O.K. I know what you're going to say. That is a werewolf, not a vampire. The reality is that in many legends is not a very clear distinction between them. The vampire form the romanian mythology, the Moroi, for example, has many characteristics that are attributed traditionally to the werewolf. It can change in different animals associated with the night and the moon, like the bat, and yes, the wolf. I suppose the difference between a vampire and a werewolf in this case is that the vampire can do this at will, while a werewolf can't.
