“…Regeneration in Myriothelii consists of two phases. a fact that has been reported for other hydroids as well (Shostak 1974). The initial stage, which is the actual phase of repair, results in a healed wound with the body layers arranged in the former order.…”

Myriothela cocksi. a solitary athecate hydropolyp showing many peculiarities and being well investigated concerning gonophore development and embryology, has up to now hardly been examined in respect to regeneration. The simple experiments performed here demonstrate the capacity of all three body regions to regenerate, in due time, previously amputated parts entirely. Further, they reveal a clearly two‐phased regeneration process. The first phase leads to a repaired wound, the second results in a rebuilding of the missing part. Ecto‐ and endoderm are differently involved in regeneration. A greater importance of the endoderm for the first stages of regeneration has been found. Finally, the experiments prove an existing polarity in the polyp. On the basis of these findings it can be concluded that the polyp meets the major criteria of regeneration. This is an absolutely necessary presupposition for all further experiments.

“…Budding rates are proportional to overall rates of cell division rather than the rate in the budding region [15,43,29]. In Hydra viridis (Chlorohydra viridissima) the rate of cell division among gastro dermal (digestive) cells in freshly detached buds is the same as the rate on buds still on parents [3,44].…”

“…Given the absence of mitotic figures in the hypostome, the "number of mitotic figures on the bud proper at the later stage" (stage III) is below that on the parent [32]. Moreover, cell divisions proceed at the same rate in freshly detached buds, during the initial growth period, and in budding animals [32,34,[47][48][49][50][51]. The distinguishing characteristic of the budding region is the local production of new mesogleal components [52][53][54].…”
