Evolution and Systematics
The jaws of pythons allow the snakes to swallow huge prey because of their multibar linkages.
"We mammals make no great use of multibar linkages, but a lot of other vertebrates depend on them. The most famous are snakes that can swallow items of prey whose diameters and cross sections exceed those of themselves. How pythons (genus Python) manage was carefully analyzed by Frazzetta (1966), who regarded their skull and jaws as linkages with no fewer than eight bars. Such snakes use two such linkages, one on each side of the head, with a lot of flexibility in between. The setup permits the mouth to gape sufficiently to accommodate huge prey, which then get digested at leisure." (Vogel 2003:400-401)

Python, from the Greek word (πύθων/πύθωνας), is a genus of nonvenomous pythons found in Africa and Asia. Currently, 12 species are recognised. A member of this genus, P. reticulatus, is among the longest snake species and extant reptiles in the world.
Found in Africa in the tropics south of the Sahara, but not in the extreme south-western tip of southern Africa (Western Cape), or in Madagascar. In Asia, it is found from Bangladesh, Nepal, India, Pakistan, and Sri Lanka, including the Nicobar Islands, through Myanmar, east to Indochina, southern China, Hong Kong and Hainan, as well as in the Malayan region of Indonesia and the Philippines.
Some suggest that P. molurus and P. sebae have the potential to be problematic invasive species in South Florida. The United States Department of Agriculture reports that only Python molurus bivittatus is an invasive species in the United States. More recent data suggests that these pythons would not withstand winter climates north of Florida, contradicting previous research suggesting a more significant geographic potential range.

Python skin is used to make clothing such as vests, belts, boots, shoes or fashion accessories such as handbags. It may also be used to cover the sound board of some string musical instruments, such as the banhu, sanxian or the sanshin.
Many species of pythons, such as P. regius, P. brongersmai, P. bivittatus and P. reticulatus are popular to keep as pets due to their ease of care, docile temperament, and vibrant colors, with some rare mutations having been sold for several thousands of dollars. Despite controversy that has arisen from media reports, pet pythons are relatively safe to own when proper safety procedure is practiced and deaths associated with pet pythons are very isolated when compared to other domestic animals such as dogs and horses.
