Psamathe was a Nereid (i.e. a daughter of Nereus) who bore Phocus to Aeacus and later, having married Proteus, bore him
Theoclymenus and Eido. Her name means 'sand' (psamathos) - in modern terms we can call her Sandy Shore - for her associations with the beach and the sea. She had turned herself into a seal while trying to escape from the embraces of Aeacus. Significantly, the name of her son by him was Phocus ('seal')!
