Anomaloglossus Ayarzaguenai
''Anomaloglossus ayarzaguenai'' (in Spanish: ''sapito ninera de Ayarzaguena'') is a species of frog in the family Aromobatidae. It is endemic to Venezuela where it is known from Cerro Jaua in Bolívar state. It is common on the top of this tepui where it is found on the margins of streams and in the surrounding forest. The only known population's home is in a protected area; formerly in Jaua-Sarisariñama National Park the habitat in question and the rest of Jaua-Sarisariñama was included within a new national park Caura National Park The Caura National Park ( es, Parque nacional Caura) is a protected area with the status of National Park in Venezuela.

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] |
Aromobatidae
The Aromobatidae are a family of frogs native to Central and South America. They are sometimes referred to as cryptic forest frogs or cryptic poison frogs. They are the sister taxon of the Dendrobatidae, the poison dart frogs, but are not as toxic as most dendrobatids are. Taxonomy The Aromobatidae were separated from the Dendrobatidae only in 2006, and some sources continue to treat these frogs as part of the Dendrobatidae. However, their position as the sister taxa is well supported, and the question is primarily about whether they should be ranked as a family or a subfamily. The validity of subfamilies within the Aromobatidae is also unsettled. Some evidence points to paraphyly of at least the subfamily Anomaloglossinae, and genus ''Allobates'', largely because of the uncertain placement of ''Allobates olfersioides''. Some species are reported to have a skunk like odor. This strong odor is secreted through the skin but theses frogs are not toxic. This strong odor is used as a ...

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] |

Bolívar (state)
Bolívar ( es, Estado Bolívar, ) is one of the 23 states of Venezuela. The state capital city is Ciudad Bolívar, but the largest city is Ciudad Guayana. Bolívar State covers a total surface area of and as of the 2011 census, had a population of 1,410,964. The state contains Angel Falls. History Spanish Colonization During the time of the Spanish Empire, it was part of the province of Nueva Andalucía and later it was annexed to the province of Guayana from 1777 when King Charles III created the Captaincy General of Venezuela. The capital of the state, Ciudad Bolivar was founded on December 21, 1595 by Antonio de Berrío, who had come from Nueva Granada (present-day Colombia) with the mission of populating Guyana. The town, originally called Santo Tomás de Guayana, was a fortified port that had to move three times, since it was the target of constant assaults by Caribbean Indians and European corsairs, among whom Sir Walter Raleigh stood out in 1617. In 1764 it foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tepui
A tepui , or tepuy (), is a table-top mountain or mesa found in South America, especially in Venezuela and western Guyana. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Some of the most outstanding tepuis are Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle, giving rise to spectacular natural scenery. Auyantepui is the source of Angel Falls, the world's tallest waterfall. Morphology These table-top mountains are the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro.

Anomaloglossus
''Anomaloglossus'' is a genus of frogs in the family Aromobatidae. The genus is endemic to the Guiana Shield in northern South America. It used to be placed in the family Dendrobatidae (together with other genera in the current Aromobatidae), and is still placed in that family by some sources. The name of the genus, from the Greek ''anomalos'' (=irregular, unusual) and ''glossa'' (=tongue), refers to the unusual tongue bearing the median lingual process, the only unambiguous phenotypic synapomorphy of this genus. Description ''Anomaloglossus'' are characterized by cryptic dorsal coloration (brown or gray). Dorsal skin is posteriorly granular. The toes are webbed, ranging from basal to extensive. The fingers have weakly expanded discs. Many species show large intraspecific morphological variability and lack of morphological characters that would allow easy species identification.

Amphibians Of Venezuela
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 decline ...
