Chapter 5. Interpretive History of the Gloucester Sea Serpent
- Review of previous hypotheses advanced for explaining the Gloucester Sea Serpent by 19th-century natural historians and 19th– and 20th-century cryptozoologists
- The core of the present book represented by a detailed examination of all the evidence to answer the questions as to whether the observed UMO:
- Was an inanimate illusion or a real object?
- Was multiple animals observed together or a single creature?
- Was a giant serpent or something else?
- Had a body that was a single serpentine object or composed of many parts?
- Was a natural phenomena or an anthropogenic artifact in the form of being an animal entangled in fishing gear or other maritime debris?
- Candidate screening and tentative identification of the entangled marine animal behind the Gloucester Sea Serpent based on detailed examination of the observed characteristics of the ‘head’, the displayed locomotory behavior and swimming speed, and the physical location and phenology of the sightings
- Unresolved questions concerning the Gloucester UMO
