Figure 5. Scissiparity; the formation of a singular stolon during schizogamous epitoky at the posterior end of the T. zebra. Stolon is only partial formed in this specimen; yet to form eyes and sensory receptors. A – Differentiation of the stolon from the body by budding. B – Distinct colour pigmentation change. C – Site for eventual stolon eye development. D – Significantly reduced dorsal cirri.
