In this study microsferic and macrosferic individuals of Amphicoryna scalaris (Batsch) collected from 40 stations located between the Gulf of Saros and Marmaris Bay in the Eastern Aegean Sea. Some differences in the test development were observed. The purpose of this study is to prove that the presence of the microspheric individuals of the Amphicoryna scalaris (Batsch) is also rare in the Eastern Aegean Sea, as is around the Corsica Island, Gulf of Naples and Adriatic Sea
