Summary
Scolices of_Eubothrium crassum_ from brown trout,E. salvelini from char,E. parvum from mallotus,Bothriocephalus sp. from three-spined stickleback, and_Triaenophorus_ spp. from pike were studied using scanning electron microscopy (S.E.M.) and light microscopy, only the two first mentioned species were sectioned for transmission electron microscopy (T.E.M.). All scoleces examined with S.E.M. were characterized by ‘spherical bodies’ appearing on the scolex surface. Studied with T.E.M. these ‘bodies’ turned out to be cytoplasmic protrusions containing secretory granules. These protrusions seemed to be nipped off as globular structures which freed single secretory granules.
The present study also emphasizes the use of S.E.M. as a tool in cestode taxonomy and clarifies some of the problems and confusion that have surrounded the scolex morphology and shape of_E. crassum_ and_E. salvelini_.
