The common green vine snake, scientifically known as Ahaetulla nasuta, is a non-venomous species within the family Colubridae. This snake is predominantly found in South and Southeast Asia, thriving in a variety of habitats, including forests, gardens, and shrublands. Its elongated, slender body can reach lengths of up to 1.5 meters, and it is easily recognized by its vibrant green coloration, which provides excellent camouflage among foliage.

The common green vine snake is arboreal, often seen resting on branches and leaves, where it relies on its cryptic coloration to avoid detection by predators and prey alike. Its diet primarily consists of small lizards and insects, which it captures with quick strikes. Notably, this species has large, forward-facing eyes that enhance its depth perception, aiding in hunting. While generally docile, the common green vine snake may exhibit defensive behaviors if threatened, such as flattening its body or displaying a striking posture. Its role in the ecosystem as both predator and prey highlights its importance in maintaining ecological balance. Conservation of its habitats is crucial, as urbanization and habitat loss pose significant threats to its populations.
