Xenophidion
''Xenophidion'' is a genus of snakes first described in 1995, and the only genus of the monotypic family Xenophidiidae.. Commonly referred to as spinejaw snakes, this genus is found in Borneo and peninsular Malaysia. Morphology and classification This genus is taxonomically and phylogenetically challenging to classify, as these snakes possess several morphological traits that distinguish them from all other snake species; head scales with numerous sensory papillae, large prefrontal scales, and an upper jaw which has a spiny palatine process. They also lack any pelvic girdle vestiges, a left lung, or a coronoid bone. In 2004, cytochrome b sequencing suggested a sister relationship of ''Xenophidion'' to Bolyeriidae from Mauritius. Similar to ''Boyleriidae'', spinejaw snakes have a jointed maxilla. Diet, reproduction, and habitat Very little is known about this genus. Specimen dissection has revealed the presence of a partially digested skink and an oviparous mode of reproduction, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bolyeriidae
:''Common names: Mauritius snakes, Round Island boas, splitjaw snakes.'' The Bolyeriidae are a family of snakes native to Mauritius and a few islands around it, especially Round Island. They also used to be found on the island of Mauritius, but were extirpated there due to human influence and foraging pigs in particular. These snakes used to be placed in the Boidae, but are now classed as a separate family. Two monotypic genera are recognized, but only a single species is extant. Bolyeriidae appear to be most closely related to the Asian genus '' Xenophidion''. Geographic range Found in Mauritius. Genera ) Type genus In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name.

Van Wallach
Van Stanley Bartholomew Wallach (born 1947) is an American herpetologist and an expert on blindsnakes and on the systematics, internal anatomy, and taxonomy of snakes. He has contributed to the descriptions of at least 46 species of snakes and has conducted fieldwork on tropical snakes in the Philippines, Nicaragua, and the Democratic Republic of the Congo. For many years Wallach worked as a Curatorial Assistant at the Museum of Comparative Zoology at Harvard University in Cambridge, Massachusetts. He retired from the museum in 2012, but he continues to work on snake taxonomy. Wallach was the lead editor of the 1,227 page authoritative reference book ''Snakes of the World''. In the 2000s Wallach was one of several herpetologists who became embroiled in a dispute with Raymond Hoser, a self-published Australian herpetologist, over proper nomenclatorial acts. Hoser charged Wallach with attempting to name species that Hoser had already described in his self-published journal. Wallach' ...

Ulrich Manthey
Ulrich (), is a German given name, derived from Old High German ''Uodalrich'', ''Odalric''. It is composed of the elements '' uodal-'' meaning "(noble) heritage" and ''-rich'' meaning "rich, powerful". Attested from the 8th century as the name of Alamannic nobility, the name is popularly given from the high medieval period in reference to Saint Ulrich of Augsburg (canonized 993). There is also a surname Ulrich. It is most prevalent in Germany and has the highest density in SwitzerlandThis last name was found in the United States around the year 1840Most Americans with the last name were concentrated in Pennsylvania, which was home to many Pennsylvania Dutch, German immigrant communities. Nowadays in the United States, the name is distributed largely in the Pennsylvania-Ohio regio History Documents record the Old High German name ''Oadalrich'' or ''Uodalrich'' from the later 8th century in Alamannia. The related name ''Adalric'' ( Anglo-Saxon cognate '' Æthelric'') is attested ... [...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 ...

Borneo
Borneo (; id, Kalimantan) is the third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra. The island is politically divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The population in Borneo is 23,053,723 (2020 national censuses). Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. A little more than half of the island is in the Northern Hemisphere, including Brunei and the Malaysian portion, while the Indonesian portion spans the Northern and Southern hemisph ...

Mauritius
Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga and St. Brandon. The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where most of the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering . Arab sailors were the first to discover the uninhabited island, around 975, and they called it ''Dina Arobi''. The earliest discovery was in 1507 by Portuguese sailors, who otherwise took little interest in the islands. The Dutch took possession in 1598, establishing a succession of short-lived settlements over a period of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake Families
This is an overview of the suborder Serpentes, its two infraorders (subdivisions) and the family (biology), families they contain. This is the group of reptiles commonly known as snakes. Taxonomy There are two infraorders of living snakes: Alethinophidia and Scolecophidia. This separation is based primarily on comparative anatomy, morphological characteristics between family groups; however, more recently, the comparison of mitochondrial DNA has played its part. As with most taxonomic classifications, there are many different interpretations of the evolutionary relationships. This had resulted in families being moved to different infraorders, the merging or splitting of infraorders and families. For instance, many sources classify Boidae and Pythonidae as the same family, or keep others, such as Elapidae and Hydrophiidae, separate for practical reasons despite their extremely close relationship.
