The Gloucester Sea Serpent was a serpentine marine cryptid reported in August 1817 and once again in April 1859, when a creature fitting the description of the serpent attacked the British sailing vessel Banner.


Reports of a giant sea serpent that moved rapidly through the harbor were reported in Gloucester. It was said to have a turtle-like head adorned with a spear or horn and a body as wide as a barrel.

In scientific publications

The reports gained so much momentum, the Linnaean Society of New England assembled a team to collect evidence and David Humphreys traveled to collect eyewitnesses reports.

The Linnaean Society of New England published a report that the sightings were evidence about a new animal, Scoliophis atlantica. The name was not appreciated, and received a lot of parodies.
