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.
The ability and degree of regeneration in reptiles differs among the various species (see [111]), but the most notable and well-studied occurrence is tail-regeneration in lizards. [112] [113] [114] In addition to lizards, regeneration has been observed in the tails and maxillary bone of crocodiles and adult neurogenesis has also been noted.

Hox genes play a massive role in some amphibians and reptiles in their ability to regenerate lost limbs, especially HoxA and HoxD genes. [1]If the processes involved in forming new tissue can be reverse-engineered into humans, it may be possible to heal injuries of the spinal cord or brain, repair damaged organs and reduce scarring and fibrosis after surgery.
Lumbricus terrestris (Linnaeus, 1758) replacing anterior segments from as far back as 13/14 and 16/17 but tail regeneration was never found. Perionyx excavatus (Perrier, 1872) readily regenerated lost parts of the body, in an anterior direction from as far back as 17/18, and in a posterior direction as far forward as 20/21.
Celtic Reptile and Amphibian is a limited company established in 2020, with the aim of reintroducing extinct species of reptile and amphibian (such as the European pond turtle, [99] moor frog, agile frog, [100] common tree frog and pool frog) [101] [102] to Britain. Success has already been achieved with the captive breeding of the moor frog.
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 half of which is the tail. [ 7 ]
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
