Vampire bats now are able to detect heat signatures of things. They have been using this to find where vains are more likely to be at within animals. Scientist are studing Vampire bats right now and more related to horses than rats. Vampire bats gained this ability through evolution over time to help them survive better to get food easier, though bats that eat fruits and insects don't have this ability.
