Vampire bats have sharp, elongated incisors specialized for making small, precise incisions through which they can access blood vessels. Vampire bats don't exactly suck blood instead they drink blood using the physics of capillary action where a liquid can move through a narrow tube or cylindrical space often against the downward of gravity. They have special grooves on their tongue which with their lower lip and incisors can create a tube like shape that easily whisk up the liquid.
