As of 2017, Booidea contains 61 species, [1] 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 from New Guinea and ...
A python (top) and rattlesnake illustrating the positions of the pit organs. Arrows pointing to the pit organs are red; a black arrow points to the nostril. The ability to sense infrared thermal radiation evolved independently in three different groups of snakes, consisting of the families of Boidae (boas), Pythonidae (pythons), and the ...
The Boidae, commonly known as boas or boids, [3] 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 ...
The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes, such as the reticulated python, Burmese python, or the occasionally sympatric green anaconda, and can reach lengths from 3 to 13 ft (0.91 to 3.96 m) depending on the locality and the availability of suitable prey.

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.
Henophidia is a former superfamily of the suborder Serpentes that contains boas, pythons and numerous other less-well-known snakes. [1]Snakes once considered to belong to superfamily Henophidia include two families now considered Amerophidia (Aniliidae – red pipe snakes, and Tropidophiidae – dwarf "boas" or thunder snakes), three families now considered Uropeltoidea (Cylindrophiidae ...
[3] [4] While many species are available in the exotic pet trade, caution is needed with larger species due to potential danger. The taxonomy of pythons has evolved, and they are now more closely related to sunbeam snakes and the Mexican burrowing python. Pythons are poached for their meat and skin, leading to a billion-dollar global trade.
