Abstract :
The experiment was carried out on the fresh water bivalve mollusk, Lamellidens
marginalis during January 2019 to December 2020 to study the behavioural changes. The
behavioural changes were recorded in this bivalve when subjected to mean LC concentrations of 50
cadmium chloride for different exposure periods. Different physiological and morphological
changes were observed in experimental animals including protective response, foot movements and
its secretion, response to external stimuli and mucus secretion.
