"These differences suggest that the regenerated tail is less flexible, as neither the cartilage tube nor the long muscle fibers would be capable of the fine movements of the original tail, with its interlocking vertebrae and short muscle fibers," said Fisher, who also is an associate professor in the School of Life Sciences at ASU. After six weeks, the whole shape of the tail has been regenerated. If your pet lizard has lost its tail, you should soak its nub in warm water during the day and frequently clean it out.
