Of these, simultaneous hermaphroditism has rarely been described. Here, we report a novel case of this phenomenon in adults of the Squalius alburnoides allopolyploid cyprinid complex. We found evidence for the simultaneous presence of mature male and female gonads on the basis of gonad gross morphology and histological analyses. Different stages of male and female germ cell maturation were identified, including motile spermatocytes. We hypothesize on the genetic and/or environmental causes of this phenomenon. ER -
