Sea serpents and sea dragons have been reported by ships for a long time. Some of the sightings remain mysterious and are possibly candidates for undiscovered species. Others seem more likely to be something more mundane. Faced with a topic like this, it is important not to be too quick to decide that all sightings must be true or that all sightings are explained by other things. Each case should be taken on its own merits.
