The Caudata ("urodeles"; salamanders and newts), an order of tailed amphibians, is possibly the most adept vertebrate group at regeneration, given their capability of regenerating limbs, tails, jaws, eyes and a variety of internal structures. [2] The regeneration of organs is a common and widespread adaptive capability among metazoan creatures ...
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
Most polychaetes and oligochaetes also use similar mechanisms to regenerate after suffering damage. Two polychaete genera, Chaetopterus and Dodecaceria, can regenerate from a single segment, and others can regenerate even if their heads are removed. [12] [41] Annelids are the most complex animals that can regenerate after such severe damage. [44]

The remarkable ability of salamanders to regenerate is not just limited to limbs but extends to vital organs such as the heart, jaw, and parts of the spinal cord, showing their uniqueness compared to different types of vertebrates. This ability is most remarkable for occurring without any type of scarring. This has made salamanders ...
Mother Nature took no prisoners when she unleashed her wrath on Los Angeles at the beginning of 2025. Wildfires continue to rage in the area, and the death toll now stands at at least 27. Around ...
Various unicellular and multicellular species, including some vertebrates, achieve this state either throughout their existence or after living long enough. A biologically immortal living being can still die from means other than senescence, such as through injury, poison, disease, predation, lack of available resources, or changes to environment.
The Living Planet Index, which draws on data from 35,000 population trends and 5,495 species shows Latin America and the Caribbean have seen the fastest declines in wildlife, with average wildlife ...
