The animal known for its remarkable ability to regenerate lost limbs is the axolotl, a type of salamander. Axolotls possess extraordinary regenerative capabilities, allowing them to regrow not only limbs but also other body parts, including heart and neural tissues. This remarkable ability has made them a subject of extensive scientific research, as understanding the mechanisms behind their regeneration could have significant implications for regenerative medicine in humans. Their unique properties highlight the fascinating aspects of evolutionary biology.
