Habitat of the Green Anaconda

The Green Anaconda lives in humid swamps and along river. They spend a fraction of their time in the water. They kill their prey (mainly Capy Baras) by constricting them. I believe that the Amazon will flood, and the Green Anaconda will adapt by turning into Muddy Anaconda. Like its ancestors, the Muddy Anaconda will be camaflouged but they would be brown to match the muddy sediment-filled bottom after the forest flooded. Additionally, it would be warm-blooded to stay warm in the water. Also, they would exchange most of their sight into smell and hearing so they could perceive the water. They would sense prey, and lunge. They wouldn't have gills because in an oxygen-low environment, gills make them sluggish.
