Oceanids

The Oceanids (Ὠκεανίδες) are the three thousand daughters of the Titans Oceanus and Tethys. One of these many daughters was the wife of the sea god Poseidon, named Amphitrite. Each was the patroness of a particular spring, lake, pond, pasture, flower or cloud. Oceanus and Tethys also had 3000 sons, the river-gods, the Potamoi. Other Oceanids include Asia and Philyra.

Trivia

 * They are called Oceanids derived from the name of their father, Oceanus.
 * They are the elder sea nymphs since their parents were first born than that of the Olympians.
