Ypsigon within the y-cyprid. A fully formed ypsigon located within the y-cyprid and just starting to escape through a hole near the anterior end. All y-cyprid tissues are included in the new ypsigon stage, leaving behind only the empty cuticle and all appendages of the y-cyprid. Note how the thorax (with natatory appendages) and abdomen of the y-cyprid shows distinct segmentation, while the slug-shaped ypsigon is entirely unsegmented.
