FIGURES 65–70. Renicola sp. "martini" (Rema). 65, Overview of a colony in a freshly deshelled, infected horn snail in sea water. Arrow indicates the colony, which is localized in the gonadal region with infiltration of the digestive gland. Scale bar = 1 cm. Photo from Hechinger and Miura (2014). 66, Close-up of part of a slightly teased apart colony from a freshly dissected horn snail. Individual sporocysts are discernable. Scale bar = 1 mm. 67, Sporocysts, live, with developing cercariae, under heavy coverslip pressure. Note the paletot surrounding the sporocyst tegument. Scale bar = 200 µm. 68, Cercaria, live, under coverslip pressure. Scale bar = 100 µm. 69, Cercaria, live, with no coverslip pressure, with tegumental spines visible. Scale bar = 100 µm. 70, Close-up of cercaria oral sucker, stylet visible, under heavy coverslip pressure, using phase contrast. Scale bar = 10 µm.
