Fun fact:The ocean itself covers two thirds of our earth.
This is a photo of the ocean layer so as you can see there are 5 layers of the ocean. There is sunlight zone,twilight zone and more. In the sunlight zone Humans can swim there and you may not find any sea creatures there only plants such as seaweed. Next is the abyss only a few animals may live there like whales and squid. One more the next one is trench Well the trench most animals do not live there unknown animals might live down there no one knows, The trench is also called the ocean floor.
Fun fact:The midnight zone is up to 4000m below the surface of the ocean. Sunlight cannot reach this layer which means it is pitch black down there.
