- The snake’s Sinhala name, “Ahaetulla,” or “eye-plucker,” comes from a folk belief that the snake can pluck out human eyes, though this is a myth.
- The Ahaetulla is the only known snake species with horizontally elongated pupils, which gives it binocular vision and excellent depth perception, crucial for its arboreal lifestyle.
- It is known for its ability to sway slowly, mimicking a vine or tree branch, to camouflage itself from predators and to ambush prey.
- While it is a rear-fanged and technically venomous snake, its venom is not considered dangerous to humans.
