In Germany the river spirits are called nixies. Although rarely seen, the females are very beautiful with long blond hair and blue eyes. Nixie maidens usually disappear as soon as a mortal appears, leaving nothing but a ripple in the water. But if the man is very handsome, the nixie may lure him into the water, never to be seen again. Those who stalk nixies, will hear their strange singing, causing them to lose their minds.
In Lithuania, there is a strange, though helpful spirit. The Zaltys is a large black snake with a third eye between the two normal ones. The zaltys is a protector of both animals and men, and if one takes up residence in a farmstead, then good fortune will come to the family. The zaltys is rumored to have many magical abilities which it can use to defeat those who would cause unnecessary harm to animals. They are also believed to be appointed by the gods to keep an eye on the moral conduct of men.
