==Description==
thumb|Close-up of head
The ball python is black, or albino and dark brown with light brown blotches on the back and sides. Its white or cream belly is scattered with black markings. It is a stocky snake with a relatively small head and smooth scales.<ref name=Meh87/> It reaches a maximum adult length of {{cvt|182|cm}}. Males typically measure eight to ten [subcaudal scales](/source/subcaudal_scales), and females typically measure two to four subcaudal scales.<ref name=Bar06>{{cite book |author=Barker, D.

Males are smaller with an average snout-to-vent length of {{cvt|111.3|cm}}, a {{cvt|43.6|mm}} long jaw, a {{cvt|8.6|cm}} long tail and a maximum weight of {{cvt|1.561|kg}}.<ref name=Aubret_al2005>{{Cite journal |author1=Aubret, F. |author2=Bonnet, X. |author3=Harris, M. |author4=Maumelat, S. |year=2005 |title=Sex Differences in Body Size and Ectoparasite Load in the Ball Python, ''Python regius'' |journal=Journal of Herpetology |volume=39 |issue=2 |pages=315–320 |doi=10.1670/111-02N |jstor=4092910 |s2cid=86230972}}</ref>

==Distribution and habitat==
The ball python is native to west [Sub Saharan Africa](/source/Sub_Saharan_Africa), from [Senegal](/source/Senegal) through [Cameroon](/source/Cameroon) to [Sudan](/source/Sudan) and [Uganda](/source/Uganda).<ref name=iucn/> It prefers [grasslands](/source/Grassland), [savannas](/source/savannas), and sparsely wooded areas.<ref name="Meh87"/>

==Behavior and ecology==
Ball pythons are typically [nocturnal](/source/Nocturnality) or [crepuscular](/source/Crepuscular_animal), 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 [aestivate](/source/Aestivation). 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 mammals](/source/Small_mammal) 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. M. |name-list-style=amp |title=Sexual size dimorphism and natural history traits are correlated with intersexual dietary divergence in royal pythons (''Python regius'') from the rainforests of southeastern Nigeria |journal=Italian Journal of Zoology |date=1998 |volume=65 |issue=2 |pages=183–185 |doi=10.1080/11250009809386744}}</ref>

===Reproduction===
thumb|Ball python eggs incubating
Females are [oviparous](/source/oviparous) and lay three to 11 rather large, leathery eggs.<ref name="Bar06"/> The eggs hatch after 55 to 60 days. Young male pythons reach sexual maturity at 11–18 months, and females at 20–36 months. Age is only one factor in determining sexual maturity and the ability to breed; weight is the second factor. Males breed at {{cvt|600|g}} or more, but in captivity are often not bred until they are {{cvt|800|g}}, although in captivity, some males have been known to begin breeding at {{cvt|300-400|g}}. Females breed in the wild at weights as low as {{cvt|800|g}} though {{cvt|1200|g}} or more in weight is most common; in captivity, breeders generally wait until they are no less than {{cvt|1500|g}}. Parental care of the eggs ends once they hatch, and the female leaves the offspring to fend for themselves.<ref name=McCurley/>

===Health and disease===
Several infectious agents and husbandry-related conditions are known to affect ball pythons, especially in captive collections. [Respiratory disease](/source/Respiratory_disease) associated with novel reptile [nidoviruses](/source/Nidovirus) (sometimes called [serpentoviruses](/source/serpentoviruses)) has been reported repeatedly in captive ball pythons and other [python](/source/Pythonidae) species; experimental infection studies and outbreak investigations provide strong evidence that these nidoviruses can cause proliferative interstitial pneumonia and fatal respiratory disease in ball pythons. Surveillance and diagnostic studies and reviews summarize nidoviruses as an important emerging pathogen in pythons. Clinical signs commonly reported include increased respiratory effort, open-mouth breathing, nasal/ocular discharge, and anorexia and weight loss. Mortality can be high in affected collections.<ref>{{cite journal |last1=Hoon-Hanks |first1=L. L. |last2=Layton |first2=M. L. |last3=Ossiboff |first3=R. J. |title=Respiratory disease in ball pythons (''Python regius'') experimentally infected with ball python nidovirus |journal=Virology |year=2018 |volume=517 |pages=77–87 |doi=10.1016/j.virol.2017.12.008 |pmid=29329683|doi-access=free }}</ref><ref>{{cite journal |last1=Uccellini |first1=L. |last2=Ossiboff |first2=R.

Other viral agents (such as [ferlavirus](/source/ferlavirus)), bacterial, and [parasitic infections](/source/parasitic_infections) also contribute to [disease](/source/disease) in [captive animals](/source/Captive_animal). Poor transport, overcrowding, and inadequate [biosecurity](/source/biosecurity) in trade and ranching operations have been implicated in increased disease risk and mortality. Good husbandry, quarantine, diagnostic testing, and veterinary oversight reduce disease transmission in collections and trade.<ref>{{cite journal |last1=Blahak |first1=S. |title=Investigations into the presence of nidoviruses in pythons |journal=Virology Journal |year=2020 |volume=17 |article-number=6 |doi=10.1186/s12985-020-1279-5 |doi-access=free |pmc=6969405 }}</ref><ref>{{cite journal |last1=Rizzo |first1=J.M. |year=2014 |title=Captive care and husbandry of ball pythons (''Python regius'') |journal=Journal of Herpetological Medicine and Surgery |volume=24 |issue=1 |pages=48–52 |doi=10.5818/1529-9651-24.1.48}}</ref>

== Threats ==
The ball python is listed as [Near Threatened](/source/Near_Threatened) on the [IUCN Red List](/source/IUCN_Red_List); it experiences a high level of exploitation and the population is believed to be in decline in most of West Africa.<ref name=iucn/> The ball python is primarily threatened by [poaching](/source/poaching) for the international exotic [pet trade](/source/pet_trade). It is also hunted for its skin, meat and use in [traditional medicine](/source/traditional_medicine). Other threats include habitat loss as a result of intensified agriculture and pesticide use.<ref name=iucn/> Rural hunters in Togo collect gravid females and egg clutches, which they sell to snake ranches. In 2019 alone, 58 interviewed hunters had collected 3,000 live ball pythons and 5,000 eggs.<ref>{{cite journal |last1=D'Cruze |first1=N. |last2=Harrington |first2=L.A. |last3=Assou |first3=D. |last4=Ronfot |first4=De. |last5=Macdonald |first5=D.W. |last6=Segniagbeto |first6=G.H. |last7=Auliya |first7=M. |title=Searching for snakes: ball python hunting in southern Togo, West Africa |journal=Nature Conservation |date=2020 |volume=38 |pages=13–36 |doi=10.3897/natureconservation.38.47864 |doi-access=free}}</ref>

==In culture==
The ball python is particularly revered by the [Igbo people](/source/Igbo_people) in southeastern [Nigeria](/source/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.
