Pseudaspididae
Pseudaspididae is a small family of elapoid snakes. They were formerly placed as a subfamily of the Lamprophiidae, but have been more recently identified as a distinct family. They have a disjunct distribution; two species (each in their own monotypic genus) are known from sub-Saharan Africa, while the two '' Psammodynastes'' species inhabit Southeast Asia. Genera The family contains four species in three genera. * ''Pseudaspis'' Fitzinger, 1843 ** ''Pseudaspis cana'' (Linnaeus, 1758) (mole snake) * ''Pythonodipsas'' Günther, 1868 ** ''Pythonodipsas carinata The western keeled snake (''Pythonodipsas carinata'') is a species of snake in the family Pseudaspididae.

Pseudaspis
The mole snake (''Pseudaspis cana'') is a species of snake. It has been placed in the family Lamprophiidae, and more recently in the family Pseudaspididae, along with the genus ''Pythonodipsas''. It is native to much of southern Africa, and is the only member of the genus ''Pseudaspis''. A study showed that ''P. cana'' is caught and consumed by the honey badger, among other species. Remains of the mole snake were found in the faeces, and suggest the consumed individuals were larger specimens. Taxonomy ''P. cana'' was originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. Its original binomial name was ''Coluber cana''. Since then, it has also been called ''Coronella cana'' by André Marie Constant Duméril, Gabriel Bibron and Auguste Duméril in 1854, before being reclassified as ''Pseudaspis cana'' by Edward Drinker Cope in 1864. ''P. cana'' is the only species in genus ''Pseudaspis''. The genus has been placed in the family Lampro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elapoidea
The Elapoidea are a Superfamily (biology), superfamily of snakes in the clade Colubroides, traditionally comprising the families Lamprophiidae and Elapidae. Advanced genomic sequence studies, however, have found lamprophiids to be paraphyletic in respect to elapids. In describing the subfamily Cyclocorinae, Weinell et al. (2017) suggested some or all subfamilies of Lamprophiidae should be reevaluated at full family status as a way to prevent the alternative, which is classifying them as elapids. This was followed in later studies such as Zaher et al. (2019). The Reptile Database considers Elapoidea to be synonymous with its sister group Colubroidea (in contrast to other studies that distinguish between both), as it does not recognize the division of Colubridae into multiple families that comprise Colubroidea, and thus instead considers Colubroidea to be composed of Colubridae + the multiple families comprising Elapoidea.

Pythonodipsas Carinata
The western keeled snake (''Pythonodipsas carinata'') is a species of snake in the family Pseudaspididae. It is native to western Namibia, southwestern Angola, and southwestern Zambia, and is the monotypic taxon, only member of the genus ''Pythonodipsas''. Taxonomy ''P. carinata'' is most closely related to ''Pseudaspis cana''. Together these two monotypic genera make up the subfamily Pseudaspidinae of the family Lamprophiidae. ''Pythonodipsas'' closely resembles the Colubrinae, colubrine genus ''Spalerosophis'', although the two are not closely related. Description ''P. carinata'' is unusual in possessing greatly fragmented head shields, a peculiar maxillary dentition (3rd to 6th largest, posterior-most tooth large and grooved), a reduced number of palatine teeth (including a greatly enlarged "fang"), and hypapophyses developed throughout the vertebral column. It was once thought to be a possible evolutionary intermediate between vipers and non-venomous Colubroidea, colubroi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snakes
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, D ...

Psammodynastes Pulverulentus
''Psammodynastes pulverulentus'', the common mock viper, is a species of snake native to Asia. Mock viper is a small snake (total length up to , less in males), but it will form defensive coils and strike in viper-like fashion when threatened. Distribution The common mock viper is known from Bangladesh, Myanmar (Burma), Cambodia, China (Fujian, Yunnan, Guangxi, Guangdong, Hainan,Hong Kong), north-eastern India (Assam, Sikkim, Darjelling;Jalpaiguri; Meghalaya, Arunachal Pradesh), Bhutan, Indonesia (Bali, Bangka, Borneo, Butung, Enggano, Flores, Java, Kalimantan, Komodo, Lombok, Mentawai Archipelago, Natuna Archipelago, Padar, Riau Archipelago, Rinca, Sangihe Archipelago, Sulawesi, Sula Archipelago, Sumatra, Sumba, Sumbawa, Togian Archipelago), Laos, Malaysia (Malaya and East Malaysia, Pulau Tioman), Nepal, the Philippines (Balabac, Basilan, Bohol, Bongao, Busuanga, Dinagat, Jolo, Leyte, Luzon, Mindanao, Negros, Palawan, Panay, Polillo, Samar), Taiwan, Thailand (incl.

Lamprophiidae
The Lamprophiidae are a family of snakes found throughout much of Africa, including the Seychelles. There are 89 species as of July 2022. Biology Lamprophiids are a very diverse group of snakes. Many are terrestrial but some are fossorial (e.g. ''Amblyodipsas'') or semi-aquatic (e.g. ''Lycodonomorphus''). Some are fast-moving (e.g. ''Psammophis'') whereas others are slow (e.g. ''Duberria''). They are found in deserts, grasslands, tropical forests and mountains. Together they feed on mammals, birds, reptiles, amphibians, fish, and invertebrates. Some species use constriction to subdue their prey (e.g. ''Boaedon''). When other snake families were formerly included within the Lamprophiidae, they were considered even more diverse in biology, although this is now known to not be the case. Most species are oviparous. Classification Most lamprophiids were historically considered to be members of the subfamily Lamprophiinae in the family Colubridae. The following classification follows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the List of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The Regions of the African Union, African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
