Pupilians

Pupilians is a term that can refer to multiple distinct concepts, most commonly relating to the pupil of the eye or a fictional species. In the context of the eye, "pupil" is the dark, circular opening in the center of the iris that allows light to enter the retina. The size of the pupil is controlled by the iris muscles, adjusting to regulate the amount of light reaching the eye, thereby affecting vision in different lighting conditions.

Alternatively, "Pupilians" can be used to describe inhabitants or beings associated with a fictional planet or species called Pupilia. These fictional entities, often found in science fiction or fantasy narratives, possess unique characteristics and origins as conceived by their creators. Details about their society, biology, and culture would be specific to the particular work of fiction in which they appear. Without further context, the precise meaning of "Pupilians" remains ambiguous, necessitating clarification to understand the intended subject.
