Homalopsis Nigroventralis
''Homalopsis'' is a genus of snakes of the family Homalopsidae. The genus is restricted to South East Asia and includes five currently recognized species. Like all members of the family Homalopsidae, ''Homalopsis'' are rear-fanged and mildly venomous, though considered harmless to humans. Habitat ''Homalopsis'' are a freshwater aquatic species that are found in a wide range of habitats including ponds, rivers, flowing streams, swamps, marshes and other wetlands. Human disturbance and activity does not seem to hinder this species as much as others and can be actively found in disturbed habitat such as man-made drainage ditches and irrigated agriculture fields.Murphy, John C. 2007. Homalopsid Snakes: Evolution in the Mud. Krieger Publishing, Malabar, Florida, 249 pp. Behavior This species is nocturnal and can be found in muddy bank holes or burrows during the day.

Homalopsis Buccata
''Homalopsis buccata'' (puff-faced water snake or masked water snake) is a species of mildly venomous snake in the Homalopsidae family found in tropical areas of Southeast Asia. Description Upper labials 1–4 contact single loreal; two prefrontals; 33–40 dorsal scale rows at mid-body, usually reduced to fewer than 30 posteriorly; one postocular plus a postsubocular; 12 (11–14) upper labials; ventral count fewer than 166. ''Homalopsis buccata'' has a banded pattern and usually reaches 1 meter (3 feet) in length. They have a somewhat similar body build to the anaconda, but instead of constriction they use a mild venom from a grooved rear fang to subdue prey. Distribution ''H. buccata'' ranges from northern Sumatra to Salanga Island, Indonesia and Borneo; it is present on the Malaysian peninsula and in extreme southern Thailand (vicinity of Pattani). Reproduction ''H. buccata'' are ovoviviparous, meaning they do not lay eggs but rather give birth to live young. Females ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Kuhl
Heinrich Kuhl (17 September 1797 – 14 September 1821) was a German people, German naturalist and zoologist. Kuhl was born in Hanau (Hesse, Germany). Between 1817 and 1820, he was the assistant of professor Th. van Swinderen, docent natural history at the University of Groningen in Groningen (the Netherlands). In 1817, he published a monograph on bats, and in 1819, he published a survey of the parrots, ''Conspectus psittacorum''. He also published the first monograph on the petrels, and a list of all the birds illustrated in Edme-Louis Daubenton, Daubenton's ''Planches Enluminées'' and with his friend Johan Coenraad van Hasselt (1797–1823) ''Beiträge zur Zoologie und vergleichenden Anatomie'' ("Contributions to Zoology and Comparative Anatomy") that were published at Frankfurt-am-Main, 1820. In 1820, he became assistant to Coenraad Jacob Temminck at the Leiden Rijksmuseum van Natuurlijke Historie. He then travelled to Java (island), Java, then part of the colonial Netherla ...

Johan Coenraad Van Hasselt
Johan Conrad van Hasselt (occasionally Johan Coenraad van Hasselt; 24 June 1797 in Doesburg – 8 September 1823), was a Dutch physician, zoologist, botanist and mycologist. Conrad van Hasselt studied medicine at the University of Groningen. In 1820 he went on an expedition to the island of Java, then part of the colonial Dutch East Indies, with his friend Heinrich Kuhl, to study the fauna and flora of the island. They sailed from Texel on 11 July, stopping at Madeira, the Cape of Good Hope and Cocos Island and arriving in Batavia on December 1820. Kuhl died after eight months, van Hasselt continued the work for another two years before dying (like Kuhl) of disease and exhaustion. This followed a journey to Bantam. They sent the Museum of Leiden 200 skeletons, 200 skins of mammals from 65 species, 2,000 bird skins, 1,400 fish, 300 reptiles and amphibians, and many insects and crustaceans .

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Homalopsidae
The Homalopsidae are a family of snakes which contains about 28 genus, genera and more than 50 species. They are commonly known as Indo-Australian water snakes, mudsnakes, or bockadams. They are also known as ''ular air'' (lit. "water snake") in Indonesian. They are typically stout-bodied water snakes, and all are mildly venomous. Two monotypic genera are notable for their unusual morphology: ''Erpeton'' possesses a pair of short, fleshy appendages protruding from the front of the snout, and ''Bitia'' has uniquely enlarged snake skull, palatine teeth. ''Cerberus (snake), Cerberus'' species have been noted to use sidewinding to cross slick Mudflat, mud flats during low tide. ''Fordonia'' and ''Gerarda (snake), Gerarda'' are the only snakes known to tear their prey apart before eating it, pulling soft-shelled crabs through their coils to rip them apart prior to ingestion.
