The Women of the Sea: A History of Ocean-Dwelling Women Who Changed Everything

‍"You just have to feel the pull of the ocean — and answer it."

The mermaid is one of the oldest and most universal mythological figures in human history. She appears in ancient Assyrian legend, in Greek myth, in West African folklore, in Scottish and Irish tales of the selkie, in Japanese stories of the ningyo. She is always liminal — belonging to two worlds, fully at home in neither, and more powerful for it. But behind the mythology, there are real women whose relationship with the ocean has been as deep, as transformative, and as radical as any legend.

The Ama: Japan's Sea Women

For over two thousand years, the Ama divers of Japan and Korea have been free-diving into the ocean without the assistance of oxygen tanks or modern equipment, harvesting pearls, abalone, seaweed, and other sea life from depths of up to 30 meters. At its peak, there were estimated to be over 30,000 Ama practicing their craft. Today, their numbers are dwindling — but the ones who remain are extraordinary.

The Ama dive year-round, including in winter waters that would stop the hearts of most adults. They develop extraordinary breath-holding capacity, cardiovascular efficiency, and cold water tolerance over years of practice. Many dive well into their eighties. Their bodies have adapted in measurable ways — Ama divers have been found to have lower rates of certain cardiovascular diseases and higher pain tolerance than non-diving women of the same age.

What's remarkable about the Ama isn't just their physical capability — it's the culture they've built around it. Diving is passed from mother to daughter. The Ama have their own symbols, ceremonies, and customs. Their relationship with the ocean is reciprocal: they take from it only what they need, and they protect it fiercely.

Hydna of Scione: The Diver Who Changed a Battle

In 480 BCE, during the Persian Wars, a young Greek woman named Hydna of Scione dove into a stormy sea alongside her father and swam for ten miles through rough waters to reach the Persian fleet. There, in the darkness, she and her father cut the mooring cables of the Persian warships, setting them adrift in the storm and helping ensure a Greek naval victory.

Hydna was celebrated by the Greeks as a hero. Statues of her and her father were erected at Delphi. She is one of the earliest documented examples of a woman whose mastery of the ocean changed the course of history.

Sylvia Earle: The Woman Who Has Spent More Time in the Ocean Than Anyone

In 1970, marine biologist Sylvia Earle led the first all-female team of aquanauts on a project called Tektite II, spending two weeks living on the ocean floor in an underwater habitat. She has since logged more than 7,000 hours underwater — more than any other human being — and holds multiple world records for solo deep-sea diving.

But Earle's legacy isn't just her time in the water. It's what she's done above it. For five decades she has been one of the ocean's most passionate and effective advocates, founding the organization Mission Blue and dedicating her life to establishing marine protected areas around the world. She has called the ocean "the blue heart of the planet" and argued that protecting it is not environmentalism — it's self-preservation.

"No ocean, no life," she says simply. "No blue, no green."

The Spirit of the Mermaid

What unites these women — the Ama, Hydna, Earle, and the countless others who have made the sea their domain — is a quality that is at the very heart of the Mermaid Soul brand: the refusal to be only one thing. The mermaid lives in two worlds. She is equally at home in the wildness of the ocean and in the beauty and intention of human life above the waterline.

That's the woman Mermaid Soul was made for. The woman who chases waves and also tends carefully to her skin. Who is free-spirited and also intentional. Who is drawn to the ocean not because it's pretty, but because it makes her feel most fully herself.

You don't have to dive to 30 meters or cut a warship's mooring cable to be a woman of the sea. You just have to feel that pull — and answer it.
