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 ...
Boidae 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).
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.

Poaching of pythons is a lucrative business with the global python skin trade being an estimated US$1 billion as of 2012. [18] Pythons are poached for their meat, mostly consumed locally as bushmeat and their skin, which is sent to Europe and North America for manufacture of accessories like bags, belts and shoes.

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 ...
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.
It takes a lot to give professional snake wranglers the creeps, but it happened when a group of hunters captured a python plagued by blood-sucking ticks in Florida’s Everglades.
Madtsoiidae was first classified as a subfamily of Boidae, Madtsoiinae, in Hoffstetter (1961). Further study and new finds allowed ranking the group as a distinct family in Linnaean systems . With the recent use of cladistics to unravel phylogeny , various analyses have posited Madtsoiidae as a likely clade within Serpentes , or possible ...
