Final answer:
Most organisms living in the epipelagic zone are carnivorous predators that migrate up to feed at night.
Step-by-step explanation:
The epipelagic zone, also known as the epipelagic or euphotic zone, is the uppermost layer of the ocean, extending from the surface down to a variable depth that is typically about 200 meters (656 feet). This zone is characterized by its proximity to the ocean surface and the penetration of sunlight, allowing photosynthesis to occur.
Most organisms living in the epipelagic zone are carnivorous predators. These fishes live in water below the epipelagic zone but migrate up to it to feed at night.
