Scylla was a beautiful water nymph, but Amphitrite due to jealousy (some myths claim it was the sorceress Circe) changed her into a monster with six heads for she broke the heart of a man. She picks off sailors from ships and eats them. NOTICE: dont believe this page because obviously anyone can change it!! OK
Across from Scylla, Charybdis is located. Charybdis was known for swallowing high quantities of water, and then vomiting the water back out. This would cause whirpools that would drown ships, no matter what size. Some myths claimed she was simply a large whirpool. A later myth claimed that she was actually a daughter of Poseidon and Gaea. This myth also claimed she aided her father against his feud with Zeus, helping him by mainly swallowing up islands and land. Zeus, angry because of the land she stole, turned her into what she is now, and gave her a limitless thirst for the sea. Her constant drainage of the sea was known to cause whirpools.
