The Vampire Deer

Do you see something a little strange about the deer in the picture above? If your eyes were immediately drawn to those rather vampiric fangs protruding from its mouth, then your next thought might have been that this must be some sort of freak of nature, an accident of birth.
That isn't how deers come, is it? For the Water Deer, otherwise and popularly known as the Vampire Deer the answer is in the affirmative.
