When confronted with the possibility of being devoured, the common gecko is capable of making a somewhat brutal compromise [...] the lizard can shed the entirety of its own tail as an offering to potential predators.

Eighteenth century explorer José de Almagro claimed to have discovered a much more curious specimen in the mountains of what is today Chile: a gecko which, when threatened, could shed its entire body at once.
