8) Vampires only need to feed twice a month to be in control of their thirst. 9) Vampire eyes change based on how much blood they have consumed recently. Black: Thirsty. Red: Well-fed on human blood. Gold: Well-fed on animal blood. As they become thirstier, the color fades to black. 10) Vampires have circles under their eyes that get darker as they get thirstier. When they are well fed, the circles are almost erased. 11) Vampires are invulnerable to traditional methods of killing them such as garlic, crosses, holy water, stakes, etc. 12) Some vampires have supernatural abilities; Edward reads minds, Alice sees the future, and Jasper controls emotional climates. 13) Vampires dress in light colors to deemphasize their pallor. 14) Vampires do not eat human food -- if they do, it must be vomited up later. less
