THE TWILIGHT ZONE
The Twilight Zone begins at 600 feet and goes as far down as 3,300 feet deep! This zone is not as bright as the Sunlit Zone, but there is still some light that can be seen. There are no plants in the Twilight Zone because there is very little sunlight. The animals that can be found in this zone are jellyfish, octopuses, squids, and whales. Many animals in the Twilight Zone have large eyes so they can see in the dark water. The water begins to turn cold because the sun is farther away.
