DISCUSSION Evidence for asexual reproduction in culture Planktic foraminifera are normally observed to reproduce sexually in culture (6, 7, 13). The unusual morphology of these foraminifera, “improbable” and rare, is mysterious clues to the natural survival of such organisms. Planktic foraminifera (often referred to as planktic forams) are classified primarily by the ultrastructure and morphology of their tests (shells). Environmental conditions such as temperature and trace elements may play an important role in stimulating such unusual test occurrences. morphology, and five a looser 4.5- to 5-chamber morphology (Fig. traditional morphology-based taxonomy.
