Alligators can regrow their tails, it turns out. Researchers have discovered that these ancient reptiles that date back to dinosaur days and can grow 14 feet long or more can regenerate themselves ...
Some amphibians and certain species of fish and two species of African spiny mice can produce blastemas as adults. [5] For example, salamanders can regenerate many organs after their amputation, including their limbs, tail, retina and intestine. [6] Most animals, however, cannot produce blastemas.
The axolotl can grow up to 12 inches and weigh anywhere from three to eight pounds, and its average lifespan in the wild is 10-15 years. Most axolotls are dark brown with some black speckling, but ...
The feature of the axolotl that attracts most attention is its healing ability: the axolotl does not heal by scarring and is capable of the regeneration of entire lost appendages in a period of months, and, in certain cases, more vital structures, such as tail, limb, central nervous system, and tissues of the eye and heart.

Some species of skinks are quite small; Scincella lateralis typically ranges from 7.5 to 14.5 cm (3 to 5 + 3 ⁄ 4 in), more than ...
