Kurixalus Wangi
''Kurixalus wangi'' is a species of tree frog in the family Rhacophoridae. It is endemic to Taiwan and occurs in the southernmost part of the island. Prior to its description in 2016, it was confused with ''Kurixalus eiffingeri''. The specific name ''wangi'' honors Wang Ching-Shong, a pioneering herpetologist from Taiwan. Taxonomy and systematics ''Kurixalus wangi'' was described in 2016. It resembles ''Kurixalus eiffingeri'' but displays some morphological differences and a different reproductive season. Furthermore, molecular data and male advertisement call differentiate it from ''Kurixalus eiffingeri'' and ''Kurixalus berylliniris'', its sister species. Together these three species form a lineage that is clearly separate from '' Kurixalus idiootocus'', the fourth ''Kurixalus'' species in Taiwan. Description Adult males measure and adult females in snout–vent length. The overall appearance is slender with flat body. The head is wider than it is long. The snout is subovoid ...

Tree Frog
A tree frog (or treefrog) is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state. Several lineages of frogs among the Neobatrachia have given rise to treefrogs, although they are not closely related to each other. Millions of years of convergent evolution have resulted in very similar morphology even in species that are not very closely related. Furthermore, tree frogs in seasonally arid environments have adapted an extra-epidermal layer of lipid and mucus as an evolutionary convergent response to accommodate the periodic dehydration stress. Description As the name implies, these frogs are typically found in trees or other high-growing vegetation. They do not normally descend to the ground, except to mate and spawn, though some build foam nests on leaves and rarely leave the trees at all as adults. Tree frogs are usually tiny as their weight has to be carried by the branches and twigs in their habitats. While some reach 10 ...

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 Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Bec ... [...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''.

Kurixalus
''Kurixalus'' is a genus of frogs in the family Rhacophoridae. The taxonomy of small rhacophids is difficult and has been subject to many revisions, but molecular genetic data do support monophyly of ''Kurixalus''. These frogs are distributed from Himalayan front ranges of eastern India southward and eastward to Cambodia, Vietnam, southern China, Taiwan, and the Ryukyu Islands.

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.

Oophagous
Oophagy ( ) sometimes ovophagy, literally "egg eating", is the practice of embryos feeding on eggs produced by the ovary while still inside the mother's uterus. The word oophagy is formed from the classical Greek (, "egg") and classical Greek (, "to eat"). In contrast, adelphophagy is the cannibalism of a multi-celled embryo. Oophagy is thought to occur in all sharks in the order Lamniformes and has been recorded in the bigeye thresher (''Alopias superciliosus''), the pelagic thresher (''A. pelagicus''), the shortfin mako (''Isurus oxyrinchus'') and the porbeagle (''Lamna nasus'') among others. It also occurs in the tawny nurse shark (''Nebrius ferrugineus''), and in the family Pseudotriakidae. This practice may lead to larger embryos or prepare the embryo for a predatory lifestyle. There are variations in the extent of oophagy among the different shark species. The grey nurse shark (''Carcharias taurus'') practices intrauterine cannibalism, the first developed embryo consuming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pingtung County
Pingtung County is a county located in southern Taiwan. It has a warm tropical monsoon climate and is known for its agriculture and tourism. Kenting National Park, Taiwan's oldest national park, is located in the county. The county seat is Pingtung City. Name The name ''Pingtung'' means "east of Banping mountain", referring to a nearby mountain known as Banping mountain (). History Early history Aboriginal inhabitants of Liuqiu Island (13 km misouthwest of Taiwan, and now part of Pingtung County) killed Dutch sailors on two occasions. In response, in the spring of 1636, Dutch sailors carried out a punitive campaign that became known as the Lamey Island Massacre. Modern-day Pingtung County and Kaohsiung City were part of Banlian-chiu (萬年州; ''Bān-liân-chiu'') during the Kingdom of Tungning (1661–1683) and Fongshan Prefecture (鳳山縣; ''Hōng-soaⁿ-koān'') during Qing dynasty rule (1683–1895).

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] |
Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

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] |
