The animal known for its ability to regenerate limbs is the axolotl. This aquatic salamander possesses remarkable regenerative capabilities, allowing it to regrow not only limbs but also parts of its heart, spinal cord, and even significant portions of its brain. The axolotl's regenerative process is unique in that it maintains a constant state of embryonic development, which contributes to its extraordinary healing abilities. Researchers study axolotls to gain insights into regeneration, with the hope of applying findings to medical advancements in regenerative medicine and healing in humans.
