Infection sites of Accacoelium contortum in the ocean sunfish Mola mola (L.) from the Western Mediterranean. a Gill infected with A. contortum with parasites attached (arrow); scale bar = 1 cm. b Detail of (a) showing the infection area with parasites detached, scale bar = 2 mm. c. Detail of (b) showing little swellings (arrows) on gill tissue caused by A. contortum sucker vacuum; scale bar = 2 mm. d Detail of (b) showing little swellings (arrows) in the parasite surface caused by A. contortum suckers; scale bar = 2 mm. e Gill infected with numerous A. contortum clustered inside a pit (arrow) within swollen tissue (inset: a schematic representation where gill tissues covering the parasites are portrayed as semi-transparent in order to show the cluster of parasites below); scale bars = 1 cm (inset 2 mm). f Specimens of A. contortum on the pharynx; note that the cluster of parasites is disaggregated and several parasites lie over the pharyngeal teeth and gill arch (arrow). The gills were also infected by the copepod Cecrops latreillii (arrowheads); scale bar = 2 cm
