Abstract: An attempt has been made to know the distribution of planktonic foraminifera in the continental shelf slope region between Chennai and Cuddalore in the Bay of Bengal collected during a cruise. Fifteen species were identified from forty five grab samples. The total population is found to increase significantly from 30 m to the deeper region with maximum average of 41 % observed in the samples from beyond 200 m of water depth. However, samples from less than 10 m witnessed only 1.4 % of planktonic foraminifera. Results reveal that the spinose forms outnumbered the non spinose forms making up 80 % of the total population.
