Received on March 10, 1996; accepted on June 5, 1996 The abundance and species composition of diatoms adhering to the loricae of four agglutinated Tintinnina species, Laackmanniella naviculaefera, Codonellopsis gaussi, Cd.balechi and Tintinnopsis lobiancoi, were determined. Diatoms from the Fragdariopsis group, F.cylindrus and F.pseudonana, dominated on tintinnid loricae from the Antarctic waters, whilst Thalassiosira spp. were predominant on loricae from the Baltic Sea. Although tintinnids utilized diatoms in the environment, it is not a rule that they use only these which are dominant. Our results suggest that certain diatoms are actively selected and agglutinated by particular tintinnid species.
