Axolotl
This adorable amphibian can regrow limbs, a tail, a spinal cord, and even parts of its brain — a true regenerative champion.
Starfish
Cut off a starfish’s arm and it can grow it back — some can even regrow their entire body from just one arm.
Green Iguana
When threatened, it can detach its tail and grow it back over time — a smart survival move.
Planarian Worm
Slice it in half, and both parts become a full worm — it regenerates every part, including the brain.
Sea Cucumber
It ejects its internal organs when attacked and regenerates them later — wild and real.
Zebra Fish
Known for regenerating not just fins, but also heart tissue — a favorite in scientific research.
Deer (Antlers)
Unlike bones, deer antlers shed and fully regrow every year — one of the fastest regeneration processes in mammals.
