Fig. 7. Visualization of cyprid cement secretion under differential interference
contrast (DIC) optics. A cyprid larva was immobilized in agarose and observed
in a coverslip chamber using an inverted microscope using DIC optics. The
montage shows a series of images separated by 10 s intervals. Images are
arranged starting at the top and going left to right. Note the appearance of a
vacuole that seems to grow larger with time (arrow). Note the increase in size
of the cement sac between frames 1 and 12. See supplemental material for a
