The main content of the great revelation of marine life: This book is full of more than 80 pages, it uses concise and vivid language and colorful drawings to show me the origin of life, coastal areas, underwater treasures, cold tropical seas, deep sea areas, sea movements and other wonderful content. As soon as I got my hands on the book, I couldn't wait to finish it and read it carefully and completely.

I learned that life on Earth originated at the bottom of the ocean about 4 billion years ago. The shallow sea, close to the surface, is full of signs of life. There is a lot of treasure buried at the bottom of the sea.

In the shallow waters of the warm tropical seas, there is a lot of life. Located at the northernmost point of the planet, the Arctic Ocean is the coldest ocean in the world. The deeper the sea, the darker it becomes.

Scientists used to think that no creature could survive at such a deep seabed, until they discovered creatures that they had never seen before. The sea is in motion all the time, and the waves, tides, etc. are all forms of movement of the sea water, and I believe that all readers who have read the book firmly believe that the sea is a precious resource for human beings.

<> cute little inhabitants of the seabed. Interesting "The Secret of Life in the Sea", the heart swims in the infinite mystery of the ocean. There is a sea snake covered in colorful patterns, and it is a creature that everyone at the bottom of the sea is afraid of.

Its tail is not as sharp as that of snakes on land, and in order to adapt to the needs of life at the bottom of the sea, its tail has evolved to be flattened and live like a boat's oar. Its lungs are long, which can both store air and regulate the rise and fall of the body, so the sea snake can lurk underwater for a long time, and it can be a master swimmer. Sea snakes have these advantages, so they can live happily on the bottom of the sea.

Sea snakes have few natural predators in the sea, and even if they are as fierce as a large shark and encounter a sea snake, even if they are hungry at the time, they will never feed on them. But sea snakes are not without predators, and when they swim in the ocean in groups, the sea eagles, the sea's best flying eagles, swoop down from the sky at great speed, latching on to the sea snake and taking it off. Don't look at the sea snake rampant in the water, once it leaves the sea, it loses the ability to attack, and can only be at the mercy of the sea eagle.

"The Secret of Life in the Sea" also introduces the children to the baby turtle that can recognize the way: the mother turtle lays her eggs on the beach, and with the help of the heat of the sun's rays and the temperature of the sand, after 50 to 60 days of hatching, the baby turtle will break out of the shell. With their natural ability to recognize scents and directions, they return to the sea.
