What was the whirlpool that that sanked Odysseus ship?

The whirlpool that sank Odysseus's ship is known as Charybdis. In Homer's "Odyssey," it is described as a massive whirlpool located opposite the sea monster Scylla, creating a treacherous passage for Odysseus and his crew. Charybdis would swallow the sea three times a day, creating a dangerous vortex that could engulf ships. Odysseus had to navigate carefully between these two perilous threats on his journey home.
