Abstract

An electron microscopic study of the teguments of the late acanthella and the cystacanth acanthocephalan Acanthocephalus tenuirostris obtained in the experiment was carried out. The late acanthella is characterized by a bilayer cyst and signs of intense secretion in the surface part of the tegument. A cystacanth is characterized by a cyst and a thick layer of glycocalyx on the surface of the tegument, which are closely adjacent to each other along their entire length. During the preparation of some cystacanths, the cyst received mechanical damage; in these cystacanths, shedding of a thick layer of glycocalyx and associated cyst was observed.
