On the night of the full moon, who is doing shameful things?

The symbiotic tide of the bright moon at sea means to marine animals that the world's largest beige coral reef of Moore, the Great Barrier Reef, is releasing germ cells.

The full moon is a symbol of beauty and reunion for human beings. For some animals, the full moon marks the world's largest sizing event. The Great Barrier Reef, the largest coral reef in the world, is home to more than 100 species of coral. Corals are built from animals called "polyps". Apart from humans, coral polyps are the only animals that can build structures (coral reefs) that can be seen in space. The Great Barrier Reef off the east coast of Queensland is the largest coral reef in the world.

Countless coral polyps released male and female germ cells, and hundreds of millions of small pink particles were sprayed into the sea water, like a blizzard on the bottom of the water, and the sea water was dyed pink. On Keeper Reef on the Great Barrier Reef, polyps release male and female germ cells from their body cavities.

When female and male cells of the same species meet, the coral is fertilized, producing new larvae, which then develop into the next generation of coral polyps. When these little pink particles are fertilized, they become a new generation of coral.

PHOTOGRAPH BY DAVID DOUBILET, NAT GEO IMAGE COLLECTION Corals contain proteins that detect light and are particularly sensitive to the blue wavelengths characteristic of moonlight, which makes them, like Saiyans, wild when the moon is full.

And the number of germ cells is so large that they will not be eaten up by fish and shrimp. These cells are rich in fat, so the full moon is not only a feast for corals, but also a feast for all kinds of animals.

However, due to climate change, coral reefs are rapidly disappearing. Without action to curb global warming, coral reefs could become extinct within 30 years, according to a United Nations report. Algae in coral reefs are dying from climate change, turning colorful corals white, a process known as coral bleaching. The picture is a comparison of the bleached coral and its previous healthy appearance. If the algae can't come back, the polyps die.

If the greatest insemination in the world disappears, we will lose a miracle of life. Scientists examine coral germ cells in frozen storage. PHOTO: GARY CRANITCH, QUEENSLAND MUSEUM
