The intertentacular organ (ITO) consists of a proximal and distal chamber. Scale bar = 50 /itn. Figure 3. A video image of three extended polypides protruding above the surface of a colony. All three lophophores possess an ITO (arrow heads). A spermatozeugma (arrow) is being spawned through one of the distomedial tentacles of the central lophophore. This tentacle is bent in an abfrontal direction so that the spermatozeugma is released into the exhalent flow of the feeding current passing beneath the canopy of tentacles. Scale bar = 360 ^m. Figure 4. Video images of spermatozeugmata being spawned tail ends first through the tips of the two distomedial tentacles, (a) The tightly bound tail portions of spermatozeugmata (arrow heads) are emerging from the tips of both tentacles. Arrow shows motion of tentacles bending in an abfrontal direction, (b) A spermatozeugma. which has been almost completely discharged, is bent downward at the flexible region (arrow) in the midpiece. The arrow head indicates the portion of the spermatozeugma that is still within the lumen of the tentacle pushing the spermatozeugma out. Scale bars = 150 ^ Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
