Oceanids are sea nymphs in Greek mythology, often depicted as beautiful maidens who personify the ocean's various aspects. They are the daughters of the Titan Oceanus and the Titaness Tethys. Each Oceanid represents a specific body of water, such as rivers, springs, and seas, and they are associated with the nurturing and life-giving qualities of the ocean. In total, there are said to be around 3,000 Oceanids, highlighting their vast presence in the mythological world. They often appear in stories alongside other deities, such as Poseidon, the god of the sea, and are known for their roles in various myths, including those involving heroes and sailors.
