Other than marine animals and island inhabitants, another group considered residents of the Atlantis Ocean are seafarers who travel between islands and the mainland, documenting various marine species. Despite a recent influx of peculiar data in the last 100 years, these reports remain consistent because they are supported by substantial physical evidence, such as the discovery of remains from certain marine animals. Thus, these reports were recorded in documents.

           The Atlantis Ocean is currently divided into North Atlantis and South Atlantis, based on the characteristics of the living beings commonly found in those areas. North Atlantis has its main settlement on Maya Island, while South Atlantis is situated on Yamatai Island. However, information regarding cultures and various life forms beneath the ocean remains sparse; it is believed that humans have explored less than 20% of the Atlantis Ocean.
