Sealses

Sealses are a fictional species originating from the planet Xylos. They are known for their bioluminescent skin, which they use for communication and navigation in their planet's dim environment. Physically, sealses are bipedal, with slender limbs and large, dark eyes adapted to low light conditions. They possess a unique respiratory system that allows them to absorb oxygen directly from their atmosphere, which is rich in methane.

The society of sealses is highly communal, with individuals often forming deep, telepathic bonds with one another. This allows for efficient information sharing and a strong sense of collective identity. Their culture emphasizes harmony with their environment and a deep understanding of Xylos's complex ecosystems. Sealses are primarily herbivores, feeding on a variety of phosphorescent fungi and mineral-rich subterranean plants.

Their technology, while not as advanced in areas like space travel, is highly sophisticated in bio-engineering and energy manipulation. They have learned to harness the planet's geothermal energy and have developed organic tools that integrate seamlessly with their biology. Little is known about their history before the recorded era, but ancient glyphs suggest a long and peaceful existence focused on exploration and understanding of their home world. Encounters with other species are rare, as Xylos is located in a remote sector of the galaxy.
