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.
Removal of the salivary glands of mice [35] and rats slows wound healing, and communal licking of wounds among rodents accelerates wound healing. [36] [37] Communal licking is common in several primate species. In macaques, hair surrounding a wound and any dirt is removed, and the wound is licked, healing without infection. [38]
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.

While most species require the central body to be intact in order to regenerate arms, a few tropical species can grow an entirely new starfish from just a portion of a severed limb. [2] Starfish regeneration across species follows a common three-phase model and can take up to a year or longer to complete. [ 2 ]
The difficulties of using live animals on live television provided most of the humor for the few seconds of the bird's appearance. [ 5 ] In the video game Age of Mythology: The Titans , a myth unit available to the Atlanteans is the Caladria, which serves as a flying scout and healer, though it more closely resembled an angel than a bird.
Plants and animals have the capacity to seal and heal wounds. In all plants and animals examined, firstly a self-sealing phase and secondly a self-healing phase can be identified. In plants, the rapid self-sealing prevents the plants from desiccation and from infection by pathogenic germs.
