Can you find the Eyelash Viper (Bothriechis schlegelii)? It's generally good to see them before you stumble upon them in the Central and South American rainforest, as this small pit viper has a venomous bite. The one in the photo is green, but they can take on a variety of colors (yellow, pink, brown, green), and they get their name from enlarged, upright scales around their eyes that look like eyelashes. Primarily an ambush predator, this species of snake may even return to the same spot annually during bird migrations to try and snag some avian prey.
