Sunflower sea star regenerates its arms. Dwarf yellow-headed gecko with regenerating tail. Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.

He says that the animal world offers remarkable repair and regeneration examples, but that some of that genetic information would have been “unnecessary for early mammals that were lucky to not ...

Epimorphosis is defined as the regeneration of a specific part of an organism in a way that involves extensive cell proliferation of somatic stem cells, [1] dedifferentiation, and reformation, [2] as well as blastema formation. [3]
All cnidarians can regenerate, allowing them to recover from injury and to reproduce asexually. Hydras are simple, freshwater animals possessing radial symmetry and contain post-mitotic cells (cells that will never divide again) only in the extremities. [14] All hydra cells continually divide. [15]
Unidirectional regeneration is the simplest form of regeneration as the majority of the disk is intact, allowing the starfish to eat, move, and escape predators during the regeneration period. Unidirectional regeneration is also the most common form of regeneration exhibited by starfish as single arms are often removed by predators or shed ...
Unlike the limited regeneration seen in adult humans, many animal groups possess an ability to completely regenerate damaged tissue. [4] Full limb regeneration is seen both in invertebrates (e.g. starfish and flatworms which can regenerate fully functioning appendages) and some vertebrates, however in the latter this is almost always confined to the immature members of the species: an example ...
Autotomy (from the Greek auto-, "self-" and tome, "severing", αὐτοτομία) or 'self-amputation', is the behaviour whereby an animal sheds or discards an appendage, [1] usually as a self-defense mechanism to elude a predator's grasp or to distract the predator and thereby allow escape. Some animals are able to regenerate the
