Oceanids, from Greek mythology, were the nymphs of the great ocean, the daughters of Oceanus and Tethys. There were well over 4,000 of these oceanids. They were sometimes shy, but at other times they were passionate lovers. Most of the time nymphs were kind to mortals, but they sometimes punished people who mistreated them. In the forest, nymphs were represented with fauns and satyrs. You could sometimes find oceanids playing around the keels of ships. Nymphs lived for a long time, but they were usually not considered immortal.
