How does the regenerated whiptail tail often differ structurally from the original tail?

Answer

Frequently appearing somewhat blunter or differently colored

While the ability to shed the tail via autotomy ensures survival during an attack, the tail does eventually regenerate. However, this regenerated appendage is often not an exact replica of the original structure lost during the defensive maneuver. Specifically, the regenerated tail frequently appears somewhat blunter in shape or exhibits a different coloration compared to the initial tail that was sacrificed.
