Abstract

Seasonal quantitative distributions of the species of the living benthic foraminifera forming the greater part of the foraminiferal population in the Vellar estuary, South India have been studied. Recorded physico-chemical factors have played an important role in controlling the relative abundances of this microfauna. Estuarine foraminiferal assemblage in general shows a quantitative increase with increasingly marine conditions.
