The oarfish possesses distinct features that could contribute to the sea serpent descriptions.  Its elongated body, resembling a serpentine shape, along with its undulating movements through the water, might give the impression of a large, snake-like creature. Additionally, the oarfish has long, red or silver-coloured fins running along its back, which could be mistaken for humps or coils. oarfish Due to its preference for deep waters, the oarfish is seldom encountered near coastal areas, making sightings infrequent and increasing the chances of misidentification.
