Yopyscs
Yopyscs is a hypothetical genus of fictional organisms that inhabit the subterranean cave systems of the planet Xylos. These creatures are characterized by their bioluminescent properties, which they use for communication and navigation in the perpetual darkness of their environment.

Their diet consists primarily of phosphorescent fungi and mineral deposits found within the caves. Yopyscs are
