[Summary:]
The distribution of six species of polychaetes viz., M. gravelyi, D. variabilis, G. embranchiata, O. eremita, C. insecta and L. medusa has been studied on the basis of percentage of occurrence at various stations in the Adyar estuary, Madras. Among the polychaetes studied M. gravelyi was found to exhibit the greatest penetration occurring in regions where salinities were as low as even 5-10 parts per mille. It is argued that besides factors like salinity, temperature, availability of food, protection to eggs, abbreviations of stages in the life history and precocious development of nephridia in the larvae, factors like capacities for tolerance of salinity and abilities for osmotic regulation as reflected in the grades of structural modifications of nephridia, may have played an equally important role in the successful establishment and distribution of these polychaetes in the estuary.
