Cynops Orientalis
The Chinese fire belly newt (''Cynops orientalis'') is a small () black newt, with bright-orange aposematic coloration on their ventral sides. ''C. orientalis'' is commonly seen in pet stores, where it is frequently confused with the Japanese fire belly newt (''C. pyrrhogaster'') due to similarities in size and coloration. ''C. orientalis'' typically exhibits smoother skin and a rounder tail than ''C. pyrrhogaster'', and has less obvious parotoid glands. Toxicology Chinese fire belly newts are mildly poisonous and excrete toxins through their skin. Consisting primarily of tetrodotoxins, newts of the genus ''Cynops'' pose a medically significant threat if enough toxins are consumed, and toxins may cause numbness or irritation on skin contact.

Armand David
Father Armand David (7 September 1826, Espelette – 10 November 1900, Paris) was a Lazarist missionary Catholic priest as well as a zoologist and a botanist. Several species, such as Père David's deer, are named after him — being French for Father David. Biography Born in Espelette near Bayonne, in the north of Basque Country, in Pyrénées-Atlantiques ''département'' of France, he entered the Congregation of the Mission in 1848, having already displayed great fondness for the natural sciences. Ordained in 1851, he was in 1862 sent to Peking, where he began a collection of material for a museum of natural history, mainly zoological, but in which botany, geology, and palaeontology were also well represented. At the request of the French government, important specimens from his collection were sent to Paris and aroused the greatest interest. The Jardin des Plantes commissioned him to undertake scientific journeys through China to make further collection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Fire Belly Newt
The Japanese fire-bellied newt or Japanese fire-bellied salamander (''Cynops pyrrhogaster'') is a species of newt Endemism, endemic to Japan. The skin on its upper body is dark, while its lower regions are bright red, although coloration varies with age, genetics, and region. Adults are long. To deter predators, Japanese fire-bellied newts contain high levels of tetrodotoxin, a neurotoxin which is accumulated mainly from their diet. They are found on many Japanese archipelago , Japanese islands, including Honshu, Shikoku, and Kyushu. Their habitats include both natural and artificial bodies of water, as well as forests and grasslands. They breed from spring to the beginning of summer, both sexes producing pheromones when ready to mate. Eggs are laid separately, hatching after about three weeks. They grow from larval to juvenile form in between five and six months. Juveniles eat soil-dwelling prey, while adults eat a wide variety of insects, tadpoles, and the eggs of their own ...

Tetrodotoxin
Tetrodotoxin (TTX) is a potent neurotoxin. Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin. Although tetrodotoxin was discovered in these fish and found in several other animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails), it is actually produced by certain infecting or symbiotic bacteria like ''Pseudoalteromonas'', ''Pseudomonas'', and ''Vibrio'' as well as other species found in animals. Tetrodotoxin is a sodium channel blocker. It inhibits the firing of action potentials in neurons by binding to the voltage-gated sodium channels in nerve cell membranes and blocking the passage of sodium ions (responsible for the rising phase of an action potential) into the neuron. This prevents the nervous system from carrying messages and thus muscles from contracting in response to nervous stimulation. Its mechanism of action, selective blocking o ...

Cynops
The fire belly newt or fire newt is a genus (''Cynops'') of newts native to Japan and China. All of the species show bright yellow or red bellies, but this feature is not unique to this genus. Their skin contains a toxin that can be harmful if ingested. Species Species recognized as of October 2019: (A * means that the newt has been moved into the genus ''Hypselotriton'' in some classifications ) Taxonomic controversy The genus ''Cynops'' has been suggested to be due for a split, with the Chinese species being placed in a separate genus from the Japanese ones. The species '' Cynops cyanurus'' is at the centre of all this. There is much debate about the validity of ''C. cyanurus'' and '' C. chenggongensis''. All the known captive animals could be something different from ''C. cyanurus'', as they do not entirely match the original description of the species. The only known animals that match that are animals originating from Chemnitz Chemnitz (; from 1953 to 1990: Karl-Marx ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of China
China's vast and diverse landscape is home to a profound variety and abundance of wildlife. As of one of 17 megadiverse countries in the world, China has, according to one measure, 7,516 species of vertebrates including 4,936 fish, 1,269 bird, 562 mammal, 403 reptile and 346 amphibian species.

Endemic Fauna Of China
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aposematic Species
Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually possesses chemical or physical defences is not the only way to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Armand David
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
