Secondary buds from separate systems can compete. A Zooids, primary buds, and all but two secondary buds were removed from a three-system colony. B By 3 days post-surgery, both secondary buds had migrated to fuse with the vasculature and commensurately increased in size. C On day 6 after surgery, one secondary bud (left side) had reached its maximum size before being developmentally suppressed by the winner secondary bud (right side). D A single secondary bud persisted, and the loser secondary bud had completely resorbed. dps days post-surgery. Scale bars = 1 mm
