Abstract

[Foraminifera are single celled protozoans with a very wide distribution pattern ranging from the paralic (littoral) to abyssal depths and with a geological historyGeological history spanning since the Early Cambrian (see Murray 2006). Three major groups of foraminifera are noted, planktic (Fig. 1(1–5)), smaller benthic (Fig. 1(6–9), and larger benthic; the latter are identified by their larger sizeSize and complex interiors, visible in thin sections (Fig. 1(10–12)). The foraminiferal test (Fig. 1(13)) encloses the cytoplasm (soft tissue) of the foraminiferan cellCell with an outer layer called the ectoplasmEctoplasm and an innerInternal/Inner/Inward layer, the endoplasmEndoplasm; the latter gives rise to sticky pseudopodia that traps food for the organism (Fig. 1(14)). The endoplasmEndoplasm contains the nucleusNuclei, cellCell bodies, and organelles (such as mitochondria, golgi apparatus, and ribosomes) (Fig. 1(13)).Fig. 1Major groups of foraminifera groups. Figure 1–55: Planktic foraminifera; 6–9: Smaller benthic foraminifera; 10–12: Larger benthic foraminifera; 13: The foraminiferan test which encloses the cytoplasm (soft tissue) of the foraminiferan cellCell with an outer layer called ectoplasmEctoplasm and an innerInternal/Inner/Inward layer, endoplasmEndoplasm; the latter gives rise to sticky pseudopodia that trap food for the organism (Fig. 1(14)).
