Aphantophryne
''Aphantophryne'' is a genus of microhylid frogs found in New Guinea and in Mindanao, the Philippines. Originally described by Fry in 1917, Richard G. Zweifel considered in 1956 ''Aphantophryne'' synonymous to ''Cophixalus''. The genus was resurrected in 1989 to house two new species in addition to the type species, '' A. pansa''. A molecular study on the subfamily Asterophryinae in 2017 revealed that two species originally included in the genus '' Oreophryne'' were more closely related to ''Aphantophryne'' than to other ''Oreophryne'', and were consequently moved to this genus. The study also revealed a number of undescribed species. Description ''Aphantophryne'' are small frogs, the maximum snout-to-vent body length is 31 mm for ''A. pansa'' and 24 mm for '' A. sabini''. The smallest species '' A. minuta'' has the body length of only 12 mm. Females are larger than males. The distinguishing feature of ''Aphantophryne'' when compared to other genyophrynine genera ...

Aphantophryne Nana
''Aphantophryne nana'' is a species of frog in the family Microhylidae. It is endemic to the Philippines and is known with certainty only from the island of Camiguin. It is unclear whether similar frogs from northeast Mindanao are referable to this species. It was described as ''Oreophryne nana'', but based on molecular data it was moved to ''Aphantophryne'' in 2017. Common names Camiguin cross frog, Camiguin narrow-mouthed frog, and volcano cross frog have been coined for the species. Description ''Aphantophryne nana'' are small, moderately slender-bodied frogs. Adult females in the type series measure in snout–vent length; no males were collected. The head is broader than it is long. The snout is short and bluntly round–pointed. The canthus rostralis is rounded. The tympanum is distinct. The fingers and the toes are dilated into moderately large disks (with the exception of the first finger). Skin is smooth. Preserved specimens are dusky brown, apart from the blackish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphantophryne Sabini
''Aphantophryne sabini'' is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from the region of its type locality, Myola Guest House in the Owen Stanley Range, Northern Province. The specific name ''sabini'' honors Andrew E. Sabin, an American businessman, philanthropist, and environmentalist who joined the expedition during which the holotype of this species was collected. However, its vernacular name Guest House Guinea frog refers to the type locality instead. Description Males can grow to and females to in snout–vent length. The overall appearance is squat, and the head is notably narrower than the rotund body. The snout is rounded. The tympanum is poorly visible. The fingers and toes have rounded tips and no webbing. The hind legs are short. The holotype has orange-tan dorsal ground color, dark brown dorsal markings, and a white vertebral stripe bordered with black. However, most specimens lack the vertebral stripe. The d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphantophryne Minuta
''Aphantophryne minuta'' is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from its type locality near Myola Guest House in the Owen Stanley Range, Northern Province, from another locality in the same province, Mount Tafa; only a single specimen is known from each locality. The specific name ''minuta'' refers to the very small size of this species. Common name Myola Guinea frog has been coined for it. Description ''Aphantophryne minuta'' was described based on a single adult female, the holotype, measuring in snout–vent length. It is very similar to ''Aphantophryne sabini'' but much smaller (mature ''A. sabini'' females measure in snout–vent length). The snout is short and rounded. The tympanum is small and only partially visible. The fingers and toes have rounded tips and no webbing. The hind legs are short. The dorsum is warty, including the scapular folds that continue backward as rows of warts. The preserved specimen is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphantophryne Parkeri
''Aphantophryne parkeri'' is a species of frog in the family Microhylidae. It is endemic to the north coast of New Guinea and only known from Matapan (or Matapau) and the Bewani Mountains in the West Sepik Province, Papua New Guinea, and from Sentani in the Papua Province, Western New Guinea (Indonesia). This species was formerly included in the genus ''Oreophryne'', but was in 2017 moved to ''Aphantophryne'' based on molecular data. The specific name ''parkeri'' honours Hampton Wildman Parker, an English zoologist and herpetologist. Common name Parker's cross frog has been coined for it. Description Adult males measure about and adult females in snout–vent length (each of these ranges is based on just two specimens). The head is relatively narrow. The snout bluntly rounded, approaching truncate, in dorsal view, and vertical in profile. The canthus rostralis is rounded. The tympanum is moderately distinct to indistinct. The fingers and the toes have well-developed termina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Dene Barrett Fry
The Dene people () are an indigenous group of First Nations who inhabit the northern boreal and Arctic regions of Canada. The Dene speak Northern Athabaskan languages. ''Dene'' is the common Athabaskan word for "people". The term "Dene" has two usages. More commonly, it is used narrowly to refer to the Athabaskan speakers of the Northwest Territories and Nunavut in Canada, especially including the Chipewyan (Denesuline), Tlicho (''Dogrib''), Yellowknives (T'atsaot'ine), Slavey (Deh Gah Got'ine or Deh Cho), and Sahtu (the Eastern group in Jeff Leer's classification; part of the Northwestern Canada group in Keren Rice's classification). However, it is sometimes also used to refer to all Northern Athabaskan speakers, who are spread in a wide range all across Alaska and northern Canada. The Southern Athabaskan speakers, however, also refer to themselves by similar words: Diné (Navajo) and Indé (Apache). Location Dene are spread through a wide region. They live in the Macke ...

Amphibian Genera
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 ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
