Amphisbaenia is a group of usually legless squamates, comprising over 200 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes. As many species have a pink body and scales arranged in rings, they have a superficial resemblance to earthworms. While the genus Bipes retains forelimbs, all other genera are limbless. Although superficially similar to the snakes and blind lizards, recent phylogenetic studies suggest that they are most closely related to wall lizards of the family Lacertidae. Amphisbaenians are widely distributed, occurring in North America, Europe, Africa, South America, Western Asia and the Caribbean. They are not found east of the Caspian Sea. Most species are less than 6 inches (150 mm) long.
Garter snake is a common name for generally harmless, small to medium-sized snakes belonging to the genus Thamnophis in the family Colubridae. Native to North and Central America, species in the genus Thamnophis can be found from the subarctic plains of Canada to Costa Rica.
The Leptotyphlopidae are a family of snakes found in North America, South America, Africa and Asia. All are fossorial and adapted to burrowing, feeding on ants and termites. Two subfamilies are recognized.
Pantherophis is a genus of nonvenomous colubrid snakes endemic to central and eastern regions of North America. It consists of the North American ratsnakes, the foxsnakes, and the cornsnakes. The genus, which contains 10 recognized species, first appeared in the fossil record in the Middle Miocene around 16.3 million years ago. They are a large terrestrial snake genus that lack subocular scales. Originally classified in the genus Elaphe, phylogenetic studies have found this taxon to be closely related to Pituophis. As with all snakes Pantherophis is an obligate faunivore with a diet that consists of small mammals, birds, reptiles and amphibians, and even insects. While many species conservation status is categorized as "least concern", many local populations in some species have declined where some places have them listed as federally protected. The corn snake is a popular pet reptile, due to the availability of captive-bred animals, their low maintenance and calm disposition, and the variety of color morphs. There are other species of Pantherophis that are in the pet trade, though are not as popular as the corn snake.
Lamprophis is a genus of medium-sized, nonvenomous snakes commonly referred to as African house snakes.
The Natricinae are a subfamily of colubroid snakes, sometimes referred to as a family (Natricidae). The subfamily comprises 37 genera. Members include many very common snake species, such as the European grass snakes, and the North American water snakes and garter snakes. Some Old World members of the subfamily are known as keelbacks, because their dorsal scales exhibit strong keeling.
Gonionotophis is a genus of snakes, known commonly as African ground snakes and file snakes, in the family Lamprophiidae. The genus is endemic to Central Africa.
Hormonotus is a genus of snakes. At present, this genus is monotypic, as there is only one commonly accepted species in it, Hormonotus modestus, commonly known as the Uganda house snake or yellow forest snake. It is widespread in tropical Africa. Its sister taxon is Inyoka swazicus, the Swazi rock snake.
The Colubrinae are a subfamily of the family Colubridae of snakes. It includes numerous genera, and although taxonomic sources often disagree on the exact number, The Reptile Database lists 717 species in 92 genera as of September 2019. It is the second largest subfamily of colubrids, after Dipsadinae. Many of the most commonly known snakes are members of this subfamily, including rat snakes, king snakes, milk snakes, vine snakes, and indigo snakes.
The Alethinophidia are an infraorder of snakes that includes all snakes other than blind snakes and thread snakes. Snakes have long been grouped into families within Alethinophidia based on their morphology, especially that of their teeth. More modern phylogenetic hypotheses using genetic data support the recognition of 19 extant families, although the taxonomy of alethinophidian snakes has long been debated, and ultimately the decision whether to assign a particular clade to a particular Linnaean rank is arbitrary.
Lycodonomorphus is a genus of snakes commonly referred to as African water snakes. They are small, nonvenomous snakes, with all members being endemic to Africa, especially Tanzania.
Boaedon is a genus of African lamprophiids consisting of the "brown" house snakes. The genus was originally described by Duméril but the species contained were reclassified as Lamprophis by Fitzinger in 1843, this taxonomy remained widely accepted until November 2010 when a phylogenetic study was published by C.M.R Kelly et al. who resurrected the Boaedon clade. Although commonly regarded as belonging to the Colubridae, primary literature usually lists them, and related species, as belonging to the family Lamprophiidae within the superfamily which includes the venomous cobras and mambas, Elapoidea.
Inyoka is a monotypic genus of southern African snakes. The word "inyoka" means "snake" in Zulu, Xhosa, Swahili, Shona and other African languages. These snakes were previously grouped in the genus Lamprophis but were found to be closer related to Hormonotus; a substantial genetic divergence between them and a 1900 km gap between their geographic ranges meant a new genus was erected for Lamprophis swazicus, the sole species of the new genus.
Boaedon lineatus, the striped house snake, is a species of lamprophiid from throughout Africa. This species has a wide range stretching from Tanzania through Central Africa as far as Uganda. They are kept as pets with increasing regularity, often captured and exported for the pet trade. Until November 2010, this species was grouped in the genus Lamprophis, but a paper published by Kelly et al. reclassified this species in the genus Boaedon.
Boaedon capensis, the Cape house snake, also known as the brown house snake, is a species of lamprophiid from Botswana, South Africa, Mozambique, Zambia and Zimbabwe. They are a non-venomous lamprophiid. This species was previously grouped in the genus Lamprophis but is regrouped with the genus Boaedon.
The Lamprophiidae are a family of snakes found mostly in Africa, but also in parts of southern Europe and western Asia. A few species reach southeastern Asia. There are 322 species as of April 2019.
Dipsadinae is a large subfamily of colubroid snakes, sometimes referred to as a family (Dipsadidae). They are found in most of the Americas, including the West Indies, and are most diverse in South America. There are more than 700 species.
Lamprophiinae is a subfamily of lamprophiid snakes, a large group of mostly African snakes, most of which were formerly classified as colubrids but which we now know are actually more closely related to elapids.
Lycodonomorphus inornatus, commonly known as the olive house snake, the black house snake, and the olive ground snake, is a species of nonvenomous snake in the family Lamprophiidae. The species is endemic to southern Africa. It is a nocturnal snake with terrestrial habits.
The black file snake, also known commonly as the dwarf file snake or the Nyassa file snake, is a species of snake in the subfamily Lamprophiinae of the family Lamprophiidae. The species is endemic to Africa.
