Blood Thirst!!


For those of you who have read the Twilight Series, or are reading it, you know that blood plays a focal point of the plot. For those of you who haven't read and/or don't want to, its about vampires. Vampires use blood as their food source to survive. While vampires are a creation of fiction, sometimes fact is even stranger. There are a variety of animals that feed on other animals' blood. Mosquitoes, fleas, ticks, leeches, bed bugs, and vampire bats are just a few. There's even a vampire finch that drinks the blood of other birds.


Do some research of your own about one of these animals or another type of sanguivore (blood eaters.) Write a short paragraph (5-6 sentences) about what you learned about them. Please no paragraphs on human vampires!
