Figure 4. Light microscopy micrographs of Octopus vulgaris haemocytes processed with enzymatic histochemistry analysis: (A) granulocytes showing a peroxidase activity localized as dark brown deposits; (B) haemoblast-like cells with phenol oxidase activity; (C) hyalinocytes with phenol oxidase activity; (D) granulocytes showing phenol oxidase activity. Scale bar = 5 μm.
