The Green Pit Viper is a striking and highly venomous snake endemic to Sri Lanka. Known for its bright green coloration, triangular head, and heat-sensing pits, this species is a master of camouflage within forest vegetation. Its slow, deliberate movements and ambush hunting strategy make it a fascinating yet dangerous predator in the island’s rainforest ecosystems.
🌎 Habitat & Distribution
🌳 Habitat
The Green Pit Viper inhabits tropical rainforests, forest edges, and dense vegetation near streams and shaded areas. It is commonly found resting on low branches, shrubs, or within thick foliage.
📍 Distribution
In Sri Lanka, it is mainly found in wet zone forests such as Sinharaja, Kanneliya, and other lowland rainforests. It is especially associated with humid environments rich in vegetation.
🐍 Behavior
Feeding Behavior
This species is primarily nocturnal and feeds on small mammals, birds, frogs, and lizards. It uses an ambush strategy, relying on its camouflage and heat-sensing ability to detect prey before striking with precision.
Movement & Defense
The Green Pit Viper is slow-moving and non-aggressive unless provoked. When threatened, it may coil and strike defensively. Its venom is potent and used both for subduing prey and defense.
Social Behavior
It is generally solitary and spends most of its time resting motionless in vegetation.
⚠ Conservation Status
The Green Pit Viper is classified as Least Concern, but habitat loss and human-wildlife conflict can impact local populations. Awareness and habitat conservation are important for coexistence.
