In European folklore, mermaids (sometimes called sirens) and mermen were natural beings who, like fairies, had magical and prophetic powers. They loved music and often sang. Though very long-lived, they were mortal and had no souls. Many folktales record marriages between mermaids (who might assume human form) and men.
Sexually tantalizing and devastatingly lovely, mermaids are perfect pinups for feminine (yin) power. ... Mermaids are often depicted holding combs (made of fish bones) – this is an ancient nautical symbol of power over nature as sailors believed fish bones could divine or control storms at sea.
