Within a few metres of you, almost certainly, a vampire is feeding. It grabs its victim and punctures its skin, then drains its bodily fluids. The process takes just minutes.
These fascinating organisms feed much like a vampire, and can even magnify their own size in order to attack larger prey. Vampires exist in nature, and if ever there was a more interesting example of how little we know of the universe, and just how much possibility exists in the infinite laboratory of Mother Nature… this would be it.
Maybe some of us shouldn’t write off the humanoid vampire so quickly. If there are so many and widely dispersed variations of vampire behavior, should we discount them as fiction so quickly?
