Ocean world

Ocean World is a special world that lives in water. It's made up of salty oceans, seas, bays, lakes and rivers. In these bodies of water live many different kinds of animals and plants. Some animals and plants like to stay close to the shore of the ocean, while others like to stay out in the deep parts. There is even a world under the ocean, called the underwater world. It is filled with corals and fish, and lots of other sea creatures like dolphins and whales. There are also creatures like octopus and crabs. The ocean is a very big place and there is so much to explore and learn about.
