The group is also unique among the invertebrates in the variety of test shapes and styles of chamber arrangement developed, in some cases achieving an architectural complexity that has anticipated the geodesic domes of Buckmaster Fuller. DISCUSSION Evidence for asexual reproduction in culture Planktic foraminifera are normally observed to reproduce sexually in culture (6, 7, 13). Test Morphology: Foraminifera are animals which build a shell; and for paleontologists the characterstics of the shell are the primary features which can be used to distinguish one species from another. Carbon dioxide excursions and the deep sea record: aspects of the problem. foraminifera were recognized by Dujardin as protozoa, and shortly afterwards, d’Orbigny produced the first classification of foraminifera, which was based on test morphology.

This evolutionary plasticity among early Foraminifera makes their present morphology-based classification of limited value. The last magnum opus on foraminifera dates back to 1988, when Loeblich and Tappan published a comprehensive work about the taxonomy of foraminifera with a description of 878 genera. Together, this indicates that morphological heritability may be low across Foraminifera or at least in taxa exposed to a high degree of environmental instability such as planktic and shallow-living benthic foraminifera. They are microscopic in size, and generally range from 0.1 to 1 mm. Nourishment was provided by symbiotic photosynthesizing algae.

The cross commonality of units within the clones of all individuals therefore defines the genetic type. Environmental conditions such as temperature and trace elements may play an important role in stimulating such unusual test occurrences. In this volume John Murray investigates the ecological processes that control the distribution, abundance, and species diversity of benthic foraminifera in environments ranging from marsh to the deepest ocean.
