A sea serpent is a legendary creature often described as a large, snake-like animal that inhabits oceans and seas. These mythical beings have been reported in various cultures throughout history, often depicted as having long bodies, fins, and sometimes multiple heads. Sightings of sea serpents have been recorded in folklore and maritime tales, leading to speculation about their existence. Many sea serpent stories may have originated from misidentifications of real marine animals, such as oarfish or giant squids. Despite numerous claims of sightings, no scientific evidence has confirmed the existence of sea serpents. They remain a popular subject in literature and popular culture, symbolizing the mysteries of the ocean.
