Detailed explanation-1: -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.
Detailed explanation-2: -Axolotls. Axolotls are an aquatic species of salamander with extraordinary regenerative ability and are able to regenerate organs, skin, limbs, or practically any other body part.
Detailed explanation-3: -While there are no known mammals that can fully regenerate missing appendages, many harbor hints of regenerative potential-humans included. It has been observed that mice can regenerate the tips of their toes, though loss further up the foot results in the same scarring that humans see after amputation.
Detailed explanation-4: -Abstract. Among vertebrates, urodele amphibians (e.g., axolotls) have the unique ability to perfectly regenerate complex body parts after amputation.
