Abstract: | This examination represents the first scanning electron microscopic study of a proteocephalid tapeworm, Proteocephalus ambloplitis, and it also serves as the first comparative study between the adult and larval stages of a tapeworm. Proteocephalus ambloplitis has numerous microtrichs whose densities and diameters differ greatly from those of cyclophyllidean and pseudophyllidean tapeworms previously examined. Proteocephalus ambloplitis also has an external apical organ and a subcuticular organ. |
