Final answer:
The Nautilus moves through the Bathypelagic and Mesopelagic zones to find more prey.
Step-by-step explanation:
The Nautilus are moving through the Bathypelagic and Mesopelagic zones in order to find more prey. The Bathypelagic zone is the area of the ocean between 1,000 and 4,000 meters deep, while the Mesopelagic zone is between 200 and 1,000 meters deep. These zones are rich in food sources, including small fish, shrimp, and jellyfish, which attract the Nautilus. By migrating from deeper areas to shallower areas, the Nautilus can access a larger food supply and increase their chances of survival.
