Reverse Development in Cnidaria


"Besides their high regenerative and asexual-reproduction potential, a number of cnidarians can undergo ontogeny reversal, or reverse development: one or more stages in the life cycle can reactivate genetic programs specific to earlier stages, leading to back-transformation and morph rejuvenation. The switch is achieved by a variable combination of cellular processes, such as transdifferentiation, programmed cell death, and proliferation of interstitial cells."

From S. Piraino, D. De Vito, J. Schmich, J. Bouillon, and F. Boero. 2004. Reverse development in Cnidaria. Canadian Journal of Zoology 82:1748–1754. doi: 10.1139/Z04-174.
