Arthroleptis Bivittatus
''Arthroleptis bivittatus'' is a species of frog in the family Arthroleptidae. It is endemic to Guinea and only known from the holotype collected from the Tombo Island. It is uncertain whether this species is distinct from the common ''Arthroleptis poecilonotus ''Arthroleptis poecilonotus'' (common names: West African screeching frog, mottled squeaker) is a species of frog in the family Arthroleptidae. This adaptable species has a wide range within the Sub-Saharan Africa and is not considered threaten ...''. Common name Tumbo-Insel screeching frog has been coined for this species. Description The holotype, an adult female, measures in snout–vent length. The overall appearance is stocky. The tympanum is small (diameter 1.5 mm). Inter-digital webbing is absent. The long-preserved specimen is brown in colour. There are traces of a darker mid-dorsal pattern that could be similar to the hourglass pattern in ''Arthroleptis poecilonotus''.

Fritz Müller (doctor)
Friedrich "Fritz" Müller (8 May 1834 – 10 March 1895) was a Swiss doctor, zoologist, and herpetologist. He was born in Basel and studied at the University of Basel from 1852 to 1854, and then at Würzburg and Prague, where he became a medical doctor in 1857. After further experience in Vienna, Paris and Berlin, he returned to Basel to practise medicine. He was a founder member of the regional medical society in 1860 and took a leading role in the sanitary services in Basel, which he directed from 1872. He gave public lectures in zoology at the university from 1868. His zoological work focussed on reptiles, amphibians, crustaceans and arachnids. From 1873, he suffered from a chronic illness as a result of which he spent periods near the Mediterranean. He died in Basel. Eponyms In 1885 Fritz Müller described ''Rhinoplocephalus bicolor'', commonly known as "Müller's snake", and in 1889 he described ''Nessia sarasinorum'', a species of skink sometimes referred to as " ...

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] |
Arthroleptidae
The Arthroleptidae are a family of frogs found in sub-Saharan Africa. This group includes African treefrogs in the genus ''Leptopelis'' along with the terrestrial breeding squeakers '' Arthroleptis'', and several genera restricted to the Guinean forests of central and west Africa, such as the hairy frog ''(Trichobatrachus)''. Taxonomy This family is the phylogenetic sister group of reed frogs, the Hyperoliidae, which together form the lineage Laurentobatrachia, a name that commemorates work on African frogs by the Argentine herpetologist Raymond Laurent. This group is further nested within the Afrobatrachia, an ancient African endemic lineage that includes the Brevicipitidae and Hemisotidae The shovelnose frogs are the species of frogs in the genus, ''Hemisus'', the only genus in the family Hemisotidae. They are found in tropical and subtropical sub-Saharan Africa. The shovelnose frogs are moderate-sized frogs, reaching a length o .... The Arthroleptidae are separated, base ...

Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tombo Island
Tombo Island is an island in the Atlantic Ocean at the tip of the Guinean Kaloum Peninsula, approximately east of the Iles de Los, Loos Islands. The island is the site where the capital Conakry was built on. It is the site of the old city of Conakry while the new colonial city is located at Kaloum. It is linked to the peninsula by a causeway. The island was placed under a French protectorate by the king of Dubréka on 20 January 1880. This step was aimed to counter the English influence growing in the region. On 24 December 1885, the Germans renounced to be established on the Island of Tombo and obtain a territory at the border between Togo and Dahomey. The island became a French territory after its acquisition on 8 June 1889.

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Many species in this genus are small, or very small, frogs with a minimum adult size of snout-vent length. The largest species ('' Arthroleptis nikeae'' and '' Arthroleptis tanneri'') reach body lengths around . It was hypothesized that small species evolved from larger ones, but in fact the opposite seems to be case. ''Arthroleptis'' species are terrestrial leaf-litter frogs that feed on a range of terrestrial arthropods, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frogs Of Africa
The fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical realm. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife. Africa is home to many of the world's most famous fauna in human culture such as lions‚ rhinos‚ cheetahs‚ giraffes‚ antelope, hippos, leopards, zebras‚ and African elephants among many others. Origins and history of African fauna Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid-Mesozoic era. After that, four to six faunal assemblages, the so-called African Faunal Strata (AFSs) can be distinguished. The isolation of Africa was broken intermittently by discontinuous "filter routes" tha ...

Amphibians Of West Africa
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within 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 recent decades there has been a dramatic ...
