Cambondo Screeching Frog
''Arthroleptis carquejai'' is a species of frog in the family Arthroleptidae. It is known with certainty only from north-western Angola, but there is also a recent record from Gabon. If this is correct, its distribution might also include intervening areas in the Republic of the Congo and the Democratic Republic of the Congo. The specific name ''carquejai'' honours , Portuguese professor, journalist, and philanthropist. The common names Cambondo screeching frog and Carqueja's squeaker have been proposed for it. Description The holotype is a female measuring in snout–vent length. The holotype has gular and anterior venter areas that are darkly pigmented with pale spots, distinguishing this species from otherwise quite similar ''Arthroleptis variabilis ''Arthroleptis variabilis'' is a species of frog in the family Arthroleptidae. It is found in the lowlands of eastern Nigeria, Cameroon, Equatorial Guinea (including the island of Bioko), Gabon, the Central African Republi ...

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 The hairy frog (''Trichobatrachus robustus'') also known as the horror frog or Wolverine frog, is a Central African species of frog in the family Arthroleptidae. It is monotypic within the genus ''Trichobatrachus''. Its common name refers to the ... ''(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 Arthroleptidae are separated ...

Gabon
Gabon (; ; snq, Ngabu), officially the Gabonese Republic (french: République gabonaise), is a country on the west coast of Central Africa. Located on the equator, it is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly and its population is estimated at million people. There are coastal plains, mountains (the Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Since its independence from France in 1960, the sovereign state of Gabon has had three presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more transparent electoral process and reformed some governmental institutions. With petroleum and foreign private investment, it has the fourth highest HDI in the region (after Mauritius, Seychelles and South Africa) and the fifth highest GDP per capita (PPP) i ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

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] |
Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gular Skin
Gular skin (throat skin), in ornithology, is an area of featherless skin on birds that joins the lower mandible of the beak (or ''bill'') to the bird's neck. Other vertebrate taxa may have a comparable anatomical structure that is referred to as either a gular sac, throat sac, vocal sac or gular fold. In birds Gular skin can be very prominent, for example in members of the order Phalacrocoraciformes as well as in pelicans (which likely share a common ancestor). In many species, the gular skin forms a flap, or gular pouch, which is generally used to store fish and other prey while hunting. In cormorants, the gular skin is often colored, contrasting with the otherwise plain black or black-and-white appearance of the bird. This presumably serves some function in social signalling, since the colors become more pronounced in breeding adults. In frigatebirds, the gular skin (or gular sac or throat sac) is used dramatically. During courtship display, the male forces air into the sac, ...

Arthroleptis Variabilis
''Arthroleptis variabilis'' is a species of frog in the family Arthroleptidae. It is found in the lowlands of eastern Nigeria, Cameroon, Equatorial Guinea (including the island of Bioko), Gabon, the Central African Republic, the Republic of the Congo, and the Democratic Republic of the Congo. Earlier records west from Nigeria refer to other species, including ''Arthroleptis krokosua'' described in 2008. Common names Buea screeching frog and variable squeaker frog have been coined for it. Etymology The specific name ''variabilis'' is Latin for "changeable". This presumably refers to the wide range of coloration and pattern seen in the species. Description ''Arthroleptis variabilis'' is a robust frog with moderately robust limbs. Males measure and females in snout–vent length. The head is somewhat broad. The tympanum is distinct and ovoid. The fingers and toes do not have webbing but there is a very prominent, flange-like inner metatarsal tubercle. Skin is smooth but tending ...

Arthroleptis
''Arthroleptis'' is a genus of frogs in the family Arthroleptidae found in tropical sub-Saharan Africa. Their common names include screeching frogs, sometimes simply squeakers. Description These species are terrestrial breeding, with direct development (metamorphosis to froglets occurs within the egg). 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 ''Arthroleptis tanneri'', the Tanzania screeching frog or Tanner's squeaker, is a species of frog in the family Arthroleptidae. It is endemic to the West Usambara Mountains in northeastern Tanzania; previous records from elsewhere refer to other ...'') 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 a ... [...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 Angola
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 dramat ...

Endemic Fauna Of Angola
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
