How Did Manatees Inspire Mermaid Legends?

It’s that time of year when manatees, the slow-moving aquatic mammals of the southeast coast of North America, start to migrate south into warmer waters—and often run into trouble.

In Florida, many of the languid giants—also called sea cows—are killed each year in boating collisions.

That’s why November is also Manatee Awareness Month, which just this year became official in the state of Florida. Governor Rick Scott issued a proclamation to protect the state’s official mammal as a “distinctive, valuable, and beloved natural resource.”

The International Union for Conservation of Nature lists the American manatee—also known as the West Indian manatee—as vulnerable, with less than 10,000 individuals of that species left in the wild, according to its website. The population in Florida is estimated at 4,831, according to Save the Manatee. The manatee is a sirenian—an order of aquatic mammals that includes three species of manatees and their Pacific cousin, the dugong.

The ocean’s largest herbivore, sirenians are also notable as the creatures that have long fueled mermaid myths and legend across cultures. Below we take a look at some of the most fascinating fables.

“Their Faces Had Some Masculine Traits”

Christopher Columbus, in his first journey to the Americas, caught a glimpse of three “mermaids” off the prow of his ship, writing in his journal:

“On the previous day

[8 Jan 1493], when the Admiral went to the Rio del Oro [Haiti], he said he quite distinctly saw three mermaids, which rose well out of the sea; but they are not so beautiful as they are said to be, for their faces had some masculine traits.” (Voyages of Columbus 218).”

Indeed, manatees and dugongs are both known to rise out of the sea like the alluring sirens of Greek myth, occasionally performing “tail stands” in shallow water. (See “Severe Scurvy Struck Christopher Columbus’s Crew.”)

With forelimbs containing five sets of fingerlike bones, and neck vertebrae that allow them to turn their heads, it’s possible that manatees could be mistaken for humans from afar.

Following Columbus’s expedition to the Americas, sideshows in Europe advertised “recently discovered” mermaids from the new world, often a deceased sirenian.
