Scientists at Louisiana Department of Wildlife and Fisheries and Arizona State University have found out that alligators can regenerate their tails. They’d used imaging techniques to come to this conclusion. According to the study, the regenerated tails had a central cartilage skeleton but no bones. The scientists also couldn’t find skeletal muscles in the regenerated tail. However, they were able to see connective tissues and skin. Whatever be the case, alligators need tails to survive as their heavy tails help them in movement. 

It is to be noted that alligators can regenerate their tails only when they are young. Researchers found that American alligators have the ability to regrow their tails up to 9 inches long. The newly grown tail varies slightly in appearance from the rest of the body. It was also identified that there was scale discoloration in the regrown tail.
