Sea monster accounts are found in the folklore of virtually all cultures that have contact with the sea. Some hypotheses suggest that these monsters were based on creatures such as the colossal squid or were surviving specimens of giant marine reptiles from the Jurassic and Cretaceous Periods. Ship damage from tropical cyclones may also be another possible origin of sea monster legends.
