How Anacondas will adapt

Right now anacondas are semiaquatic hunters that rely on animals coming down to a stream to drink water and then they can pounce, their diet consists of a lot of fish and smaller reptiles as well as sometimes animals like sheep and capybaras. Unfortunately due to global warming and pollution affecting the rainforest the rivers have begun to recede and many droughts have occurred. Because of this, I believe that anacondas will become more forest floor hunters. In the second picture, the anaconda has a greener appearance and different camouflage to blend in with the dark and lush forest floor. i also believe that they will become wider and shorter to adapt to their new diet. One more thing that seems like a possible outcome is more muscles in the head because it fights with large prey, but this also means it will gain eyelids protecting its eyes from debris.
