Further observations on Cercaria parvicaudata Stunkard and Shaw, 1931


, : Further observations on Cercaria parvicaudata Stunkard and Shaw, 1931. Biological Bulletin 99(1): 136-142

Stunkard gives a detailed account of the morphology of Cercaria parvicaudata and of its sporocysts, from Littorina littorea and L. saxatilis. The flame-cell formula of the mature cercaria is 2(3+3+3) + (3+3+3). He is of the opinion that physiological conditions induce the formation of new flame cells from undifferentiated mesenchyme cells. The cercariae will penetrate and encyst in excised parapodia of Neanthes virens, in L. saxatilis, L, littorea and L. obtusata.
