Morphological characterization of the hemocytes of the clam, Ruditapes decussatus (Mollusca: Bivalvia).
Hemocytes play an important role in internal defence in molluscs. The morphology of hemolymph cells was studied for the first time in Ruditapes decussatus. Two main types of hemocytes (hyalinocytesExpand

Hemolymph cell types of the mussel Mytilus galloprovincialis
Two types of circulating hemocytes were identified in Mytilus galloprovincialis hemolymph: hyalinocytes and granulocytes. The hyalinocytes are agranular cells and show a central nucleus surrounded byExpand
