Pungtungia herzi

Pungtungia herzi is a species of cyprinid fish found in Japan and the Korean Peninsula.

Named in honor of German entomologist Alfred Otto Herz (1856–1905), who collected the type specimen.

It has been observed to deposit its eggs into nests of Siniperca kawamebari, allowing the S. kawamebari male to unwittingly guard them until they hatch, which will occur before the S. kawamebari eggs hatch and the male S. kawamebari leaves.
