Found from the wilds of the Amazon rainforest to the forests of Central America, green anacondas will eat mammals including deer, monkeys, and capybara, as well as birds, fish, and turtles. The anaconda may also simply hold its prey under water until drowning it. A swift bite holds their prey while several loops coil around the prey’s body, immediately restricting its breathing. Anacondas are also ambush hunters and true constrictors.
They’re excellent swimmers and known to drift in river currents as a convenient way of locomotion. Green anacondas are known as “water boas,” able to stay submerged in water for over ten minutes.
