Alligator Tail Regrowth

Caption

The regrown alligator tail is different from the original tail. Regrown scales are densely arranged and lack dorsal scutes (top right). An unsegmented tube of cartilage (yellow) replaces bone (tan) in the regrown tail. Moreover, the regrown tail lacks skeletal muscle (red) and instead, there is an abundance of fibrous connective tissue (pink).
