There are all kinds of life forms in the oceans. Some examples are giant squid and seahorses. Some plants are so small that you would need a microscope to see them. There are also huge animals like the blue whale, the largest mammal in the world.
Scientists divide the oceans into four layers to study. Most ocean life forms are found in the Sunlight Zone. The second layer, the Twilight Zone, is colder and darker than the Sunlight Zone. Fewer plants and animals are found here. The Midnight Zone is below the Twilight Zone. Sunlight does not reach this layer and there is very little plant or animal life.
