The Great New England Sea Serpents

When a New England sea serpent was beached off the coast of Scituate, Mass., in 1970, it marked the continuation of a New England tradition going back to 1638.  Ever since then, sea serpents have frequently visited the New England seashore.

It started in 1641, when credulous English traveler John Josselyn wrote An Account of Two Voyages to New England.  In it, he described a sea serpent seen three years earlier by passersby off the coast of Gloucester, Mass.:

They told me of a sea serpent or snake, that lay coiled up like a cable upon a rock at Cape Ann; a boat passing by with two English on board, and two Indians, they would have shot the serpent, but the Indians dissuaded them, saying that if he were not killed outright, they would be in danger of their lives.

The Gloucester Sea Serpent of 1817

The Sea Serpent

Just a few years after Josselyn recorded the sea monster sighting in Gloucester, someone spotted another creature  off the coast of Lynn, Mass. The sightings would continue for decades.

Some were hoaxes, some may have been giant anacondas and some may have been the product of an overwrought Puritan imagination. The Puritans  seemed all too eager to believe in strange creatures and unearthly phenomena prowling through the wilderness that howled around them.

Snake With Tumors

Not until the 19th century did sea monster sightings happen seasonally. Throughout the summer of 1817, hundreds of people — including the crews of four whaling vessels — sighted a sea serpent in Gloucester Harbor.

The Linnaean Society of New England traveled to Gloucester to collect evidence, distributing questionnaires to witnesses. They found a small serpent with bumpy skin, which they identified as the sea serpent’s baby. After dissecting the serpent, the Linnaeans published a pamphlet announcing the discovery of an entirely new genus, the Scoliophis Atlanticus.

It  turned out to be a ‘ Colubar constrictor with tumors — a cancerous black snake.

Two years later, people reported a serpent off the coast of Nahant, Mass..

Ipswich Sea Serpent

Ipswich Sea Serpent

On Aug. 2, 1868,people saw  a sea monster floundering in a salt marsh on the west side of Eastport, Maine. It looked like a shark, but it seemed part beast and part fish. Spectators rushed to the edge of the marsh to stare at the creature, then shoot at it. It received 70 musket balls, but didn’t die until the next day.

The creature was then taken to Bangor, Maine, and put on display, according to the Bangor Daily News.  It was over 30 feet long and weighed 11 tons with one enormous dorsal fin, two side belly fins, a sharklike tail and two huge legs ending in web feet. Its teeth resembled ‘sharp-pointed popcorn.’ After a while the carcass began to stink, and someone hauled it away before anyone could identify it.


In 1910, off the coast of Ipswich, Mass., a photographer named George Dexter perpetrated a sea serpent hoax. Gordon Harris describes the hoax in the Stories from Ipswich blog:

The caption reads “Only photo of the Sea Serpent posed expressly for Residents at Little Neck Ipswich Mass.” A small child is in the creature’s mouth. Dexter was known for his hoax photos, which included a child sitting in a tree with a wise old owl, and a clam shell as large as the cart that is carrying it.

In November 1970, word went round that a sea monster had washed up on Mannhill Beach in Scituate, Mass. Thousands came to the shore to see the carcass of the 30-foot, four-ton sea monster.

Cecil, the Seasick Sea Serpent

The Harvard Crimson put to rest the belief that ‘Cecil the Seasick Sea Serpent’ was an unknown genus. The newspaper reported Harvard’s assistant curator of Fishes took a long hard look at the ‘monster.’

They have definitely determined that the carcass is that of a mangled basking shark, which may have died at sea and was partially eaten by other sea life as it drifted ashore.

And then came Jaws.

      I have heard of this in my past and a serpent in the north Atlantic may be in my pictorial future. I am an artist. Bless you for the facts and legends.
