National Sea Serpent Day - It's National Sea Serpent Day. It’s time, once again, to try to separate myth and legend from truth and reality.

National Sea Serpent Day 2025 – August 7, 2025

National Sea Serpent Day on August 7 is observed in commemoration of one of the most common sea serpent sightings. Sea serpents, also known as sea dragons, were prevalent in ancient myths and are commemorated on Sea Serpent Day. They were possibly inspired, in part, by the enormous oarfish, which may grow to be 50 feet long and are rarely seen because they dwell thousands of feet below the ocean’s surface.

History of National Sea Serpent Day

National Sea Serpent Day remembers sightings of sea serpents as well as the many other stories that have been told about them. Serpents are typically portrayed as dangerous monsters, as opposed to their so-called predecessor, the innocuous oarfish.During their voyage to Saint Helena in the South Atlantic in August 1848, men and officers aboard the HMS Daedalus reported witnessing a 60-foot-long creature poking its maned head and torso out of the water.One can only imagine the awe and wonder they must have felt upon sighting such a creature. Other stories have emerged over the years of equally incredible sightings. Each story, unsurprisingly, presents different facts that often dispute other accounts. The stories, however, continue to spread.A sea serpent is a mythological and legendary aquatic beast that resembles a gigantic snake. The belief in enormous sea animals was common across the ancient world. Large water species such as whales, sharks, and sea lions have, in many cases, been mistaken for sea serpents. Cryptozoologists, on the other hand, believe that sea serpents are relict plesiosaurs, mosasaurs, or other Mesozoic marine reptiles.Serpent sightings are the stuff of folklore. We may call them marine sirens. Cetus is the name given to the sea creature in Greek mythology. The Kraken was mentioned by the Vikings. Even we land-locked New World beings have names for the serpents that reside in the watery depths of our major lakes and waterways.
