First report of infestation by a parasitic copepod (Pennella balaenopterae) in a harbour porpoise (Phocoena phocoena) from the Aegean Sea: a case report

An adult, female harbour porpoise ( Phocoena phocoena relicta) was found stranded on the southern Aegean Sea coast of Turkey. Thirteen holes made by copepods were observed on the lateral sides of the porpoise. The copepods were identified as Pennella balaenopterae, based on the morphological characteristics and meas - urement . Tissue samples were collected from embedded parts of parasites, histopathologically examined and pan - niculitis findings were observed. Although this parasite copepod had been reported on several marine mammals, this is the first report in the harbour porpoise, and in the Aegean Sea.
