Asterophrys
''Asterophrys'' is a genus of microhylid frogs found in New Guinea New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is .... 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.

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] |
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 not ...

Asterophrys Eurydactyla
''Asterophrys eurydactyla'' is a species of frog in the family Microhylidae. It is endemic to New Guinea and known from the Onin Peninsula in Western New Guinea (Indonesia), and from the Star Mountains in the Western Province in Papua New Guinea, close to the border with Western New Guinea; there are some doubts whether this easternmost record is conspecific with ''A. eurydactyla''. Common name Danowaria callulops frog has been proposed for this species. ''Asterophrys eurydactyla'' occurs in tropical lowland, hill, and montane rainforests, including a limestone cave. It is known from elevations between above sea level Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level .... There are no known major threats to this species. It is not known to occur in any protected areas. References ...

Asterophrys Pullifer
''Asterophrys pullifer'' is a species of frog in the family Microhylidae. It is endemic to New Guinea and known from the Wondiwoi Mountains at the base of the Wandammen Peninsula in Western New Guinea (Indonesia), and from the Mount Shungol and Bowutu Mountains in Papua New Guinea Papua New Guinea, officially the Independent State of Papua New Guinea, is an island country in Oceania that comprises the eastern half of the island of New Guinea and offshore islands in Melanesia, a region of the southwestern Pacific Ocean n ....

Asterophrys Slateri
''Asterophrys slateri'' is a species of frog in the family Microhylidae. It is found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and heavily degraded former forest. It is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ....

Microhylidae
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family (biology), family of frogs. The 683 species are in 57 genera and 11 subfamilies. 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 Ranoidea, 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 microhylids are wide bodies and narrow mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Jakob Von Tschudi
Johann Jakob von Tschudi (25 July 1818 – 8 October 1889) was a Switzerland, Swiss naturalist, explorer, and diplomat. He is known for his travels in South America, his scientific contributions to zoology and anthropology, and his diplomatic service for Switzerland. Early life and education Tschudi was born in Glarus to Johann Jakob Tschudi, a merchant, and Anna Maria Zwicky. He studied natural sciences and medicine at the universities of Neuchâtel, Leiden, and Paris. Exploration and scientific work In 1838, Tschudi travelled to Peru, where he remained for five years exploring and collecting plants in the Andes. He moved to Vienna in 1843. In 1845, he described 18 new species of South American reptiles. Between 1857 and 1859, he visited Brazil and other countries in South America. Tschudi wrote a textbook on Peru titled ''Peruvian Antiquities'' in which he recorded various aspects of Peruvian life and history. In the book, he explained the various skull angles of Peruvians in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...
