A diagram of the different zones of the ocean from deepest to closest to the surface with the animals that live in them: midnight zone, twilight zone, sunlight zone
ILLUSTRATION BY STEVE SKELTON FOR TIME FOR KIDS

The ocean is deep. It is made up of different zones, or areas. Here are three of them.

Sunlight Zone

This zone gets heat from the sun. It gets light, too. Most ocean plants and animals live here. It is where people swim and dive.

Twilight Zone

This zone is cold. It does not get much light. Almost no plants grow here. Some animals that live in this zone make their own light.

Midnight Zone

This zone is the largest. It is very cold. It does not get any sunlight. The only light comes from animals that make their own.
