Green Anaconda

This anaconda is rather cumbersome on land, but stealthy and sleek when in the water. Since this snake does spend most of its time in the water, its eyes and nostrils are located high on its head, thus allowing the anaconda to see and breathe as it lays in wait for its next meal.

Green Anaconda

Eunectes murinus

Habitat: South America, east of the Andes Mountains. Prefers swamps, marshes and slow-moving streams/rivers.

Diet in the wild: Variety of prey including turtles, caiman, birds, and many mammals including deer and capybara, even jaguar from time to time

Size: 20 feet long; 200+ pounds; diameter of 12 inches. Females are usually larger than males. This is the heaviest and longest snake species (there are some reports of individual reticulated pythons surpassing anaconda size). There are reliable reports of 30 foot anacondas weighing over 400 pounds.
