Mermaid is to the waist as the boundary, the upper half of the body is a beautiful woman, the lower half of the body is a beautiful fish tail in scales, the whole body, not only full of temptation, but also easy to escape quickly. They have no soul and are as heartless as the sea water; their voice is usually deceptive like its appearance; they have the characteristics of temptation, vanity, beauty, cruelty and despair. There are movies, cartoons, songs and so on.
The image of mermaid that people are familiar with comes from Lorelei, a beautiful mermaid often mentioned in German legends and poems. She often appears on the Bank of the Rhine when the sky is dark and unclear. With her cold and beautiful appearance and sad and moving songs, she confuses the boatman passing by, distracts them and loses direction, and finally sinks to the bottom of the river.
Some American researchers say that mermaid is not just a legend, it really exists in our real world. As soon as it came out, it immediately attracted wide attention. The researchers believe that the mermaid is in the process of the evolution of ancient apes into humans, a part of the ancient apes into the sea life, evolved into the ape, and the same ancestor as humans. It is only in the slow evolution years that human beings forget it and become a legend.
