Waterman

Waterman: noun. A waterman is a mythological creature in Slavic fairy tales whose name has never been appropriately translated into English. His physical appearance varies from region to region, being represented like a man with a frog´s head in Eastern Slavic folklore and like a green man with webbed hands and feet in Western Slavic folklore. The Eastern portrayal of a waterman is very similar to the Japanese mythical creature known by the name kappa, while the Western one is far more humanoid with personality traits that resemble ones found in humans. Modern examples of watermen include the current presidents of the Czech and Slovak Republic, as well as the people working for the Underwater Law Enforcement Bureau of the Russian Federation.
