Abstract:

The cuticle of Centrorhynchus milvus acanthella and cystacanth larvae, obtained from the terrestrial crustacean Porcellionides pruinosus, is roughly 0.2 micron thick. The cuticle of juveniles encysted in toads, paratenic hosts, measures up to 0.5 micron whereas that of adults may exceed 2 microns in thickness. In all cases it is perforated by numerous pores that communicate with the hypoderm. During larval development, the numerous endocytotic vacuoles observed in acanthella 3, 4, and 5 and cystacanths became elongated canals in juveniles and adults. There is no significant ultrastructural modification in the cuticle. In the larvae, on the other hand, there was progressive thickening of the cyst wall.
