I was on a site that was about all different types of monster, mythical creatures, marvelous animals, etc. n i noticed a creature called the "Scylla". Well that is rather similar to "Skylla". soooo i checked it out n here's wat it said: A sea-monster that guards one side of the straits of Messina. Scylla had six heads, and around
her waist is a ring of barking dogs. She seizes sailors as they pass through the strait. Originally she was a beautiful nymph who was transformed by the sorceress Circe out of jealousy. She did this by filling the sea where Scylla was bathing with terrible serpents and by enchantment, they became part of her body. Well, it also featured a picture:

well, could there be some sort of similarity??? YOU DECIDE! well, it is a HER...n it is UGLY...n the picture depicts the extra head on TENTACLES. go figure!
