I read a book about undersea life. The oceans cover 70% of Earth’s surface. In the oceans, the animals and plants survive. There are five oceans; The Arctic Ocean, Atlantic Ocean, Pacific Ocean, Indian Ocean, and, Southern Ocean. The oceans have currents, tides, and waves.

There are many animals, such as mammals, otters, whales, planktons, and sharks. The sea turtles hunt for smaller fish.  
Believe it or not corals are small animals. They have soft bodies, but they have tough outer skeletons. People are not the only one who are fishing. Birds fish, too. The oceans are very deep. It’s difficult for humans to travel safely within the deep ocean. Therefore, there isn’t much known about the deep ocean.
