conservation Its natural habitats are grassy banks of small, fast-flowing streams in giant heath woodland and adjoining ''Schefflera''-''Hagenia'' forest. It is critically endangered because its range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petropedetes Cameronensis
''Petropedetes cameronensis'', sometimes known as the Cameroon water frog, is a species of frog in the family Petropedetidae. It is found in southeastern Nigeria, southwestern Cameroon, and on the island of Bioko (Equatorial Guinea). It is the type species of the genus ''Petropedetes''. Description ''Petropedetes cameronensis'' is a small-sized ''Petropedetes'' with compact body. Males measure and females in snout–vent length. The snout is short. The tympanum is very small and rather indistinct, and without tympanic papilla (present in breeding males of many other ''Petropedetes'' species). The iris is golden. The canthus rostralis is sharp. The dorsum is light or dark brown with pale spots. Dorsal skin structure is variable with larger warts on the flanks and few large, longitudinal warts on back. The toes are approximately half-webbed. The male advertisement call is a whistle or a trill that drowns the noise of flowing water. The tadpole has a muscular tail that enables ...

Petropedetes
''Petropedetes'' is a genus of frogs in the family Petropedetidae. In 2002, the genus absorbed all three species of the genus ''Arthroleptides'', but they were moved back in 2014. The informally assigned common name for frogs in this genus (and for frogs in certain other genera) is torrent frogs. The following species are recognised in the genus ''Petropedetes'': * ''Petropedetes cameronensis'' (Reichenow, 1874) * ''Petropedetes euskircheni'' (Barej et al., 2010) * ''Petropedetes johnstoni'' (Boulenger, 1888) * ''Petropedetes juliawurstnerae'' (Barej et al., 2010) * ''Petropedetes newtonii'' (Bocage, 1895) – Barej et al. (2010) considers ''P. darwinii'' occurring in Bioko Island (Equatorial Guinea) a synonym of ''P. johnstoni''. * ''Petropedetes palmipes'' Boulenger, 1905 * ''Petropedetes parkeri'' (Amiet, 1983) * ''Petropedetes perreti'' (Amiet, 1973) * ''Petropedetes vulpiae ''Petropedetes'' is a genus of frogs in the family Petropedetidae.

True Frog
True frogs is the common name for the frog family Ranidae. They have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa (including Madagascar), and Asia. The Asian range extends across the East Indies to New Guinea and a single species (the Australian wood frog (''Hylarana daemelii'')) has spread into the far north of Australia. Typically, true frogs are smooth and moist-skinned, with large, powerful legs and extensively webbed feet. The true frogs vary greatly in size, ranging from small—such as the wood frog (''Lithobates sylvatica'')—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole stage. However, as in most families of frogs, there is large variation of habitat within the family. There are also arboreal speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Conraua
''Conraua'', known as slippery frogs or giant frogs is a genus of large frogs from sub-Saharan Africa. ''Conraua'' is the only genus in the family Conrauidae. Alternatively, it may be placed in the family Petropedetidae. This genus includes the largest frog of the world, '' Conraua goliath'', which may grow to in snout–vent length and weigh as much as . Four of the seven species in this genus are threatened. Etymology The generic name ''Conraua'' honours Gustav Conrau, a German trader and labour recruiter in Cameroon who was the collector of the holotype of '' Conraua robusta'', the type species of the genus. Species The recognized species are: *''Conraua alleni'' *'' Conraua beccarii'' *'' Conraua crassipes'' *''Conraua derooi'' Hulselmans, 1972 *'' Conraua goliath'' (Boulenger, 1906) – goliath frog *'' Conraua robusta'' Nieden, 1908 – Cameroon slippery frog *'' Conraua sagyimase'' Neira-Salamea, Ofori-Boateng, Kouamé, Blackburn, Segniagbeto, Hillers, Barej, ...

Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum of Berlin from 1874 to 1921. He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing ''Die Vögel Afrikas'' (1900–05). He was also an expert on parrots, describing all species then known in his book ''Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien'' (illustrated by Gustav Mützel, 1839–1893). He also wrote ''Die Vögel der Bismarckinseln'' (1899). He was editor of the ''Journal für Ornithologie'' from 1894 to 1921. A number of birds are named after him, including Reichenow's woodpecker and Reichenow's firefinch. His son Eduard Reichenow was a famous protozoologist. Reichenow is known for his classification of birds into six groups, described as "shortwings, swimmers, stiltbirds, skinb ...

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 ...

Sub-Saharan
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead grouped with the definition of MENA (i.e. Middle East–North Africa) as it is part of the ...
