A white-headed dwarf gecko with tail lost due to autotomy. 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.
Alligators can regrow their tails, it turns out. Researchers have discovered that these ancient reptiles that date back to dinosaur days and can grow 14 feet long or more can regenerate themselves ...
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.

The feature of the axolotl that attracts most attention is its healing ability: the axolotl does not heal by scarring and is capable of the regeneration of entire lost appendages in a period of months, and, in certain cases, more vital structures, such as tail, limb, central nervous system, and tissues of the eye and heart. [28]
The axolotl can grow up to 12 inches and weigh anywhere from three to eight pounds, and its average lifespan in the wild is 10-15 years. Most axolotls are dark brown with some black speckling, but ...
An interesting fact about them is that they can regenerate lost limbs, their tail and even parts of their hearts and eyes. Up Next: Related: 29 Unique Animals That Start With the Letter ‘X’
Such species generally can regenerate the lost part of a tail, though imperfectly. A lost tail can grow back within around three to four months. [6] Species with stumpy tails have no special regenerative abilities. Some species of skinks are quite small; Scincella lateralis typically ranges from 7.5 to 14.5 cm (3 to 5 + 3 ⁄ 4 in), more than ...
The central argument for declawing is that because crabs can regenerate lost limbs, it is inherently more sustainable than the capture of whole crabs. [14] Yet claws are a large portion of a crab's biomass, ranging from 20% to over 50% of some species' total weight, and thus regeneration can be highly energy- and time-consuming.
