Ti-keel

The Ti-keel are a sentient species of mollusks of the 47th Florescence.

Biology
Ti-keel are giant jellyfish with transparent skin that are facilitator-absorber omnivores. Ti-keel were a fringe minority of sentients as they were classed—“Non-Technological and L-L based.” They represented a third major social pattern found in the galaxy, a race neither predator nor preyed-upon, but one which lived for linkage between other lifeforms, which gained its satisfaction from being an eternal intermediary. To be mobile they use flyer/floaters to levitate themselves.
