Descrição da espécie
Geographical Origin and Habitat: Atheris acuminata is endemic to western Uganda, with a very restricted range, notably within the Kyambura Gorge. It inhabits forest-savanna mosaics, gallery forests, and dense river gorge thickets, adapting to local warm, humid microclimates with distinct dry and rainy seasons.
Taxonomy and Genetics: A member of the family Viperidae and the genus Atheris. The species name acuminata refers to the pointed, sharp shape of the scales on its head. Its genetic lineage is highly isolated, having evolved within deep Ugandan river gorges, making it a unique evolutionary unit within the genus.
Behavior and Habits: Nocturnal and arboreal. During the day, it remains motionless in dense shrubs, relying on crypsis. At night, it hunts small vertebrates from ambush positions. It possesses a potent hemotoxic venom for which there is no specific antivenom. Its prehensile tail provides stability during strikes.
Morphology: This is one of the smallest species of Atheris, with adults typically measuring less than 50 cm in total length. It has a flat, triangular head covered with elongated, pointed scales that create a fringed or crested appearance. The dorsal coloration is green to olive-green, blending with mossy bark.
Cuidado, criação e companheiros de tanque
Terrarium Setup: A vertical terrarium measuring at least 50x40x50 cm with a secure locking system is necessary. Provide fine 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 24°C to 26°C, with a localized basking spot of 29°C using a protected overhead heat source. Nighttime temperatures should drop to 18-20°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 75-85%. 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.

Perfil de réptil
- Dieta
- 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.
- Tamanho adulto
- 60 cm
- Estilo de vida/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.
- Ciclo de atividades
- 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.
- Socialidade
- 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.
- Reprodução
- 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.
- Tolerância de tratamento
- 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.
- Brumação
- Não obrigatório
- 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.
- Muda
- 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.
