Underwater world text

Do you know the depth of the ocean?

When the sea is rough, the bottom of the sea is still very calm. The biggest wind and waves can only affect tens of meters below the sea surface. It is difficult for sunlight to penetrate into the deep sea. The deeper the water, the darker the light, and it will be completely black below 500 meters. In this dark deep sea, there are many bright spots like twinkling stars, which are deep-water fish swimming with luminous organs.

Is there no sound at the bottom of the sea? That's not true. Animals at the bottom of the sea often whisper to each other. Listening to the audio receiver in the water can hear all kinds of sounds: some buzz like bees, some chirp like birds, some bark like puppies, and some seem to snore ... They make one sound when they eat, another sound when they travel, and give an alarm when they are in danger.

Animals in the sea have their own activities. Sea cucumber crawls by stretching its muscles and can only advance four meters per hour. There is a kind of fish, the body is like a shuttle, and it can swim dozens of kilometers per hour. When attacking other animals, it is faster than ordinary trains. Squid and octopus can suddenly spray water forward and use the reverse thrust of water to quickly retreat. There are also some shellfish that don't move by themselves, but they can travel long distances under the boat for free.

The plants on the seabed are also very different. They come in various colors, including brown, purple and red. The smallest single-celled seaweed can only be seen clearly with a microscope. The largest seaweed is 200-300 meters long and is the longest living thing on earth. The seabed is rich in coal, iron, oil and natural gas, as well as rare metals with few reserves on land.

The seabed is really a world with strange scenery and rich products.

Introduction of game plot

At noon, Atalanta, who is guarding the border between the earth and the sea, finally ushered in a rare ray of fluorescence, and everyone's face showed a relaxed look. The faint light made them feel alive.

Atlanta outpost is an outpost located at the northernmost boundary of the earth and sea. This sentry tower has a history of more than 3000 years. From the tombstones, large and small, and all kinds of broken statue nameplates under the watchtower, we can know that Atlanta once had a brilliant footprint as bright as the sun in history. However, there is nothing here except the dead silence.

Because it is close to the northernmost point, Atlanta is dark for most of the day, only in some deep gaps flashing inexplicable light. There are twelve soldiers here, except the foreman who is ill in bed and the fat man who takes care of food every day-everyone calls him that, and only ten people are left.

To put it bluntly, such an army may not even be able to resist an underage king squid, let alone guard the land and sea borders of Atlantis.

Do you know the depth of the ocean?

When the sea is rough, the bottom of the sea is still calm. So, there's no sound at the bottom of the sea? Not exactly. Animals under the sea often whisper to each other, but we just can't hear them. If you use a special underwater listening device, you can hear all kinds of sounds: some buzz like bees, some chirp like birds, some bark like dogs, and some snore like people. They make one sound when eating, another sound when traveling, and give an alarm when they are in danger.

Benthic animals have their own activity characteristics. Sea cucumber crawls by stretching its muscles and can only advance four meters per hour. Barracuda can swim thousands of meters per hour, and when attacking other animals, it is faster than ordinary trains. Squid and octopus can suddenly spray water forward and use the reverse thrust of water to quickly retreat. Some shellfish can't move by themselves, but they can travel long distances under the boat for free. There are also some deep-water fish, which have their own luminous organs and swim like twinkling stars.

There are also great differences in marine benthos. They come in various colors, including brown, purple and red. They are different in shape. Take a large family of algae as an example, from unicellular diatoms and dinoflagellates that can only be seen clearly with a microscope to giant algae hundreds of meters long, there are more than 8,000 species.

There are peaks and valleys on the seabed. It is rich in coal, iron, oil and natural gas, as well as rare metals with few reserves on land.

The seabed is really a world with strange scenery and rich products.
