“Gecko tail drop, or caudal autotomy, is a natural defense mechanism where a gecko intentionally detaches its tail to escape a predator or stress. The detached tail wiggles to distract the attacker, giving the gecko a chance to flee. While some species can regrow their tails (though they may look different), others like Crested geckos cannot.” This one was the type that regrow their tails. | Nnedi Okorafor
