The Enouement of the Vampire

The vampire bat have small ears and a short tail membrane. Their front teeth are shark and their primary diet are the blood of other animals. Some of these species live in the Amazon rainforest. However due to climate change, I predict within a thousand year the Amazon will become a mountainous desert with scarce sources of water. Along with this, I believe the bat will evolve to be more deadlier and more adaptable in its diet. The bat will be able to move at night or day. The animal's fur coat would camouflage in its environment to hide from predators and ensnare its prey at the right moment. It will develop a tail with quills that contain paralytic poison to stop a preys or predators movement. They will have two set of wings to enhance their flight, develop tougher skin and bones, sharper teeth, whiskers, and enhanced hearing.
