Blood cells are key component of organism for their survival and has profound role in defence mechanism of invertebrates similarly in bivalve species, the key role is healing wound and nutrients transportation. The Anadara antiquata is unique because of haemoglobin in their haemolymph and it is commonly found in Pakistani coast.

 Present investigation revealed three types of Blood cells, namely Red blood cells, White blood cells and platelets, whereas cytochemical analyses denoted that all cells are Periodic Acid Schiff (PAS) and Sudan Black B positive. The nucleus structure supported the stated classification. The ultra-structural studies have shown the abundance of RBC. The present study is contribution in the blood cell morphology of Anadara antiquata.
