Charybdis
The deadly whirlpool opposite Scylla, swallowing and spewing the sea.

Overview
Charybdis is the swallower of the sea on one side of the strait in Odyssey Book 12. Circe says that three times a day she gulps down the water and three times spews it out; a ship caught during the swallowing could not be rescued even by Poseidon. On the first passage Odysseus keeps toward Scylla, preserving the vessel at the cost of six men. After the cattle of Helios episode, he drifts alone back to the strait, where Charybdis swallows the raft. He clings to a fig tree overhead until the timbers reappear. She is not a monster defeated once but a predictable environmental danger that cannot be removed.
