American alligators are about as close to dinosaurs as you can get in modern times, and can grow up to 14 feet in length. While much smaller reptiles such as lizards are able to regenerate their tails, the question of whether the much larger alligator is able to regrow their massive tails has not been well studied. A team of researchers from Arizona State University and the Louisiana Department of Wildlife and Fisheries have uncovered that young alligators have the ability to regrow their tails up to three-quarters of a foot, or 18% of their total body length.
