Biochemical and Ultrastructural Evidence for the Double Role of Phagocytosis in Molluscs: Defense aHaeckel (1862) was the pioneer in reporting that the hemolymph cells of molluscs are capable of phagocytosis. Since that initial report, a number of individuals have demonstrated the phagocytosis of nonself materials by molluscan cells (see Feng, 1967; Cheng, 1967; for reviews).

There is, however, very little consensus of opinion concerning the mechanism of the host’s defense reaction or the means by which a parasitoid escapes it. As has been pointed

The particle is then taken into the phagocyte where it is usually digested following fusion of the phagosome and lysosomes. In the invertebrates, a similar series of events takes pla
