10 Animals That Can Literally Bring Themselves Back to Life
10. Mexican Walking Fish (Axolotl’s Cousin) – The Self-Healing Amphibian

While the axolotl gets much of the attention, its lesser-known cousin, the Mexican Walking Fish (a type of salamander) possesses similar but even more surprising regenerative abilities. Unlike most amphibians, this species can regrow nearly any part of its body, including entire limbs, parts of the heart, and even sections of its brain. Scientists have discovered that these creatures can regenerate without scarring, maintaining the full function of the regrown tissue—a feat unheard of in mammals. Even more astonishing? Unlike the axolotl, some Mexican Walking Fish can transform into land-dwelling salamanders if environmental conditions change, effectively "reviving" into an entirely new phase of life. This makes them one of the few animals that can both regenerate AND shape-shift when necessary for survival.
