With most of our blue planet covered by water, it's little wonder that, centuries ago, the oceans were believed to hide mysterious creatures including sea serpents and mermaids. Merfolk (mermaids and mermen) are, of course, the marine version of half-human, half-animal legends that have captured human imagination for ages. One source, the "Arabian Nights," described mermaids as having "moon faces and hair like a woman's but their hands and feet were in their bellies and they had tails like fishes."
C.J.S. Thompson, a former curator at the Royal College of Surgeons of England, notes in his book "The Mystery and Lore of Monsters" that "Traditions concerning creatures half-human and half-fish in form have existed for thousands of years, and the Babylonian deity Era or Oannes, the Fish-god ... is usually depicted as having a bearded head with a crown and a body like a man, but from the waist downwards he has the shape of a fish." Greek mythology contains stories of the god Triton, the merman messenger of the sea, and several modern religions including Hinduism and Candomble (an Afro-Brazilian belief) worship mermaid goddesses to this day.
Many children are perhaps most familiar with the Disney version of "The Little Mermaid," a somewhat sanitized version of a Hans Christian Andersen fairy tale first published in 1837. In some legends from Scotland and Wales mermaids befriended — and even married — humans. Meri Lao, in her book "Seduction and the Secret Power of Women," notes that "In the Shetland Islands, mermaids are stunningly beautiful women who live under the sea; their hybrid appearance is temporary, the effect being achieved by donning the skin of a fish.
They must be very careful not to lose this while wandering about on land, because without it they would be unable to return to their underwater realm."
In folklore, mermaids were often associated with misfortune and death, luring errant sailors off course and even onto rocky shoals (the terrifying mermaids in the 2011 film "Pirates of the Caribbean: On Stranger Tides" are closer to the legendary creatures than is Disney's Ariel).
Though not as well known as their comely female counterparts, there are of course mermen — and they have an equally fierce reputation for summoning storms, sinking ships and drowning sailors.
One especially feared group, the Blue Men of the Minch, are said to dwell in the Outer Hebrides off the coast of Scotland. They look like ordinary men (from the waist up anyway) with the exception of their blue-tinted skin and gray beards. Local lore claims that before laying siege to a ship, the Blue Men often challenge its captain to a rhyming contest; if the captain is quick enough of wit and agile enough of tongue he can best the Blue Men and save his sailors from a watery grave.
Japanese legends have a version of merfolk called kappa. Said to reside in Japanese lakes, coasts and rivers, these child-size water spirits appear more animal than human, with simian faces and tortoise shells on their backs. Like the Blue Men, the kappa sometimes interact with humans and challenge them to games of skill in which the penalty for losing is death. Kappa are said to have an appetite for children and those foolish enough to swim alone in remote places — but they especially prize fresh cucumbers.
'Real' mermaids?
The reality of mermaids was assumed during medieval times, when they were depicted matter-of-factly alongside known aquatic animals such as whales. Hundreds of years ago sailors and residents in coastal towns around the world told of encountering the sea maidens. One story dating back to the 1600s claimed that a mermaid had entered Holland through a dike, and was injured in the process. She was taken to a nearby lake and soon nursed back to health. She eventually became a productive citizen, learning to speak Dutch, perform household chores, and eventually converted to Catholicism.
Another mermaid encounter once offered as a true story is described in Edward Snow's "Incredible Mysteries and Legends of the Sea." A sea captain off the coast of Newfoundland described his 1614 encounter: "Captain John Smith [of Jamestown fame] saw a mermaid 'swimming about with all possible grace.' He pictured her as having large eyes, a finely shaped nose that was 'somewhat short, and well-formed ears' that were rather too long. Smith goes on to say that 'her long green hair imparted to her an original character that was by no means unattractive.'"
In fact Smith was so taken with this lovely woman that he began "to experience the first effects of love" as he gazed at her before his sudden
(and surely profoundly disappointing) realization that she was a fish from the waist down. Surrealist painter Rene Magritte depicted a sort of reverse mermaid in his 1949 painting "The Collective Invention."
Modern mermaids?
