The morphology of foraminifera tests varies enormously, but in terms of classification two features are important. Foraminifera are one of the most abundant groups in the lagoon of New Caledonia, as shown in the Compendium of marine species from New Caledonia (PAYRI & DE FORGES, eds, 1987): foraminifera (6%), algae (5%), molluscs (23%), arthropods (22%) and vertebrates dominated by fish (19%).

They are microscopic in size, and generally range from 0.1 to 1 mm.

Fossil Foraminifera appear in the Early Cambrian, at about the same time as the first skeletonized metazoans. 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.

Foraminifera (‘hole bearers’), foraminifers or forams for short, are a large phylum of amoeboid protozoans (single celled) with reticulating pseudopods, fine strands of cytoplasm that branch and merge to form a dynamic net. The oldest fossil foraminifera, from the Cambrian, are simple agglutinated tubes.Calcareous microgranular and porcellaneous tests evolved in the Carboniferous, and calcareous hyaline tests in the Permian.Over time, each of these groups has evolved many different forms, including large complex tests associated with reefs. �8�V9��s�{_N*��*�Q�*��E�j�o�:��7>/1rAϳN�A=NN��m��.��_�t�=t��y ��9�6��-�ìX5��Ѵ��߂��r�/��~Z�s�hV��o�%�GR��r�t�O�N�? foraminifera enlarge in a discrete process of serial chamber additions (Fig. 5). h�b```"Oya��1�gfA�E�.��8��7��)g}*�q]�!�9��ZBvݸ��c��kN��h��{��^;��j��6��+K7��'�:96kCGGCZGGCh��b��، &�d01X.

Foraminifera are commonly deﬁned as marine testate protists, and their diversity is mainly assessed on the basis of the morphology of their agglutinated or mineralized tests. For example, the Ant-arctic notodendrodids comprise several morphotypes, including spherical, tubular, and arborescent forms, some of them present together in a single species (27).
