The Fluorite Lake Boa

My Creature is the Boa constrictor and right now in the present it has the adaptation of camouflage to help it go undetected in the rainforest. My future creature is what the Boa Constrictor will evolve into in one million years. I predict what its habitat is going to be like is that the rainforest near sea level will flood with 20 feet of water but the trees will still be there. It will also still be dark like it is now although most of the creatures will be in the water. Some of the adaptations it will develop are gills so that it can breathe underwater. It will also develop venom so that it can kill prey more easily which will be fish and some lizards. Boa Constrictors also have a very remarkable ability to swim really well so it will help them survive in their new environment.