Could there be a scientific basis for the mermaid stories? Some researchers believe that sightings of human-size ocean animals such as manatees and dugongs might have inspired merfolk legends. These animals have a flat, mermaid-like tail and two flippers that resemble stubby arms. They don't look exactly like a typical mermaid or merman, of course, but many sightings were from quite a distance away, and being mostly submerged in water and waves only parts of their bodies were visible. Identifying animals in water is inherently problematic, since eyewitnesses by definition are only seeing a small part of the creature. When you add in the factor of low light at sunset and the distances involved, positively identifying even a known creature can be very difficult. A glimpse of a head, arm, or tail just before it dives under the waves might have spawned some mermaid reports.

Modern mermaid reports are very rare, but they do occur; for example, news reports in 2009 claimed that a mermaid had seen sighted off the coast of Israel in the town of town of Kiryat Yam. It (or she) performed a few tricks for onlookers before just before sunset, then disappearing for the night. One of the first people to see the mermaid, Shlomo Cohen, said, "I was with friends when suddenly we saw a woman laying on the sand in a weird way.
At first I thought she was just another sunbather, but when we approached she jumped into the water and disappeared. We were all in shock because we saw she had a tail." The town's tourism board was delighted with their newfound fame and offered a $1 million reward for the first person to photograph the creature. Unfortunately the reports vanished almost as quickly as they surfaced, and no one ever claimed the reward.
In 2012 an Animal Planet special, "Mermaids: The Body Found," renewed interest in mermaids. It presented the story of scientists finding proof of real mermaids in the oceans. It was fiction but presented in a fake-documentary format that seemed realistic. The show was so convincing that the National Oceanic and Atmospheric Administration received enough inquiries following the TV special that they issued a statement officially denying the existence of mermaids.
A temple in Fukuoka, Japan, is said to house the remains of a mermaid that washed ashore in 1222. Its bones were preserved at the behest of a priest who believed the creature had come from the legendary palace of a dragon god at the bottom of the ocean. For nearly 800 years the bones have been displayed, and water used to soak the bones was said to prevent diseases. Only a few of the bones remain, and since they have not been scientifically tested, their true nature remains unknown.
The existence of merfolk (mermaids and mermen) has been a fascination and a topic of question for people for thousands of years now. This belief consists of the idea that there were aquatic humanoids, residing in the depths of the sea that were some sort of half fish, half human hybrid. Information on merfolk appears in Japanese legend, Greek mythology, ancient folklore, and through tales of medieval sailors who clam to have encountered “sea maidens.”
This belief was most popular during medieval times, but is even popular to this day, as Animal Planet’s “Mermaids: The Body Found” series, which aired in the 2000’s, was the most popular show in Animal Planet history. It is important and extraordinary because even though there is no real evidence for it, the idea of these fish people has still inexplicably attended to the minds of almost all sea-faring people for thousands of years.

Evidence (which lots of people claim to be REAL evidence) for mermaids was presented in Animal Planet’s series. It claimed that mermaids were real, and scientists from the NOAA (National Ocean and Atmospheric Administration) were hiding their secrets of mermaids from the world. Although Animal Planet did include a disclaimer saying “This two hour special is science fiction based on some real events and scientific theory.”
The documentary series also presented a clip of a supposed mermaid washed up on the coast of Israel in 2009. Other evidence of the existence of mermaids is only spoken through word of mouth from sailors and sea-faring people who have claimed to have interacted with merfolk; this was mostly during medieval times when their existence was essentially assumed, just as much as the existence of other sea creatures was assumed. Stories say they were associated with misfortune and death, trying to lure sailors off their course.
Japanese legends have their own embodiment of merfolk called “kappa” which were water spirits that appeared less human than other depicted merfolk, but interacted with people and challenged them to games, in which the consequence for losing was death. Modern evidence against mermaids claim that the human-sized ocean animals that are described in folklore are simply sea animals such as manatees .
A statement from the NOAA simply says that there are highly classified real evidence of aquatic humanoids has been found.
Those who believe in merfolk could possibly be mistaken or interpreting their anecdotal evidence wrong, as a source says that the supposed “half fish-half human” being that sailors claim to have seen at sea could have been a different sea creature, since only a small part of the creature was seen along with the contributions of low light at sunset and the distances from which they were seen.
