Asterophrys Turpicola
''Asterophrys turpicola'' (common name: New Guinea bush frog) is a species of frog in the family Microhylidae. It is widespread in New Guinea and found in both West Papua (Indonesia) and Papua New Guinea, although it appears to be absent from the eastern half of Papua New Guinea. It also occurs on the island of Yapen, off the north-western coast of New Guinea. The species is known for its aggressive behaviour: it can attack and bite viciously. Description ''Asterophrys turpicola'' grows to a maximum size of in snout–vent length. The head is very broad, as wide as the body. There is an elongated, spine-like tubercle on each eyelid, and two prominent tubercles on the lower jaw. The tongue is blue. The fingers and toes have expanded discs. The colouration is drab with shades of brown and black, but the hands and feet are pigmented. The limbs and sides of the body bears warts. Behaviour ''Asterophrys turpicola'' shows unusual defensive behaviours: when threatened, the frog takes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphibians Described In 1837
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 dec ...

Asterophrys
''Asterophrys'' is a genus of microhylid frogs found in New Guinea. Their common name is New Guinea bush frogs, although this name may also specifically refer to '' Asterophrys turpicola''. ''Asterophrys'' are moderate to large-sized microhylid frogs, with the larger '' Asterophrys turpicola'' measuring up to in snout–vent length. A distinctive feature of these frogs is their extremely broad head, almost half of snout–vent length. While both are New Guinean species, ''A. leucopus'' is more a mountain species than ''A. turpicola''. The latter is known for its aggressiveness (it may even bite), whereas ''A. leucopus'' is more docile. Species The following species are recognised in the genus ''Asterophrys'': A third, undescribed species may exist in Papua Papua most commonly refers to: * New Guinea, the world's second-largest island in the southwestern Pacific Ocean * Western New Guinea, the western half of the island of New Guinea, which is administered by Indonesia. ** Papu ...

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 obje ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterophrys Leucopus
''Asterophrys leucopus'' is a species of frog in the family Microhylidae. It is endemic to northwestern Papua New Guinea where it is known from three locations: Stolle Mountain in the Sandaun Province—its type locality, and Hunstein Mountains in the East Sepik Province and the Bewani Mountains in the West Sepik Province. Description ''Asterophrys leucopus'' are moderately large microhylids. The three males in the type series measure in snout–vent length. A distinctive feature of these frogs, shared with the congeneric ''Asterophrys turpicola'', is their extremely broad head, almost half of snout–vent length. The body is robust with short limbs. The colour pattern is mottled light and dark pinkish brown, with irregular black patches on dorsal and lateral surfaces; this gives these frogs a good camouflage against wet moss of their habitat. Males call from exposed positions; the call consists of a series of rapidly repeated introductory notes followed by slower terminal notes. ...

Frog
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the 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 dating suggests their split from other amphibians may extend further back to the Permian, 265 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 or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs ...

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 such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Because tails are often missing or absent, especially in juveniles, SVL is seen as more invariant than total length. Even in the case of crocodiles, tail tips may be missing. Methods The measurements may be taken with dial calipers or digital calipe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yapen
Yapen (also Japan, Jobi) is an island of Papua, Indonesia. The Yapen Strait separates Yapen and the Biak Islands to the north. It is in Cenderawasih Bay off the north-western coast of the island of New Guinea. To the west is Mios Num Island across the Mios Num Strait, and to the east Kurudu Island. Off the southeast coast of Yapen are the Amboi Islands and to the southwest are the Kuran Islands. Together these islands form the Yapen Islands Regency within the province of Papua. It is populated with communities of Yobi, Randowaya, Serui, and Ansus. Its highest point is . First recorded sighting by Europeans is by Spanish navigator Álvaro de Saavedra who landed on 24 June 1528 when trying to return from Tidore to New Spain. It was then charted as ''Paine'' within the ''Islas de Oro'' (Golden Islands in Spanish), as they called Yapen and the present day Schoutens. In 1545 it was visited by Íñigo Órtiz de Retes on board of galleon Galleons were large, mult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
