Calluella Volzi
''Glyphoglossus volzi'', also known as Sumatra squat frog, is a species of frog in the family Microhylidae. It is endemic to Sumatra, Indonesia. The specific name ''volzi'' honours Dr Walter Volz, a Swiss zoologist and traveller. ''Glyphoglossus volzi'' is a poorly known species occurring in lowland primary forest at elevations of above sea level. It is only known from few specimens, but this likely reflects the lack of suitable sampling methods for what is likely a fossorial species. It probably lays its eggs in pools of standing water on the forest floor. The main threat to this species is clear-cutting of lowland tropical rainforest for oil palm plantations, small-holder agriculture, and wood extraction. It is present in the Bukit Barisan Selatan National Park Bukit Barisan Selatan National Park is a national park in Sumatra, Indonesia. The park located along the Bukit Barisan mountain range, has a total area of 3,568 km2, and spans three provinces: Lampung, Bengkulu, ...

Pieter Nicolaas Van Kampen
Pieter Nicolaas van Kampen (30 June 1878, Amsterdam – 3 July 1937, Leiden) was a Dutch zoologist. In 1904 he received his PhD from the University of Amsterdam, where he was a student and assistant to Max Carl Wilhelm Weber. From 1905 to 1911 he was based in the Dutch East Indies, during which time, he was assigned to the Aru Islands (1907) and participated in an expedition to Netherlands New Guinea (1910). In 1911 he returned to Amsterdam as a zoological assistant at the university. From 1917 to 1931 he served as a professor at the University of Leiden. Taxa He is the taxonomic author of the frog genera ''Choerophryne'', '' Nesobia'' ( junior homonym), and ''Oxydactyla'', as well as of numerous amphibian species. With Hilbrand Boschma, he described a number of species within the barnacle genus '' Sacculina''. His name is associated with the following species: * '' Hylarana kampeni'' (Bander Baru frog); circumscribed by George Albert Boulenger, 1920. * '' Nactus vankampe ...

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 ...

Microhylidae
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 63 genera and 11 subfamilies, which is the largest number of genera of any frog family. Evolution A molecular phylogenetic study by van der Meijden, et al. (2007) has estimated the initial internal divergence of the family Microhylidae to have taken place about 66 million years ago, or immediately after the Cretaceous extinction event. The most recent common ancestor of the Microhylidae and their closest ranoid relatives is estimated to have lived 116 million years ago in Gondwana. Description As suggested by their name, microhylids are mostly small frogs. Many species are below in length, although some species are as large as . They can be arboreal or terrestrial, and some even live close to water. The ground-dwellers are often found under leaf litter within forests, occasionally venturing out at night to hunt. The two main shapes for the microhyli ...

Endemic
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 ...

Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...

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 ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Fossorial
A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some examples are badgers, naked mole-rats, clams, meerkats, and mole salamanders, as well as many beetles, wasps, and bees. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many prehistoric phyla and taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single family. Fossorial animals appeared simultaneously with the colonization of land by arthropods in the late Ordovician period (over 440 million years ago). Other notable early burrowers include ''Eocaecilia'' and possibly ''Dinilysia''. The oldest example of burrowing in synapsids, the lineage which includes modern mammals and their ancestors, is a cynodont, ''Thrinaxodon liorhinus'', found in the Karoo of South Africa, estimated to be 251 million years old. Evidence shows that this ...

Glyphoglossus
''Glyphoglossus'' is a genus of frogs in the family Microhylidae. The genus occurs in Southeastern Asia. Common name balloon frogs has been coined for it, whereas the common name squat frogs refers to the ''Calluella'' species that are now included in this genus. They are fossorial frogs that spend only limited time on the soil surface and are typically known from only few specimens. Taxonomy ''Glyphoglossus'', as currently delimited, includes species formerly included in a separate genus, ''Calluella''. Molecular genetic data strongly suggest that ''Glyphoglossus'' is nested within ''Calluella''. Consequently, ''Calluella'' was brought into synonymy of ''Glyphoglossus''. Description Diagnostic characteristics of ''Calluella'' are wide head and flattened body; reduced eyes; presence of maxillary and vomerine teeth; toes with reduced webbing; circular pupil; large, oval, and entire tongue; palate having paired dermal ridges; and a large compressed inner metatarsal The metata ...

Amphibians Of Indonesia
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 declin ...
