The ocean is also home to reptiles such as turtles and sea snakes. You’ll find creatures like lobsters and crabs, too, with shells as hard as armor but no skeletons. Other sea creatures have soft bodies but no armor—octopuses can change color and squirt clouds of black ink, sea anemones look like flowers, and some starfish are covered in thorns. Oceans cover more than two-thirds of the Earth’s surface. They stretch down deeper than the tallest mountains reach to the sky. There are probably many weird sea creatures that we have not even discovered yet.
