Ø The lower estuarine region is characterized by low range of variability and high abundance of foraminiferal counts, while the upper estuary by low range of variability and low faunal abundance.
Ø The living assemblages have limited number of species with Ammonia beccarii being dominant in all seasons.
Ø Of the various ecological parameters studied salinity, pH and calcium have a close bearing on the distribution and abundance of foraminifera in the estuary.
