Sea, a geographical term, is the general term for the largest body of water on Earth. The surface of the earth is separated by various continents into the vast waters connected with each other called oceans, the central part of the ocean is called oceans, the edge of the ocean is called seas, and they communicate with each other to form a unified body of water. [1-2]

The total area of the Earth's oceans is about 360 million square kilometers, about 71 percent of the Earth's surface area, and the average water depth is about 3,795 meters.The oceans contain more than 1.35 billion cubic kilometers of water, about 97 percent of the total water on Earth, but only 2 percent is available for human consumption.

The Earth's four major oceans are the Pacific, Atlantic, Indian and Arctic Oceans, most of which are bounded by land and sea floor topographic lines. Only 5% of the ocean floor has been explored, and 95% of the ocean floor is unknown. [3]

Oceans cover more than 70 percent of the Earth's surface and are a major driver of weather and climate. Even a small fluctuation in ocean temperature can cause drastic changes in weather and climate around the world. [11]

The aquatic animals and plants such as red coral, anemones and jellyfish under Yue Hongjun's lens are all endangered wild animals and plants in the ocean. They highlight their agility and nature and give people a bright aesthetic feeling. 19
