Abstract: Ultrastructural alternations in the in the gill architecture of the mangrove crab Sesarma brocki were observe on chronic exposure to 10% and 30% of the 96hr LC50-value (10.91 mg/l) of copper. In the gill tissue of control crab gill epithelial cell and pillar cell nucleus were having dispersed chromatin, abundance of mitochondria was visualized. In the gill cells of low toxicity exposed crab condensation of chromatin, swelling of mitochondria and numerous vesicles were seen. High sublethal toxicity inflicted crab gill tissue revealed fragmentation of chromatin and infiltration of nephrocytes also called as podocytes into the haemolymph spaces were observed. The present remarkable ultrastructural alterations on exposure to copper could serve as “Biomarker” for assessing heavy metal toxicity in the aquatic environment.
