Are Mermaids Real?

Mermaids — creatures with the upper body of a human and the tail of a fish — appear in the folklore of nearly every culture that has a relationship with the sea. From ancient Assyria to the Caribbean, stories of mermaids have persisted for thousands of years. But could these beings actually exist?

The Mythology

The earliest known mermaid legend dates back to around 1000 BC in ancient Assyria, where the goddess Atargatis transformed into a mermaid. Greek mythology features sirens (later merged with the mermaid image), and sailors throughout the Age of Exploration regularly reported mermaid sightings — including Christopher Columbus, who in 1493 recorded seeing three "mermaids" off the coast of Hispaniola, noting they were "not half as beautiful as they are painted."

What Were Sailors Actually Seeing?

Marine biologists and historians have offered several explanations for mermaid sightings:

• Manatees, dugongs, and sea cows: These marine mammals swim near the surface and can appear vaguely humanoid from a distance, especially in poor visibility. Columbus's "mermaids" are widely believed to have been manatees
• Seals and sea lions: When resting on rocks, their silhouettes can resemble a human figure
• Loneliness and delirium: Sailors spent months at sea with poor nutrition and isolation — conditions known to cause hallucinations and wishful thinking
• Storytelling tradition: Exaggerated tales were a core part of maritime culture, and reporting wonders was expected of returning sailors

The NOAA Hoax Confusion

In 2012, the U.S. National Oceanic and Atmospheric Administration (NOAA) published a statement on its website titled "No evidence of aquatic humanoids has ever been found." This was in response to a wave of public inquiries triggered by Animal Planet's mockumentary Mermaids: The Body Found, which many viewers mistook for a real documentary. NOAA's statement remains the definitive government position.

Our Verdict

Mermaids are not real. No scientific evidence — no bones, no DNA, no specimens — has ever been found to support the existence of aquatic humanoids. Mermaid legends are a product of human imagination, misidentified marine animals, and centuries of seafaring storytelling.
