Python sebae

Very large custom-built enclosure/terrarium, sturdy, heated and fully secured (lockable closures). A standard commercial vivarium is inadequate for an adult.

Minimum dimensions for an adult; larger is always better. Provide sturdy hides on both sides of the thermal gradient and a large water tub. CAUTION: a species potentially dangerous to humans and often subject to local regulations (keeping of dangerous animals, declaration/permit). Python sebae is listed on CITES Appendix II (EU Annex B): check legal obligations before any acquisition.

Moderate humidity (savanna). Aim for 50-60% ambient, with occasional peaks toward 70% and a humid hide during sheds. Excessively high, stagnant humidity promotes dermatitis and respiratory infections; ensure good ventilation.

Choose a substrate that maintains moderate humidity without staying soaked. Remove droppings and soiled areas immediately. For large adults, paper makes cleaning and health monitoring easier.

Not strictly essential (nocturnal/crepuscular species), but low to moderate UVB (Ferguson zone 1-2, UV index ~1-2) is beneficial for metabolism and well-being. Provide a regular day/night photoperiod (12h). Lamp shielded and out of direct reach.

Large, heavy and sturdy water tub, big enough to let the snake submerge fully (a semi-aquatic species and good swimmer). Clean water changed regularly; the tub also serves as a hydration area during sheds.

Sub-Saharan Africa (West, Central and East Africa). Savannas, grasslands, open woodland and scrubland, almost always near permanent water sources.

Carnivore (mainly mammals) — Rodents, then prey of increasing size according to the snake (rats, rabbits, chickens, guinea pigs). Thawed prey recommended.

An opportunistic and powerful predator; in the wild it eats antelopes, warthogs, primates, large birds and sometimes crocodiles. In captivity, use prey with a diameter close to the widest part of the body. Space out meals (adults: every 2-4 weeks or more) to avoid obesity; ban power feeding. Feed a large specimen safely, ideally with two people, using a hook and a clear separation of feeding from handling.

Clutch 20–100 eggs/young. Massive clutches, often 20 to 50 eggs, up to ~100 in very large females. The female coils around and broods the clutch; incubation ~28-32°C for about 80-90 days. Breeding is not advised outside specialized facilities given the size and temperament of the species.

• Respiratory infections (environment too cold, too humid or poorly ventilated)
• Mite infestation (Ophionyssus natricis)
• Dermatitis / scale rot linked to a wet or soiled substrate
• Stomatitis (mouth rot)
• Obesity and digestive problems from overfeeding; thermal burns on unshielded heat sources
