There are plenty of stories from sailors and marines that came across what appears to be monsters of the sea. These range from beautiful sirens to behemoths such as Leviathans, but there is a reoccurring theme here, to say the least.

For example, we have the ancient Greeks that told us that the sirens were half-woman half-bird creatures that used their alluring voices to attract men. We refer to these as mermaids nowadays, not sirens though.

The depiction changed with time as now we believe that mermaids are beautiful half women half-fish creatures that have been depicted all around the globe, from Europe to Asia to Africa.

They usually come about during floods, storms, and shipwrecks and are portrayed as benevolent creatures that can even fall in love with humans.

Even one of the most famous explorers of all time Christopher Columbus himself reported having spotted mermaids while exploring the Caribbean. But he’s not alone on this either, as multiple sightings have also been reported in the 20th and 21st centuries in Canada, Israel and Zimbabwe. What’s even stranger is that there is a congenital disorder known as Sirenomelia which causes the baby to be born with its legs conjoined and small genitalia which has been reported to have affected one out of 100,000 live births so far.

This is why many people now believe that these mermaids were never aliens, to begin with, but humans that suffered from Sirenomelia and decided to live underwater after all. Watch the following videos which show us 6 of these mermaids at the Great Barrier Reef and see for yourself how eerily similar to humans they are.
