The '''ball python''' ('''''Python regius'''''), also called the '''royal python''', is a [[Python (genus)|python]] species native to [[West Africa|West]] and [[Central Africa]], where it lives in [[grassland]]s, shrublands and open forests. This [[nonvenomous]] [[Constriction|constrictor]] is the smallest of the African pythons, growing to a maximum length of {{cvt|182|cm}}.<ref name=McD99>{{cite book |author1=McDiarmid, R.

== Taxonomy ==
''
The [[Genus (biology)|generic]] name ''Python'' was proposed by [[François Marie Daudin]] in 1803 for non-venomous flecked snakes.<ref>{{cite book |last1=Daudin |first1=F. M. |year=1803 |title=Histoire naturelle, générale et particulière, des reptiles |volume=Tome 8 |___location=Paris |publisher=De l'Imprimerie de F. Dufart |page=384 |chapter=''Python'' |chapter-url=https://archive.org/details/histoirenaturel181802daud/page/384}}</ref> Between 1830 and 1849, several generic names were proposed for the same [[zoological specimen]] described by Shaw, including ''Enygrus'' by [[Johann Georg Wagler]], ''Cenchris'' and ''Hertulia'' by [[John Edward Gray]]. Gray also described four specimens that were collected in Gambia and were preserved in spirits and fluid.<ref>{{cite book |last1=Gray |first1=J.

==Distribution and habitat==
The ball python is native to west [[Sub Saharan Africa]] from [[Senegal]] through [[Cameroon]] to [[Sudan]] and [[Uganda]].<ref name=iucn/>
It prefers [[Grassland|grasslands]], [[savannas]], and sparsely wooded areas.<ref name="Meh87"/>
==Behavior and ecology==
Ball pythons are typically [[Nocturnality|nocturnal]] or [[Crepuscular animal|crepuscular]], meaning that they are active during dusk, dawn, and/or nighttime.<ref name="Luiselli and Angelici 1998" /> This species is known for its defense strategy that involves coiling into a tight ball when threatened, with its head and neck tucked away in the middle. This defense behavior is typically employed in lieu of biting, which makes this species easy for humans to handle and has contributed to their popularity as a pet.<ref name="Meh87"/>
In the wild, ball pythons favor mammal burrows and other underground hiding places, where they also [[Aestivation|aestivate]]. Males tend to display more semi-arboreal behaviors, whilst females tend towards terrestrial behaviors.<ref name="Luiselli and Angelici 1998" />
===Diet===
The diet of the ball python in the wild consists mostly of [[Small mammal|small mammals]] and birds. Young ball pythons of less than {{cvt|70|cm}} prey foremost on small birds. Ball pythons longer than {{cvt|100|cm}} prey foremost on small mammals. Males prey more frequently on birds, and females more frequently on mammals.<ref name="Luiselli and Angelici 1998">{{cite journal |last1=Luiselli |first1=L. |last2=Angelici |first2=F.

==In culture==
The ball python is particularly revered by the [[Igbo people]] in southeastern [[Nigeria]], who consider it symbolic of the earth, being an animal that travels so close to the ground. Even Christian Igbos treat ball pythons with great care whenever they come across one in a village or on someone's property; they either let them roam or pick them up gently and return them to a forest or field away from houses. If one is accidentally killed, many communities on Igbo land still build a coffin for the snake's remains and give it a short funeral.<ref>{{cite journal |last1=Hambly |first1=Wilfrid D. |title=Serpent worship in Africa |journal=Fieldiana Anthropology |series=Publication.
