Sunulacans
Sunulacans are a fictional species originating from the planet Sunula. Their physiology is adapted to an environment with high levels of solar radiation and a thin atmosphere. They are characterized by a tough, leathery hide that provides natural protection from ultraviolet rays and a respiratory system capable of efficient oxygen extraction. Sunulacans possess a unique bioluminescent capability, which they utilize for communication and navigation in the often dim subsurface caverns they inhabit.
Socially, Sunulacans are organized into communal groups, with a strong emphasis on cooperation and shared resource
