A sea serpent, or sea dragon, is a mythological dragon either wholly or partly serpentine. They are described in various mythologies, most notably Mesopotamian, Hebrew, Greek, and Norse.
The Drachenkampf myth theme, the chief god in the role of the hero slaying a sea serpent, is widespread both in the Ancient Near East and in Indo-European mythology. Sightings of sea serpents have been reported for hundreds of years, and continue to be claimed today.
Cryptozoologist Bruce Champagne identified more than 1,200 purported sea serpent sightings. Despite these numerous sightings, no credible physical evidence has been recorded and it is currently believed that the sightings can be best explained as misidentification of known animals such as oarfish and whales. Some cryptozoologists have suggested that the sea serpents are relict plesiosaurs, mosasaurs or other Mesozoic marine reptiles, an idea often associated with lake monsters such as the Loch Ness Monster.
"Origin: North Seas. Giant snakes that dwell at sea. They are of low intelligence, but have great strength. They are said to have smooth heads similar to turtles or horses, and manes. Sprinkling the resin of the Agi plant on yourself will drive away serpents due to the smell."
