The present study area extends to 150 km from Mandapam to Tuticorin, Gulf of Mannar, Tamil Nadu. Before the commencement of sample collection, a base map in the scale 1: 50,000 was prepared using the toposheet nos. 58L/13, 58L/1 and 58M/16. The fieldwork was done during the month of March, 2006. A total of 74 sediment samples were collected from beach (6), offshore (46) and estuarine (22) in the study region. The offshore samples were collected at six transects keeping the stations at Mandapam (5 nos.), Valinokkam (5 nos.), Vaippar (5 nos.), Vembar (5 nos.), Kallar (5 nos.), Tuticorin (5 nos.), off Tamiraparani (10 nos.) and Punnaikayal (6 nos.).

 
 

Foraminifera have been successful inhabitants of every aquatic environment from deep oceans to brackish water lagoons, estuaries and even rarely in freshwater streams, lakes, etc. In addition, studies on recent foraminifera’s fauna from the seas and other marine marginal water bodies of India, especially along the southeast coast, have to be still explored in detail. Hence, in order to know its distribution in different habitats in Mandpam, Tuticorin, Gulf of Mannar and the Tamiraparani estuary sediments, the present study was taken up to enhance the existing knowledge on foraminifera of east coast of India.
