Abstract: | The surface topography and layering of the cyst wall of the fairy shrimps Streptocephalus dichotomus, S. torvicornis and Thamnocephalus platyurus are described, based on scanning electron micrographs. Cyst walls are not invariably bilayered, but may be composed of up to four layers. They are species-specific in all taxa so far studied. Cyst wall structure within single cysts may differ according to the topographical location on the cyst. |
