Strobilation, however, precludes gonadogenesis and larval brooding by the zooid because gonads develop only in its post-abdomen and larvae are brooded only in its atrial chamber - structures that become disorganized during strobilation (Holyoak, 1992).
I also dissected the post-abdomen from four non-strobilating zooids per wedge and measured the largest oocyte from each one.
