Just when I thought that I had heard of them all....then came Voraphilia. 

"What is a "Vorarephile?"

A vorarephile is someone who has intense interest in or is sexually aroused by one creature eating another. The eating involved can be something as "soft" as a frog swallowing a fly, or as "hard" as a lion tearing its prey apart with claws and teeth. Cannibalism, animals eating each other, amoebas engulfing other microscopic creatures... it's all there, depending on the individual's interest. A vorarephile's emotional reaction to their fantasies is almost always erotic, but can vary from gentle, joyful surrender, to the adrenaline rush of panic and pain. Vorarephiles may enjoy the thrill of the hunt as either predator or prey."

You can find the website by googling 'vore'
Don't ask why I know :)
