Where did the Scylla from Sicily live?

The Scylla from Sicily is a mythical sea monster from Greek mythology, often described as a creature with multiple dog heads and a serpent-like body. She was said to inhabit a narrow strait opposite the whirlpool Charybdis, near the shores of Sicily, specifically around the area of the Strait of Messina. In the tales, sailors would have to navigate this perilous region, facing both Scylla and Charybdis as they attempted to pass safely.
