Several animals have the ability to regrow lost limbs through a process called regeneration. Some notable examples include:
1. **Axolotl:** As mentioned earlier, the axolotl, a type of salamander, can fully regenerate not only its limbs but also its spinal cord, heart, and other organs throughout its life.
2. **Starfish:** Starfish have remarkable regenerative abilities and can regenerate lost arms. In some species, a single arm can regenerate an entirely new starfish.
3. **Planarians:** These flatworms are known for their extraordinary ability to regenerate. They can regenerate complete organisms from just a fragment of their body, including lost body parts such as heads, tails, and internal organs.
4. **Certain species of lizards:** Some lizards, such as the green anole, have the capacity to regrow lost tails. This process, known as autotomy, allows them to detach their tails to escape from predators and then regenerate them over time.
5. **Some species of crustaceans:** Crustaceans like crabs and lobsters can regenerate lost limbs through autotomy, as mentioned earlier.
These animals have evolved remarkable mechanisms for regeneration, which have captured the interest of scientists studying tissue regeneration and regenerative medicine.
