The Living Organism, For example, the food particles as well as food residue occupy the last chambers forming a ‘vegetative segment’; the earlier chambers contain the nuclei and other inclusions and constitute the ‘chromatic segment’. The endoplasm of the single chambered forms is more or less homogenous with uniformly

The Test,many years fossil foraminifera were the main subject of foraminiferal study, and consequently the only part of the foraminifer that was studied was the test. For a long time the study of living forms was also concentrated only on the test, even though protoplasmic material was available for study. B

Benthonic Foraminifera of Brackish, Hypersaline, Ultrasaline, and Fresh Waters,e and brackish water areas is different. As a general rule, it is difficult for a marine fauna to penetrate into fresh waters and .. Even when there are available migration routes, faunal mixing is impaired by salinity barriers. For thousands of years water from the Mediterranean Sea (salinity 37‰)

Benthonic Foraminifera of Marshes, Mangrove Swamps and Lagoons,y. The basic source of the water in these areas is the tide or storms although some water is of terrestrial origin, both surface and subsurface. The most characteristic trait of marshes is the active vegetative growth occurring on them. The salinity is commonly lower than normal marine values, usual

Preparation of Samples,nktonic components (for planktonic samples). This process may involve several steps. In the case of consolidated sediments, the sample must be disaggregated, washed and the foraminiferal components separated from the sediment. For those unconsolidated samples taken directly from the ocean bottom the
