The first sightings of the Gloucester Sea Serpent date from 1638. In 1817 hundreds more sightings were reported of the 40-foot, or 70-foot or even 100-foot creature. The New England Linnean Society of Boston commissioned a local Justice of the Peace to record the testimony of the witnesses and collect evidence. Newspapers had a field day with reports of the chocolate colored creature circling boats and sunning itself on the beach of Ten Pound Island. Sightings were again reported in 1884 and most recently, in 1975.
