Booidea
The Booidea, also known as booid snakes, are a superfamily of snakes that contains boas (family Boidae) and other closely related boa-like snakes (but not pythons, which are in a separate superfamily called Pythonoidea). As of 2017, Booidea contains 61 species, including the eponymous neotropical ''Boa constrictor'', anacondas (genus '' Eunectes''), and smaller tree and rainbow boas ('' Corallus'', '' Epicrates'', and ''Chilabothrus'') as well as several genera of booid snakes from various locations around the world: bevel-nosed boas or keel-scaled boas ('' Candoia'') from New Guinea and Melanesia, Old World sand boas ('' Eryx'') from Northeast Africa, the Middle East, and Southwest Asia, rubber boas (''Charina'') and rosy boas ('' Lichanura'') from North America, neotropical dwarf boas ('' Ungaliophis'') and the Oaxacan dwarf boa ('' Exiliboa'') from Central America, Madagascan boas or Malagasy boas ('' Acrantophis'' and '' Sanzinia'') from Madagascar, and the Calabar python (''Ca ...

Python (genus)
''Python'' is a genus of constricting snakes in the Pythonidae family native to the tropics and subtropics of the Eastern Hemisphere. The name ''Python'' was proposed by François Marie Daudin in 1803 for non-venomous flecked snakes. Currently, 10 python species are recognized as valid taxa. Three formerly considered python subspecies have been promoted, and a new species recognized. Taxonomy The generic name ''Python'' was proposed by François Marie Daudin in 1803 for non-venomous snakes with a flecked skin and a long split tongue. In 1993, seven python species were recognized as valid taxa. On the basis of phylogenetic analyses, between seven and 13 python species are recognized. Distribution and habitat In Africa, pythons are native to the tropics south of the Sahara, but not in the extreme south-western tip of southern Africa (Western Cape) or in Madagascar. In Asia, they occur from Bangladesh, Nepal, India, Pakistan, and Sri Lanka, including the Nicobar Islands, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pythonoidea
The Pythonoidea, also known as pythonoid snakes, are a superfamily of snakes that contains pythons (family Pythonidae) and other closely related python-like snakes (but not boas, which are in a separate superfamily called Booidea). As of 2022, Pythonoidea contains 39 species, including the eponymous genus ''Python'' and 10 other genera of pythons ('' Antaresia'', '' Apodora'', '' Aspidites'', '' Bothrochilus'', '' Leiopython'', ''Liasis'', '' Malayopython'', ''Morelia'', '' Nyctophilopthon'' and '' Simalia''), all in the family Pythonidae, as well as two lesser-known families, Loxocemidae (one species, the Mexican burrowing python, in the genus '' Loxocemus'') and Xenopeltidae (two species of sunbeam snakes in the genus '' Xenopeltis''). The taxonomy of pythons, boas, and other henophidian snakes has long been debated, and ultimately the decision whether to assign a particular clade to a particular Linnaean rank (such as a superfamily, family Family (from la, familia) is ...

Snake
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 Amphisbaen ...

Boidae
The Boidae, commonly known as boas or boids, are a family of nonvenomous snakes primarily found in the Americas, as well as Africa, Europe, Asia, and some Pacific Islands. Boas include some of the world's largest snakes, with the green anaconda of South America being the heaviest and second-longest snake known; in general, adults are medium to large in size, with females usually larger than the males. Five subfamilies, comprising 12 genera and 49 species, are currently recognized. The Old Tupi name for such snakes was mbói, which figures in the etymology of names such as ''jibóia'' and ''boitatá'' (the Brazilian name for the mythical giant anaconda). Description Like the pythons, boas have elongated supratemporal bones. The quadrate bones are also elongated, but not as much, while both are capable of moving freely so when they swing sideways to their maximum extent, the distance between the hinges of the lower jaw is greatly increased.Parker HW, Grandison AGC. 1977.

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nom ....

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 opin ...

Superfamily (zoology)
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

Linnaean Taxonomy
Linnaean taxonomy can mean either of two related concepts: # The particular form of biological classification (taxonomy) set up by Carl Linnaeus, as set forth in his ''Systema Naturae'' (1735) and subsequent works. In the taxonomy of Linnaeus there are three kingdoms, divided into ''classes'', and they, in turn, into lower ranks in a hierarchical order. # A term for rank-based classification of organisms, in general. That is, taxonomy in the traditional sense of the word: rank-based scientific classification. This term is especially used as opposed to cladistic systematics, which groups organisms into clades. It is attributed to Linnaeus, although he neither invented the concept of ranked classification (it goes back to Plato and Aristotle) nor gave it its present form. In fact, it does not have an exact present form, as "Linnaean taxonomy" as such does not really exist: it is a collective (abstracting) term for what actually are several separate fields, which use similar appr ...

Calabar Python
:''Common names: Calabar ground boa, burrowing boa, Mehrtens JM (1987). ''Living Snakes of the World in Color''. New York: Sterling Publishers. 480 pp. . Calabar boa, more.'' The Calabar python (''Calabaria reinhardtii'') is a species of non-venomous snake in the family Boidae. The species is endemic to West and Central Africa. It is the only species in its genus. Etymology The specific name or epithet, ''reinhardtii'', is dedicated to Danish herpetologist Johannes Theodor Reinhardt (1816–1882). Taxonomy Although Schlegel (1848) first assigned this taxon to the genus ''Eryx'', most herpetologists have since regarded it as a python, which is still reflected in many of its common names. Kluge (1993) referred it to ''Charina'' (Erycinae) based on a phylogenetic analysis. ''Charina'' was used to group together '' C. bottae'' and '' C. trivirgata'' with ''C. reinhardtii'' to emphasize evidence for an historical connection between the New and Old Worlds, as well as for taxono ...
