Sea serpent

A sea serpent or sea dragon is a type of sea monster either wholly or partly serpentine. 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. It is currently believed that the sightings can be best explained as known animals such as oarfish, whales, or sharks (in particular, the frilled shark).
