Distribution and Habitat
This species was highlighted in News of the Week, 8 February 2021:
Salamanders differ from all other vertebrates in the ability to regenerate lost parts and in their very large and highly variable genomes. Amazingly, salamanders not only can regenerate tails, digits and limbs but also virtually everything else, including much of the brain and the heart. Salamanders long have been known to have gigantic genomes, but what has been missed or ignored is the impact of genome size on the structure and function of genes. These phenomena are directly interrelated, and Session and Wake (2020) proposes dynamic interactions between growth and differentiation affecting morphogenetic processes, pattern formation and regeneration in unique ways. There probably is no specific genetic regulation of regeneration beyond processes normal for salamanders. Regeneration is an extension of their normal development. Salamanders are, in essence, much younger, especially at the cellular level, than implied by their chronological age; they are "forever young”. (David Wake)
