Animals With Ability To Regenerate Body Parts

Axolotl Axolotls are an aquatic species of salamander with the extraordinary regenerative ability and are able to regenerate organs, skin, limbs, or practically any other body part.

Chameleons Chameleons are very interesting animals that are well known for their unique ability to blend in with the surrounding environment by changing their colour. Not only that, Chameleons are also able to regenerate their tails and limbs. They can also heal damaged nerves and skin during the regenerative process.

Mexican tetra Like zebrafish, Mexican tetras can regenerate cardiac tissue. Or rather, surface fish can; fish from cave populations have lost the ability. Their hearts scar after injury, more like that of a human. The new study revealed that a number of genes are unregulated in cavefish.

Starfish Starfish can regrow arms that detach from their central disc, and some species have even been observed to complete the process in reverse: regrowing an entire body from a lost arm.

Sharks Sharks can't regenerate organs or other body parts but they can definitely regenerate their dental structures. They lose at least 30.000 teeth over a lifetime, but each lost tooth can be regrown over a period of days or months. 

Salamander Salamanders have been hailed as champions of regeneration, exhibiting a remarkable ability to regrow tissues, organs and even whole body parts, e.g. their limbs. 

Flatworm Planarians are flatworms that possess an amazing ability to regenerate themselves. If you cut one planarian down the middle, each half would reform its missing parts, and you would have two planarians in a matter of weeks.

Sea squirt Marine animals called sea squirts can regenerate their entire bodies from nothing but a tiny fragment of a blood vessel. Their secret is a special population of stem cells floating in their blood. The finding could help us understand how such regenerative abilities evolved.

Deer Deer antlers are the only mammalian appendages capable of repeated rounds of regeneration; every year they are shed and regrow from a blastema into large branched structures of cartilage and bone that are used for fighting and display.
