Creatures such as the salamander and a Mexican tetra can regenerate. Echinoderm - Echinoderm - Asexual reproduction: Asexual reproduction in echinoderms usually involves the division of the body into two or more parts (fragmentation) and the regeneration of missing body parts. By sequencing an axolotl's genome, scientists hope to discover how the species uses stem cells to regenerate tissue. In biology, regeneration is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. There has been success, however, in fingertip regeneration, particularly in children. … If cut into pieces, each piece can grow into a new worm. Fragmentation is a common method of reproduction used by some species of asteroids, ophiuroids, and holothurians, and in some of these species sexual reproduction is not known to occur. Form II males Australian researchers have isolated an immune system cell in salamanders which helps it regenerate missing limbs and damaged organs — and they suspect the same thing could work in humans, too. Animals. … It can grow back even faster if the crayfish is younger, warmer, and well fed. Animals including seastars, salamanders, planarians (flatworms), crabs and some fish are all capable, to varying degrees, of body part regeneration, ranging from limbs to tails, and on to even eyes and internal organs.

The axolotl, a rare and unusual salamander native to Mexico, has the ability to regenerate an amazing variety of body parts, including entire limbs and even brain tissue. The skink can grow a new tail in three to four months, but it is more vulnerable during that period. Earthworms, starfish, lobsters, snails, salamanders and scores of other creatures can produce their own replacement organs and/or limbs as well. If a predator tries to attack from behind, the tail detaches and keeps wiggling to distract the predator while the skink scurries away. Sharks continually replace lost teeth. The way the regeneration happens is different for each animal, but the consensus is that stem cells play a major part in the process. It can regrow its tail back to full size. amputation, bone morphogenic protein (BMP), fibroblast growth factor (FGF), hydra, injury, planaria, salamander, tissue damage, Wnt/beta-catenin signaling pathway, zebrafish. some species, they can regrow entire bodies out of limbs.
