Sileen

The Sileen are a species native to the ocean world of Silsilaa and one of the earliest species of the 47th Florescence.

Biology
The Sileen are a species of 20 meter long, red-colored, bathypelagic-dwelling worms who dwell about hydrothermal vents scattered along Silsilaa’s tectonic plate boundaries. Their species fed on the bacteria of the hydrogen sulphur from the geysers via chemosynthesis. They are able to communicate with other sentients, by pulsing dots of light in their rhythmic patterns.

Culture
The Sileen are one of the oldest species that had prior contact with the extinct Kokseen.
