Mermaid, also known as Mermaid and mackerel (ancient Chinese name), is a mysterious aquatic animal with human body and fish tail. It mostly lives in the waters of the sea. It often appears in fairy tales, myths, strange tales, fantasy novels or ancient legends, as well as historical records. It is a famous artistic image.

It is said that the mermaid is bounded by the waist. Most of them are beautiful women in the upper body and beautiful fish tails in scales in the lower body. The whole body is both attractive and easy to escape quickly. There are male and female. They have no soul and are as ruthless as the sea; Sound is usually deceptive as its appearance; One has many characteristics, such as temptation, vanity, beauty, cruel and desperate love. It can not only live underwater, but also live on dry land for a short time. In addition, due to the imagination of modern people, it can also be amphibious and even have magical ability.

Many modern films, cartoons, songs and other forms are named after it. It is generally believed that the biological prototype of mermaid is dugong or manatee. As for whether it really exists, people are also skeptical. In many countries, people have claimed that they have witnessed the appearance of mermaid, as well as the exploration, interpretation and introduction of mermaid fossils reported by various news media, unsolved mystery program forum, etc., but there is still no practical and clear evidence and proof for scientific research.

Dr. Eduardo of the United States, who participated in this work, said that from the evidence they have, the mermaid is not a legendary or fictional creature, but a creature that does exist in the world.
The media in Kuwait reported on August 24, 1980 that recently, a miracle of the Biological Park - the mermaid was discovered on the coast of the Red Sea. The mermaid is shaped like a fish in the upper body and a woman in the lower body - with two legs and ten toes like a human. Unfortunately, it was found dead.
There are also discoveries about living mermaids. In 1962, a scientist caught a little mermaid alive. British media, Chinese media and many other newspapers reported on the matter. Dr. vino grede of the Lenin Academy of Sciences of the former Soviet Union told the story: in 1962, a probe ship carrying scientists and military experts captured a child who could speak human language off the coast of Cuba. His skin was scaly, had gills, his head looked like a man and his tail looked like a fish.
The little mermaid said she came from the city of Atlantis and told researchers that millions of years ago, the Atlantis continent crossed Africa and South America and then sank to the seabed... Now the remaining people live on the seabed and live to 300 years old. Later, the little mermaid was sent to a secret research institution in the Black Sea for further research by scientists.
Other related discoveries in 1958, Dr. Lotan of the National Oceanographic Society of the United States photographed some human like underwater footprints at the bottom of the Atlantic Ocean 5 kilometers deep. In 1963, at the southeast seafloor of Puerto Rico, during the submarine exercise of the United States Navy, a strange ship was found, with a speed of 280 kilometers per hour, which could not be tracked, which was beyond the reach of modern human science and technology.
In 1968, American photographer Mooney found a monster near the bottom of the sea. Its face was like a monkey, its neck was four times longer than a person, its eyes were like a person but much larger, and its legs had a fast "propeller". In 1938, "toad man", with chicken breast, flat mouth and round head, was found on jumingda beach in Estonia, jumping into the Baltic Sea.
The existence of strange creatures on the sea floor such as "Mermaid" has changed from what people call "absurdity", "superstition" and "myth" to a serious scientific research topic.

The familiar image of mermaid comes from Lorelei, a beautiful mermaid often mentioned in German legends and poems. She often appears on the Bank of the Rhine river when the sky is dark. With her cold and beautiful appearance and sad and moving song, she confuses the passing boatman, distracts him and loses his direction, and finally sinks into the bottom of the river.
The upper body of a mermaid is human (mostly female) and the lower body is the body of a fish, which is the basic form. At that time, people were probably mistaken and regarded dugong, a mammal living in the sea, as a monster, so it was widely spread, but this statement had no factual basis. However, in art, literature or painting, it is mostly used as a metaphor symbol, which is more credible. Mermaids are mostly used to symbolize very unfortunate things, such as the mermaid in Andersen's fairy tales. In most of the literary works, the mermaid's end is very miserable and can't get happiness in the end. Incidentally, although the familiar Mermaid sculpture has only one tail fin in the lower body, in ancient Western paintings, mermaids usually have two tail fins, which is quite incredible.

It is said that the mermaid is the curse of the sea people. Their upper body was breathtaking, while their lower body was covered with cold fish tails (sometimes one, sometimes two). Coupled with the charming singing, countless sailors were led to no return (such as Miss siren). Although they live long, they still face death, and it is said that mermaids have no soul.
Many folklores mention the story of mermaids marrying humans. In most cases, the man stole the mermaid's hat or belt, or comb and mirror. When such things are properly hidden, the Mermaid will live with him. Once she finds her lost property, she will go back to the sea. Generally speaking, mermaids are very dangerous to humans. Their gifts will bring misfortune, such as causing disasters such as floods. Seeing a mermaid on the journey is a bad omen of a sunken ship. They sometimes yearn to see mortals drown. Take a famous example: Lorelei of the Rhine. Sometimes they lure young people to live underwater with them. Such stories are carved on the benches of some churches in Cornwall and England.
The Melanesians on the southwest Pacific islands also have similar myths and legends. Their mermaid is called "adaro". The upper body is human and the lower body is fish. They live in the sun and come to the earth through a rainbow. They usually hide in tornadoes on the sea. Unlike other mermaids, adala is a dangerous creature in the eyes of Melanesians. They will attack humans with flying fish, making them unconscious or even die.
