Zhuru(朱獳) is a mythical beast that lives in the mountains. It looks like a fox with fins like a fish. Its cry sounds like it is calling its own name. Wherever it appears in a country, that country will experience something that causes fear.
《山海經 東次二經》
又南三百裏，曰耿山，無草木，多水碧，多大蛇。有獸焉，其狀如狐而魚翼，其名曰朱獳，其鳴自，見則其國有恐。
