Abstract or Summary
  • The cuticle of the cercaria of Acanthatrium oregonense was studied by means of electron microscopy and histochemistry. The integument of this cercaria has a definite ultrastructure which varies in different regions of the body. The body cuticle is a syncytium containing vesicles and mitochondria. It is bounded externally by a double surface membrane and internally by a basement membrane. The vesicles were grouped morphologically into three types, two with fibrillar contents and the third containing homogeneous electron-dense material. The sucker is a modification of the body cuticle and contains vesicles of only one of the three types and no mitochondria. The tail cuticle has the same three layers (surface membrane, cytoplasmic layer, basement membrane) as the body cuticle, but no vesicles are present. Instead there are small elongate cavities along the periphery of the cuticle. Chemically the body cuticle and sucker may be differentiated from the tail cuticle by the presence of acid mucopolysaccharides. The subcuticular layer of the body has a concentration of glycogen. The differences in chemistry and morphology of the body and tail cuticle may be related to the temporary nature of the tail.
