The Creepiest Real-Life Mermaid Evidence
A Japanese Mermaid Has A Snake Body And Fangs

Sure, it’s unsettling to think about a half-fish person — but what about a half-snake person? This Japanese myth is known as Sure-Onna, and she has the face and hair of a woman, but the eyes and teeth of a snake.
Nure-Onna sits by the shore, cradling a bundle to trick humans into thinking she’s a distressed mother holding a baby. If a passerby picks up her bundle, it becomes so heavy it pins them to the rocks. Then, Nure-Onna uses her long, pointed tongue to drain their blood at a pace that suits her. In some versions of the tale, she even strangles her victims with her pretty hair.
The Blue Men Of The Minch Have A Taste For Human Flesh

Scottish folklore tells of a strange group of creatures that inhabit one particular strait. According to legend, they would appear in groups with only their torsos raised out of the water. These Blue Men of Minch would wave to sailors in a friendly manner, and the sailors would assume they were innocent people in need of rescue. But when the sailors got closer, they would see the unnatural blueness of the men’s skin and the elongated, twisted features of their faces.
Unfortunately, sailors close enough to recognize the Blue Men were close enough to become prey. The Blue Men would drag them into the water and feast on their flesh.
