The animal known for its remarkable ability to regenerate limbs is the axolotl, a type of salamander. Axolotls can regrow not just limbs but also parts of their heart, brain, and spinal cord after an injury, making them a subject of significant scientific interest. This regenerative capability is attributed to their unique cellular structure and genetic factors, which allow them to heal without forming scar tissue. The axolotl’s ability to regenerate has implications for medical research, particularly in understanding tissue regeneration and potential applications in human medicine.
