What is an ocean like?
Bubbles rise. Before your eyes is a world of colour and beauty. There are colourful fish, corals, and other forms of ocean life. Its coral reefs can be millions of years old. It is the earth's largest environment.
The ocean is a large body of salt water. The earth has five oceans that are all connected. They cover more than 360 million square kilometres, or about seven-tenths of the earth's surface. The Pacific Ocean is the largest. Millions of living things are found in the earth's oceans. Almost all forms of ocean life live in shallow(浅的) waters that are 100 metres deep or less. Yet, most of the world's oceans can be as deep as 1,500 metres or more. The
bottom(底,底部) of the ocean is too cold and dark to support much life.
Of all the animals in the ocean, the number of fish is the largest. Ocean animals have their own ways that help them live in their environment.
The ocean is a wild place. Animals live in a changing environment. Some small fish feed on plants, and large fish eat smaller fish. Much larger animals, such as sharks,
rule the underwater animal world. So how do animals stay safe in this environment?
Some fish have special tails. Waving their bodies, they can swim quickly along the ocean floor. If a stingray(魔鬼鱼) senses danger, in just a few seconds, it will cover itself with some sand. Its skin is the same colour as the sand. This camouflage is a way that the stingray and some other ocean animals use to stay safe under the water.
