ABSTRACT

Foraminifera has been successful inhabitants of all the marine environment. In order to know their distribution in different offshore habitats, the present study has been undertaken from off Konkan coast, wherein 3 bottom sediment samples were collected at different depth. Faunal analysis of fossil foraminifera from surface sediments collected during the 340th cruise of ORV Sagar Kanya is used to know the bathymetric distribution of the foraminifera in the off Konkan coast, the western continental margin of India. From the present study, based on widely used Loeblich and Tappan’s classification, 26 benthic and 6 planktonic foraminiferal species are identified and counted belonging to 16 benthic genera and 5 planktonic genera, 15 families of benthic foraminifera, and 2 families of planktonic foraminifera. Benthic foraminifera in which Rotaliida (75%) occupies the dominant place followed by Miliolida (20%) and Lagenida (5%). In light of this work, it is inferred that changes in the distribution of foraminifera are basically constrained by physiochemical parameters and geomorphology.
