Species description

Black Eyed Leucistic:: The homozygous version of the Fire complex. Also an immaculate white snake, but unlike the BEL, it possesses solid ink-black eyes.
Geographical Origin and Habitat: Inhabits the scorching grasslands, scrub savannas, and forest edges of sub-Saharan Africa (Ghana, Togo, Benin). They are strictly terrestrial and fossorial creatures: in nature, they spend most of the day and year buried inside deep abandoned rodent burrows or termite mounds, coming out only in the dead of night.
Taxonomy and Genetics: Pythonidae family. The Ball Python is the undisputed 'King' of genetics in the reptile hobby. There are over 7,000 documented morphs, from solid colorations like the 'Super Black Pastel' and 'Blue-Eyed Leucistic', to complex genetic patterns like the infamous 'Spider' (which unfortunately carries an incurable neurological defect called 'wobble', causing the snake to lose equilibrium and spin its head).
Behavior and Habits: They are, static, and extremely fearful snakes. Their defense is almost never biting (they are incredibly mild), but rather the famous defensive posture from which their English name derives: if touched suddenly, they curl up into a dense, tight muscular sphere, hiding their delicate head in the center of the coils. They explore the tank clumsily and heavily. They are pure ambush predators.
Morphology: Medium-sized but very chunky snakes, shaped like a massive 'sausage'. They rarely exceed 4.5-5 feet (150 cm) but can weigh several pounds. Their head is small, distinct from the neck, equipped with heat-sensing pits visible on the upper and lower 'lips' - literal infrared organs to detect the body heat of mice in total darkness. Females are significantly larger, thicker, and heavier than the slender males.

Care, breeding and tankmates

Terrarium Setup: Hating open spaces, Ball Pythons stress to death in immense, barren terrariums. A low, wide tank (40-gallon breeder, 36x18x18 inches) is ideal, but it MUST be cluttered with dense fake vegetation to block their line of sight. Tall branches are mostly ignored due to their bulk; they love the ground. The VITAL requirement for their mental health is having two EXTREMELY TIGHT and dark hides (one on the hot side, one on the cool side) that physically press against all sides of their coiled ball: if the hide is too roomy, they won't feel safe.
Lighting and Heating: Ruthless African heat. They require very high temperatures to digest massive whole prey: the hot side/basking spot must reach 90-93°F (32-34°C), while the cool side should sit at 78-80°F (25-26°C). An UNDER-TANK HEATER (UTH) connected to a THERMOSTAT is preferred by most breeders because the snake sits constantly on the ground, although a shielded overhead ceramic heat emitter guarantees better ambient warmth needed to stave off pneumonia.
Humidity and Hydration: They require medium-high humidity (55-70%) to ensure perfect sheds. Humidity must be bumped to 80% during the shedding days (milky eyes). If humidity is too low (<50%), their eyes and skin will dry out, peeling off in painful, jagged fragments (retained shed / stuck eye caps). Use a substrate that holds moisture well, like cypress mulch or coco husk, NEVER sand or pine/cedar wood shavings.
Feeding and Supplementation: THE CURSE OF BALL PYTHONS. They are infamous for their prolonged, unexplained 'hunger strikes'. A python stressed by handling, the wrong enclosure, cold drafts, or the approaching winter season can stop eating for 6 consecutive months without losing much weight. They are extremely 'picky': they will devour mice or small rats only if offered thawed in hot water (being infrared predators, if the rodent is cold to the touch, they will completely ignore it). Feed adults every 15-20 days.
Compatibility: Strictly solitary. Placing two specimens in the same tank is mental torture for these shy animals. Due to space competition, they will tend to lay on top of each other in the hot hide, mutually causing chronic stress and triggering immediate feeding strikes.
Health and Common Diseases: Stress-induced anorexia (prolonged refusal of food) is the number one cause of owner despair, followed by severe thermal burns caused by heat mats placed inside the tank without a thermostat. Respiratory Infections (RI), caused by high humidity paired with cold temperatures (below 75°F / 24°C), literally make the snake drown in its own mucus: it will hold its mouth open trying to gasp for air, making clicking or wheezing sounds.

Reptile profile

Diet
Carnivore
In the wild, ball pythons primarily feed on small mammals like rodents, shrews, and sometimes birds. In captivity, their diet consists almost entirely of appropriately sized mice or rats offered pre-killed or frozen-thawed. They are notoriously picky eaters, sometimes fasting for months during the winter or breeding season. Hatchlings begin with hopper mice or rat pups, gradually moving to adult rats as they grow.
Adult size
150 cm
The catalog's scalar value is 150 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 150 cm for this species, recorded as total length (TL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
Lifestyle/Microhabitat
They are terrestrial, heavy-bodied snakes that prefer floor space over height, originating from the grasslands and termite mounds of West Africa. They feel most secure in compact, cluttered environments with multiple tight-fitting hides and a moisture-retaining substrate like coconut husk.
Activity cycle
Ball pythons are heavily nocturnal ambush predators. During the day, they remain tightly coiled and hidden inside snug, dark hides. Activity peaks late at night when they slowly prowl their enclosures or wait motionless near hide entrances for passing rodent prey.
Sociality
Solitary
They are known for their docile nature and characteristic defense mechanism of curling tightly into a "ball" when threatened, hiding their head in the center. These snakes are mostly nocturnal or crepuscular, spending daytime hours hiding in burrows or under debris. They are ground-dwellers that move slowly and purposefully, making them excellent pets for beginners due to their low-stress handling requirements.
Reproduction
Oviparous
Ball pythons are oviparous, meaning they lay eggs to reproduce. Females typically lay a clutch of 1 to 11 eggs after a gestation period of several weeks, coiling around them to regulate temperature and humidity. The eggs incubate for roughly 60 days before hatching. Breeders of morphs carefully pair adults to produce specific genetic outcomes.
Handling tolerance
Renowned for their incredibly docile and shy nature, they rarely strike in defense. Instead, their primary defense mechanism is curling into a tight, protective ball with their head tucked inside. They are slow-moving and tolerate gentle handling very well once they feel secure.
Brumation
Ball pythons do not brumate. As tropical animals, they require a stable, warm thermal gradient (ambient 26°C / 78°F, hot spot 32°C / 90°F) year-round. Dropping temperatures can lead to severe respiratory infections and prolonged feeding strikes.
Molting
Regular
Shedding happens every 4-8 weeks. Ambient humidity should generally be kept around 55-60%, but must be boosted to 70-80% during the shedding cycle to prevent stuck sheds, particularly around the delicate eye caps and tail tip.
