Abstract
Based on the LC50 value of copper sulphate (18 ppm) the edible estuari ne crab, Scylla serrata was exposed to a sublethal concentration of co pper (1.8 ppm) for a period of 30 days. The cellular organisation of t he four types of hepatopancreatic cells was affected to different exte nts. A peculiarity was the presence of some enigmatic spherules seques tered and eliminated in the treated crabs. The paradoxical observation was the difference in susceptibility among adjacent tubules, to the p ollutant (viz., copper ions).
