The Shuyu or Shu-fish can be found in abundance in China’s Peng River. It looks like a chicken with red feathers, and has four heads (or four eyes), six feet, and three tails. It caws like a magpie. Eating it cures melancholy.
The red color, multiplicity of appendages, and the triple (three-lobed?) tail combine to suggest a crayfish or lobster.
