This, however, is not necessarily due to an inherent quality but is probably owing to the ability to operate unimpeded in all three dimensions, in contrast to corresponding ameboid variants, phagocytosing on a substrate. Whole, living trephocytes were repeatedly observed in vitro to be attacked by single, occasionally several, petaloid phagocytes. The trephocytes are caught by the flaps moving their surfaces close to each other and finally over the prey
. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. 56 EMIL LIEBMAN The petaloid forms show the highest phagocytic activity. This, however, is not necessarily due to an inherent quality but is probably owing to the ability to operate unimpeded in all three dimensions, in contrast to corresponding ameboid variants, phagocytosing on a substrate. Whole, living trephocytes were repeatedly observed in vitro to be attacked by single, occasionally several, petaloid phagocytes. The trephocytes are caught by the flaps moving their surfaces close to each other and finally over the prey, some- what in the manner in which a ball is caught in two hands. The engulfed trephocyte is seen moving vigorously within the phagocyte for a considerable time but ulti- mately undergoes gradual digestion, though its movements occasionally help it to "; This peculiar form of phagocytosis is also common within the organism, and whole-blood and toto preparations show a relatively high percentage of phagocytes containing intact trephocytes or some in various degrees of digestion (Fig. 3)..
