Morphology of Myxobolus representatives parasitic on the fins and various internal organs of eels, Anguilla anguilla (L.) originating from the Szczecin Lagoon and the Odra River estuary area (Poland) was studied. The sporozoans were found to represent a single species identified as M. portucalensis Saraiva & Molnar, 1990. The infection parameters were determined for the respective organs. The species studied have not been previously reported from the internal organs of the eel and the present record is the first from Poland.
