About Salamanders



Among many invertebrates the ability to regenerate body structures is widespread. Most vertebrates, however, have evolved healing responses to injuries that overrides any possibility for regeneration. Urodeles, commonly called salamanders, are the only vertebrates that are able to completely regenerate limbs as adults. Their limbs are similar in form and function to other vertebrate limbs that cannot regenerate. Scientists have debated how urodeles have retained this remarkable trait and the question still is not fully answered (3). This site concerns how the process of regeneration occurs and the mechanisms envolved in the formation of the new limb.
