Amoeboid movement of spheroid or ovoid immature or mature macrogamonts within cultured Madin-Darby bovine cells usually began with the formation of a pseudopodium-like protrusion at the margin of the gamont. The protrusion enlarged as the gamont cytoplasm and nucleus moved into the protruded area. During movement, macrogamonts had an elongate shape. The body of the gamont was constricted as it moved through the cell cytoplasm or from one cell to an adjacent one. After movement had ceased, the gamont resumed its ovoid or spheroidal shape.
