Asian Water Monitor
The Asian water monitor (''Varanus salvator'') is a large Varanidae, varanid lizard native to South Asia, South and Southeast Asia. It is widely considered to be the List of largest extant lizards, second-largest lizard species, after the Komodo dragon. It is distributed from eastern and northeastern India and Bangladesh, the Andaman and Nicobar Islands, Sri Lanka, through southern China and Hainan Island in the east to mainland Southeast Asia and the islands of Sumatra, Borneo, Java, Lombok, the Riau Archipelago, and Sulawesi. It is one of the most widespread monitor lizards. The Asian water monitor has a natural affinity towards water, inhabiting the surroundings of lakes, rivers, ponds, swamps and various Riparian zone, riparian habitats, including Sewerage, sewers, city parks, and urban waterways. It is an excellent swimmer and hunts fish, frogs, invertebrates, water birds, and other types of aquatic and amphibious prey. Due to its apparently large, stable population, it is ...

Josephus Nicolaus Laurenti
Josephus Nicolaus Laurenti (4 December 1735, Vienna – 17 February 1805, Vienna) was an Austrian naturalist and zoologist of Italian origin. Laurenti is considered the auctor of the class Reptilia (reptiles) through his authorship of ' (1768) on the poisonous function of reptiles and amphibians. This was an important book in herpetology, defining thirty genera of reptiles; Carl Linnaeus's 10th edition of ''Systema Naturae'' in 1758 defined only ten genera. ''Specimen Medicum'' contains a description of the blind salamander (amphibian): '' Proteus anguinus'', purportedly collected from cave waters in Slovenia (or possibly western Croatia Croatia, officially the Republic of Croatia, is a country in Central Europe, Central and Southeast Europe, on the coast of the Adriatic Sea. It borders Slovenia to the northwest, Hungary to the northeast, Serbia to the east, Bosnia and Herze ...); this description represented one of the first published accounts of a cave animal in the we ...

Riau Archipelago
The Riau Archipelago is a ''geographic'' term (as opposed to administrative region) for the core group of islands within the Riau Islands Province in Indonesia, and located south of Singapore and east of Riau on Sumatra. Before the province of Riau Islands was formed, there was no ambiguity in term; however, in Indonesian language, both the archipelago and administrative province are referred to simply as "Kepulauan Riau". The province may have the word "Provinsi" preceding it for clarity. Additionally, the term BBK for ''Batam Bintan Karimun'' may refer to the archipelago. History The name of this archipelago predates the creation of the Indonesian province, and historically did not include the Lingga Islands or Natuna Islands, which now belong to that province. On the other hand, Singapore was considered a part of the islands, at least in the Islamic eras. Srivijaya and Jambi From 650 CE–1377 CE are accepted dates for the Srivijaya empire, when the area seemed to be well wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varanus (Soterosaurus)
''Soterosaurus'' is a subgenus of monitor lizards commonly known as Southeast Asian water monitors. Most species are endemic to the Philippines, but Roughneck monitor, black rough-necked monitors, Asian water monitor, Asian water monitors, and Togian water monitor, Togian water monitors can be found elsewhere in Southeast Asia. Classification The Roughneck monitor, black rough-necked monitor (''V. rudicollis'') was previously in the closely related subgenus ''Empagusia'', but genomic analyses show it is actually the Basal (phylogenetics), basalmost member of ''Soterosaurus'', having split from the ''V. salvator'' species complex (which is composed of all the other Southeast Asian water monitor species) 14 million years ago during the middle Miocene. Behaviour These large Semiaquatic, semi-aquatic lizards have laterally flattened tails, making them excellent swimmers. While all are terrestrial, some species, especially the Roughneck monitor, black rough-necked monitor, may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 plant variety (botany), varieties), which may be a complex ranking but it is not a species complex. In most cases, a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodore Cantor
Theodore Edward Cantor () (1809–1860) was a Danish physician, zoologist and botanist. He described several new species of reptiles and amphibians, and six species have been named in his honor. Cantor was born to a Danish Jewish family; his mother was a sister of Nathaniel Wallich. Cantor worked for the British East India Company, and made natural history collections in Penang and Malacca. Career Cantor was the first Western scientist to describe the Siamese fighting fish. In the scientific field of herpetology he described many new species of reptiles and amphibians. Species first described by Cantor include '' Bungarus bungaroides'' (1839), '' Bungarus lividus'' (1839), '' Channa argus'' (1842), '' Elaphe rufodorsata'' (1842), '' Euprepiophis mandarinus'' (1842), '' Hippocampus comes'' (1850), '' Lycodon effraenis'' (1847), '' Misgurnus anguillicaudatus'' (1842), '' Naja atra'' (1842), '' Oligodon albocinctus'' (1839), '' Oligodon cyclurus'' (1839), '' Ophiophagus hannah'' ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Name
In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammar, Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the ''generic name (biology), generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Arabic (language)
Arabic (, , or , ) is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world. The International Organization for Standardization (ISO) assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as ( "the eloquent Arabic") or simply ' (). Arabic is the third most widespread official language after English and French, one of six official languages of the United Nations, and the liturgical language of Islam. Arabic is widely taught in schools and universities around the world and is used to varying degrees in workplaces, governments and the media. During the Middle Ages, Arabic was a major vehicle of culture and learning, especially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

IUCN Red List
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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...
