Growing over 30 feet (9 meters) long and weighing over 500 pounds (227 kilograms), the green anaconda is the world’s largest snake and it lurks in the Amazon River, lying in wait for prey. Because of its size, the green anaconda is awkward on land, but in the water it can move stealthily and quickly, striking at anything it knows it can overpower jaguars,caimans, wild pigs, deer and even humans, especially children. It coils its body around its prey and drags it into the water, suffocating it within minutes, and then swallows it whole with its large jaws.
