Zhangixalus Aurantiventris
''Zhangixalus aurantiventris'' (common names: orange-belly treefrog, orange-bellied treefrog) is a species of frog in the family Rhacophoridae. It is endemic to Taiwan. It is known from scattered localities across Taiwan at low to mid altitudes. Description Adult males in the type series measure in snout–vent length. In a population in Taitung County, adult males measured and adult females in snout–vent length; mean male and female body mass were 8 and 15 grams, respectively. The snout is short and roundish. The tympanum is nearly circular; supratympanic fold is present. The fingers and the toes are webbed and bear discs, the former larger than the latter. Skin is smooth. The dorsum is dark green; pale yellowish spots may be present. The lips are white. The venter is orange-red. The iris is plain yellow; the pupil is vertical. The male advertisement call sounds like a low-pitched "gree", lasting about 0.4 seconds. Habitat and ecology ''Zhangixalus aurantiventris'' occ ...

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] |

Amphibians Described In 1994
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 ...

Endemic Fauna Of Taiwan
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Taiwan
At least 37 species of amphibians are native to Taiwan. This list does not include the provisionally recorded ''Fejervarya kawamurai'' nor the introduced ''Rhinella marina'' and ''Andrias davidianus''. Of these, 17 species are endemic to Taiwan. Salamander '' Echinotriton andersoni'' is considered extinct in Taiwan (but survives on the Ryukyu Islands of Japan). In addition, there are three introduced species: cane toad ''Rhinella marina'', bullfrog ''Lithobates catesbeianus'', and Chinese giant salamander ''Andrias davidianus''. Thus, in total 40 amphibians have been recorded in Taiwan.

Zhangixalus
''Zhangixalus'' is a genus of frogs in the subfamily Rhacophorinae, family (biology), family Rhacophoridae. They are collectively known as Zhang's treefrogs. They occur in the Eastern Himalayas, southern China, Taiwan, Japan, and southeast Asia. Etymology The name of the genus honors Zhang Ya-Ping from the Chinese Academy of Sciences, in recognition to his contributions to biodiversity and evolution research in China, in combination with ''ixalus'', a common generic root for treefrogs. Taxonomy ''Zhangixalus'' was erected in a 2019 revision of the then very large genus ''Rhacophorus'' (92 species) that was split in three lineages: ''Rhacophorus'' sensu stricto (then 39 species; as of November 2021, 43 species), resurrected ''Leptomantis'' (then 14 species; as of November 2021, 13 species), and ''Zhangixalus'' (then 37 species; as of November 2021, 40 species). The split was based on molecular data, but was supported by morphological characteristics and differences in geographic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to International Unio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhacophoridae
The Rhacophoridae are a family of frogs that occur in tropical sub-Saharan Africa, South India and Sri Lanka, Japan, northeastern India to eastern China and Taiwan, south through the Philippines and Greater Sundas, and Sulawesi. They are commonly known as shrub frogs, or more ambiguously as " moss frogs" or " bush frogs". Some Rhacophoridae are called "tree frogs". Among the most spectacular members of this family are numerous "flying frogs". Although a few groups are primarily terrestrial, rhacophorids are predominantly arboreal treefrogs. Mating frogs, while in amplexus, hold on to a branch, and beat their legs to form a foam. The eggs are laid in the foam and covered with seminal fluid before the foam hardens into a protective casing. In some species, this is done in a large group. The foam is laid above a water source so the tadpoles fall into the water once they hatch. The species within this family vary in size from . Like other arboreal frogs, they have toe discs, and thos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris (anatomy)
In humans and most mammals and birds, the iris (plural: ''irides'' or ''irises'') is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. Eye color is defined by the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Structure The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles ( dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. The sphincter pupillae is the opposing muscle of the dilator pupillae. The pupil's diameter, and thus the inner border of the iris, changes size when constricting or dilating. The outer border of the iris does not change size. The constricti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
