A worldgorger dragon... that's what you can find when paddling with a dugout canoe through the rivers of Ecuador's Yasuni National Park. The dragon is known as the Green Anaconda (Eunectes murinus). Photo by Alejandro Arteaga
An anaconda is a large, nonvenomous snake found in tropical South America. Although the name actually applies to a group of snakes, it is often used to refer only to one species in particular, the common or green anaconda, Eunectes murinus, which is one of the largest snakes in the world.
