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 (' ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 (three 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, or subfamily In biologi ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic gr ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants.

Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Superfamily (zoology)
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a ''taxon'') in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as ''Homo sapiens'' or '' Bufo bufo'') have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, family, order, class, phylum, kingdom, and domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the Zoological Code, the Botanical Code, the Code for Cultivated Plants, the Prokaryotic Code, and thCode for Viruses require them. However, absolute ranks are not r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

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 the classes divided 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 a ...

Calabar Python
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 taxonomic efficiency. All recent analyses, however, place ''Calabaria reinhardtii'' at the base of a large clade within Boidae, which consists of the Boinae, the Erycinae, and an Am ...
