Methods

The present review was completed to comprehend the dissemination of benthic and

planktonic foraminifera. The zooplankton net was pulled for 5-min span to

gather planktonic foraminifera under locally available condition. The copy dregs

tests were gathered utilizing Van Veen Grab for the benthic foraminifera. The

subsamples were taken by utilizing a PVC corer (with an interior measurement of 2.5 cm,

furthermore, a length of 5 cm) from the center of every get test. After specimen gathering,

5 % formaldehyde was included into the examples for safeguarding. Along

with the tiny fish and residue tests gathering the natural information too

gathered utilizing the Quanta Hydrolab test. The protected specimens were brought

to the lab and the microscopic fish tests were splitted utilizing the Folsom Splitter.

The silt tests were washed with channel seawater through an arrangement of 500 and

63 lm sifters for partition of foraminifera. The isolated tiny fish and residue

tests were seen under a stereoscopic binocular magnifying lens (Nikon—

SMZ1500) for partition of foraminifera and photographs were taken under the Zeiss

computerized magnifying lens. The recognizable proof was completed in view of the standard precise

keys and the writing (Loeblich and Tappan 1964).

2.3 Results and Discussion

The reviews on the foraminiferal dispersion in the waters and dregs of the

Port Blair and Little Andaman environment proposed that there are 189 species

(Table 2.2). Of the 189 species, 170 species are from the residue tests and 19

species recognized as planktonic specimens (Figures 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8,

2.9, 2.10, 2.11, 2.12, 2.13, 2.14). Among 170 types of residue tests, 115

species are from the Little Andaman and 76 species from the Port Blair. Twentyone

species are regular in both the situations.

On account of planktonic specimens, the recognized 19 species under eight genere

are gathered into two classes viz., Little Andaman and Port Blair situations.

Twelve species fallen in Little Andaman environment and Port Blair environment

display eight species. Out of 19 species, two species are normal in both the