It is basically saying that being able to identify these creatures at all would be very hard. This is why people who claim to have seen mermaids could possibly be mistaken.
The belief of mermaids mostly comes from the sea-faring people’s community. Social influences that help them to sustain this belief are eye witness sightings and stories passed among them of sightings and interactions with mermaids.
Psychological explanations for the belief system of mermaids is that there is no physical evidence for or against mermaids; no one can yet prove that they did exist, yet people who have spent lots of time at sea claim to have seen and interacted with these aquatic phenomenons. They have somehow been a topic of interest among people for thousands of years now, and will continue to be an extraordinary belief of the sea-faring community until they are proven fact or fiction.
Other encounters were more harmless. In 1430 in the Netherlands, it was said that after the dikes near the town of Edam gave way during a storm, some girls rowing around in a boat found a mermaid “floundering in shallow, muddy waters,” according to the Standard Dictionary of Folklore, Mythology, and Legend. “They got her into the bat, took her home, [and] dressed her in women’s cloths,” which was a solid choice on account of her being a woman. She couldn’t be taught to speak, however, and remained totally mute.
Now, it was a pervasive ancient belief that every land animal must have a counterpart in the sea, and humans were no exception. Clearly, there must be sea cows and sea horses and sea swine out there. So while we had the mermaid representing us in sea, some claimed that things got even more specific, and that the clergy had their own aquatic representatives.
In the mid-16th century the French naturalist Guillaume Rondelet supposedly got his hands on two specimens bearing a striking resemblance to a pair of religious types: monks and bishops. The Encyclopaedia Metropolitana of 1817 describes the supposed “sea monk” accordingly: “The face was human, but coarse and clownish, the head smooth and without hair, a sort of hood resembling that of a monk covered the shoulders,” while its “lower parts ended in a spreading tail.” The “bishop fish” was “yet more wonderful, being clad by nature in the garb of a bishop.” It was taken to the king of Poland, who in his benevolence decreed it be carried back to the ocean and set free.
But out at sea, the number of mermaid sightings exploded as the Age of Discovery kicked off, as men in big, expensive boats made their way around the world. John Smith, of Pocahontas fame, caught sight of one off of Newfoundland in 1614, noting that "her long green hair imparted to her an original character that was by no means unattractive." And in 1493 the expedition of Christopher Columbus took time out of their wanton murdering to sight the mythical mermaid near what is now the Dominican Republic.
As Columbus wrote in his diary: “The day before, when the Admiral was going to the Rio del Oro, he said he saw three mermaids who came quite high out of the water but were not as pretty as they are depicted, for somehow in the face they look like men.” And then they got back to the murdering and enslaving.


In reality, the admiral had likely seen a manatee (what Smith had seen is anyone’s guess, considering manatees don’t venture that far north). And indeed it was strange creatures like these, a group known tellingly as the sirenians that also includes dugongs, that explorers encountered as they made their way around the world.
Sadly, they ended up driving the most incredible sirenian to extinction: Steller's sea cow. At an astonishing 33 feet long and 24,000 pounds, it was 20 times heavier than the manatee. But because it was so large, it never needed to fear predators before humans. By the turn of the 19th century, it was gone.
But it was the dugongs that were likely the source of the myth in the first place. They swim the waters around what used to be the former Syrian and Babylonian empires, and could well have inspired the half-human half-fish gods Atargatis and Ea. And as Michael Largo notes in his Big, Bad Book of Beasts, the mermaid as a bad omen could come from ships sailing too close to shore, where sirenians congregate, only to run aground. Because when in doubt, blame the harmless aquatic mammal.
But as science and reason solidified their hold in European and American society, the mermaid slipped further out of natural history and deeper into sailor lore. After all, out on the high seas, it never hurts to dream. I mean, it worked for Tom Hanks when he got rescued by a mermaid in Splash, and look at him now. He's got, like, Oscars and stuff.
Mermaids may be ancient, but they are still with us in many forms; their images can be found all around us in films, books, Disney movies, at Starbucks — and maybe even in the ocean waves if we look close enough.
