In Greek mythology, the sirens were dangerous and beautiful creatures, portrayed as femmes fatales who lured nearby sailors with their enchanting music and voices to shipwreck on the rocky coast of their island.
Mermaids are mythical and legendary sea-dwelling creatures of European & Asian folklore, resembling a woman, with a human torso, but having a fishtail or tails instead of legs. Mermen are also heard of, but have a secondary role in the lore of the sea. Other similar water spirits include nymphs, dryads, oceanids, hamadryads, naiads, nerieds, oreads, and undines. Mermaids are supposed to be able to lure imaginative, amorous men to destruction by enticing them into the depths .
