Anacondas can move as fast as 5 miles per hour on land. In water, anacondas can keep up a speed of 10 miles per hour. When following their prey, they usually move at 8 miles per hour.
They live close to rivers, lakes, and swamps. Most of the time, they live on their own. When they are in danger, water is their main way out. They often choose to slip into the water without being seen rather than attack.
