Shell Morphology, Biometry and Distribution of Some Marine Interstitial Testate Amoebae (Sarcodina: Rhizopoda)

The morphology and biometry of eight marine interstitial testate amoebae (Centropyxiella lucida, Cyphoderia littoralis, Messemvriella filosa, Ogdeniella elegans, O. maxima, Pomoriella valkanovi, Pseudocorythion acutum and Rhumbleriella filosa) were studied by light microscopy and by scanning electron microscopy. Their size frequency distributions were analysed and all studied species was defined as a size-monomorphic. All of them are characterized by a well-expressed main-size class and by a small size range of the shell breadth. Regarding to the shell length P. acutum and O. elegans are characterized by a not well-expressed main-size class in favour of subsidiary classes, but all species have a shell length ranges in close limits. The data about the shell ultrastructure of the species M. filosa, O. elegans, O. maxima and R. filosa are reported for the first time in the literature.
