Trematodes identified in dolphins (15 Stenella coeruleoalba and 10 Tursiops truncatus), stranded along the Tuscan coastline (central Italy) of the “Pelagos Sanctuary” in the period between February 2013 and July 2015. (A1–A4) Campula palliata adult specimens found in the bile ducts of a striped dolphin (S. coeruleoalba). (A1) Microscopical view of the anterior end showing the oral sucker (scale bar 300 µm); (A2) microscopical view of the middle part of the body showing the ventral sucker (scale bar 1 mm); (A3) microscopical view of the posterior end of the body (scale bar 1 mm); (A4) microscopical view of the entire body of two adult specimens of 12–13 mm in length and 1.7–2.0 mm in width (scale bar 12 mm). (B) Pholeter gastrophilus adult (2.90 mm long and 2.00 mm wide) found in the submucosa of the third gastric compartment of a bottlenose dolphin (T. truncatus) showing a spindle-shaped body, with a cuticle covered with small pointed spines. The uterus, long and folded, is placed marginally and follows the body for almost its entire length. The testicles are ovoid in shape and are placed side by side in the posterior region of the body, while the lobed ovary is placed slightly in front and laterally the testicles, (scale bar 1 mm).
