Manatees are also called "mermaids". The origin of this title can be traced back to centuries ago, when the American continent was just discovered, and European countries sent ships to America for exploration and treasure hunting. Whenever dusk falls, or the bright moon is high, explorers and sailors wandering in the sea often see some beautiful "women" swimming and playing at sea through the diffuse water mist, and some hold "babies" on their chests to nurse. The lower parts of these "women" are like fish. Sometimes they appear, and sometimes they are covered by fog at sea. Therefore, the legend of "Mermaid" was born. In fact, they saw a female manatee. The female manatee's breasts are plump and towering, as big as a human fist, and she also has a pair of nipples of 4 to 5 cm. When nursing her young, she often holds her young out to sea with two large pectoral fins, so it is easy to make people feel delusional in the evening or moonlight.

The legend of mermaid, which is full of romance and widely circulated, is popular all over the world. 19 12 years, according to the story in Andersen's fairy tale "The Daughter of the Sea", the Danish sculptor Edward Eriksson carved the statue of "Mermaid" out of red copper and put it on the beach of Copenhagen Harbor. This half-fish, half-human "sea girl" has become the symbol and pride of Denmark today.

In fact, manatees are ugly. As the navigator Columbus wrote in his diary 1493, "mermaid" is not as lovely as described in the fable. It has two sunken eyes, no helix, a huge nose connected with the upper lip and two closable nostrils at the top; The lower lip is restrained, and there is a sparse short mustache at the mouth. There is an arm-like forelimb on each side of the front body, and there are nails on the outside of the top, similar to an elephant. The hind limbs degenerate and the obese body gradually contracts backwards. At the end, there is a flat tail similar to a fish tail fin, which is spindle-shaped.
