The Eyelash Viper is a venomous pit viper. She comes in an array of colours, from vibrant yellow to brown, green, red and even pink as well as combinations of these colours. Her characteristic feature is her "eyelashes", spiky protrusions that frame her eyes and nostrils. These are thought to break up her outline, providing her with camouflage as she lies in wait for small mammals, frogs, lizards or birds to venture near her. She has been known to wiggle the tip of her tail, luring prey into striking distance. Nocturnal in nature, she inhabits the treetops of tropical forests in Central and South America.
