Amazing anacondas

Most anacondas live in rainforests. They live in South American countries, like Colombia, and Brazil. These are the heaviest snakes in the world! They can grow up to 154 pounds and 17 feet long. Their diet is birds, mammals, amphibians, and reptiles. Anacondas spend most of their lives in water. They hunt in the early evenings. These snakes can live up to 30 years. I think the rainforest will turn into a savanna. The savanna has tall grass so it will be better if anacondas have legs so they can run faster. Anacondas will get shorter and use the savanna grasses as camouflage and hunting advantage. I believe they'll get sticky bellies so they can stick to their prey to catch their dinner. They will grow venomous fangs, and spikes from their backs to tails to help them hunt and protect them from predators because there are vicious animals.
