Lucky or unlucky, it is interesting that the mythology of mermaids seems to stretch worldwide. European countries tended to have a more negative view of the creatures but many countries in the Pacific Isles see them as signs of good fortune or better. In Warsaw, Poland the mermaid is the symbol of the city and tales of mermaids have come everywhere from central Africa to Canada to Israel. That's a whole lot of places for a creature that isn't supposed to exist.
