Nereid



In ancient Greek mythology, the Nereids ( Ancient Greek : Νηρηΐδες) are sea nymphs, the fifty daughters of Nereus and Doris. They often accompany Poseidon and are always friendly and helpful towards sailors fighting perilous storms. They are particularly associated with the Aegean Sea, where they dwelt with their father in the depths within a silvery cave. The most notable of them are Thetis, wife of Peleus and mother of Achilles; Amphitrite, wife of Poseidon; and Galatea, love of the Cyclops Polyphemus. Their fresh-water sisters are known as Naiads

Nereids In Modern Times
In modern Greek folklore, the term "nereid" (νεράϊδα, neráïda) has come to be used of all nymphs, or fairies, not merely nymphs of the sea.

Difference Between the Naiads
Nereids are sea nymphs, but they are only used to sea water, unlike the Naiads that are fresh water nymphs.
