Charip
From Multiverses
Charips are an order of bacteria that exists exclusively in the Caverns of Dawn.
Description
All types of Charips are bioluminescent and emit a faint glow, which provides the only source of light in the ecosystem. Still, the Caverns are very dark.
Most Charips are lithotrophs, although a rare few subsist on organic matter.
The Charips form the basis for the Caverns ecosystem, as most forms of life feed on these bacteria.
