Description de l'espèce
Geographical Origin and Habitat: Atheris katangensis is endemic to the Democratic Republic of the Congo, restricted to the Katanga Province and Upemba National Park. It inhabits high-altitude gallery forests, montane woodlands, and thickets along river gorges, typically at elevations of 1,200 to 1,800 meters.
Taxonomy and Genetics: Belonging to the family Viperidae and the genus Atheris. Geographically isolated on the Katanga Plateau, its evolutionary path has resulted in a distinct genetic profile. It is recognized by unique scale characteristics and its highly restricted range. No subspecies are recognized.
Behavior and Habits: Nocturnal and arboreal. It hunts as an ambush predator in low shrubs and grasses near water, feeding on frogs and small mammals. It is generally a calm snake that relies on crypsis for defense. Its venom is hemotoxic and dangerous. Its prehensile tail is used to anchor itself on reeds.
Morphology: Adults typically measure 40-50 cm in length. The head is flat, triangular, and covered with small, keeled scales. The body is relatively robust for its size. The base coloration is olive-green or yellowish-green, often with purplish-grey, yellow, or brown markings forming geometric patterns.
Soins, reproduction et cohabitation
Terrarium Setup: A vertical terrarium measuring at least 50x40x60 cm with a secure locking system is necessary. Furnish the enclosure with climbing branches, vines, and dense foliage (live plants are preferred). Use a moisture-retaining substrate such as peat moss or coco coir to support humidity levels.
Lighting and Heating: Daytime temperatures should range from 22°C to 25°C, with a localized basking spot of 28°C using a protected overhead heat source. Nighttime temperatures should drop to 16-18°C. Provide a low-output UVB light (2.0 to 5.0) on a 10-hour daily cycle for overall health.
Humidity and Hydration: Maintain high humidity levels of 70-80%. Spray the enclosure daily with clean water. These snakes rarely drink from bowls and prefer to lick water droplets off leaves. Installing an automated misting or drip system is highly recommended. Ensure the enclosure has good ventilation.
Feeding and Supplementation: Carnivorous. Offer small frozen-thawed pinky mice using long feeding forceps. Neonates can be challenging to feed and may require small frogs or geckos to stimulate feeding. Dust prey items with calcium and D3 supplements once a month for adults.
Compatibility: Strictly solitary. Do not cohabitate. The high toxicity of their venom makes them hazardous to keep. Enclosures must be locked and labeled. Use proper snake hooks and handling tools for maintenance. Under no circumstances should this species be handled by hand.
Health and Common Diseases: Highly susceptible to stress from excessive movement or handling. Respiratory infections can occur in stagnant, damp environments. Dehydration is a key risk for neonates. Ensure access to an experienced veterinarian specializing in venomous reptiles.

Profil de reptile
- Régime alimentaire
- Carnivore
- These vipers are ambush predators that feed mainly on small mammals, frogs, and lizards in the wild. In captivity, they can usually be transitioned to a diet of appropriately sized rodents, such as mice or small rats. Feeding should occur every one to two weeks depending on the age and size of the snake.
- Taille adulte
- 50 cm
- Mode de vie/microhabitat
- Arboreal
- Arboreal species spend the majority of their lives in trees and shrubs, requiring vertically oriented enclosures with climbing branches. Terrestrial species need ample floor space with hiding spots among the leaf litter. Both require specific temperature and humidity gradients to thrive.
- Cycle d'activité
- Nocturnal
- These snakes are primarily nocturnal or crepuscular, becoming most active during the evening and night. During the day, they often rest coiled on branches or concealed in vegetation. Their activity levels can increase significantly after a period of rain or during the breeding season.
- Sociabilité
- Solitary
- They are typically ambush hunters, relying on their camouflage to remain undetected by both prey and predators. When threatened, they may adopt a defensive posture, hiss, or strike rapidly. They are generally not aggressive but will defend themselves fiercely if provoked.
- Reproduction
- Viviparous
- Most of these species are viviparous, giving birth to live young after a gestation period of several months. The neonates are fully independent and venomous from birth. Breeding often requires a cooling period or specific environmental cues to simulate natural seasonal changes.
- Tolérance aux manipulations
- Display only
- Handling must be strictly avoided except when absolutely necessary for husbandry or medical reasons. Always use appropriate tools such as snake hooks or tongs to move the animal safely. These are highly venomous species, and a bite can result in severe medical consequences.
- Brumation
- Non requise
- Depending on their natural range, some may undergo a mild winter cooling period to stimulate breeding. This is not a deep brumation but rather a slight drop in temperature accompanied by reduced feeding. Tropical species may not require any significant seasonal changes in captivity.
- Mue
- Periodic
- Shedding occurs periodically as the snake grows, heralded by the eyes turning a milky blue color. During this time, they should be left undisturbed and humidity should be slightly increased to facilitate a clean shed. A healthy snake will shed its skin in one complete, unbroken piece.
