size: 4 miles first seen: 1915 The whirlpool was first seen in 1915, a few hours before the Lusitania sunk. The whirlpool's jaws sliced through the Lusitania's hull, some historians say it was another ship, however the ship that did hit it was aiming for the monster. The whirlpool has also been sighted near the sea floor in 2008. A few days after, a ton of large planes was dropped into the ocean to see how it reacted. The whirlpool catapulted itself into it and slammed its jaws shut, tearing the plane in half. The whirlpool is very aggressive, it will sometimes snap at small boats and even islands. it is unknown if it uses its claws to attack.
