What is a brief description of where Medusa is from and where Medusa can usually be found?

They are conceived by Hesiod to live in the Western Ocean, in the neighborhood of Night and the Hesperides. But later traditions place them in Libya. They are described as girded with serpents, raising their heads, vibrating their tongues, and gnashing their teeth; Aeschylus adds that they had wings and brazen claws, and enormous teeth.
