Gekli

The Gekli, also known as Great Ones, were large living cosmozoans that were native to Fluidic Space. These living creatures were capable of travelling through space under their own power and were able to move at FTL speeds once they built up enough energy for this task. Their existence in Fluidic Space meant that they were often hunted by the Undine who herded them and attempted to control these large beings.

A Great One's internal features allowed for the presence of other races which included another Fluidic Space species known as the Hylasa. This symbiosis was a beneficial one as the Gekli provided transportation along with access to food whilst the Hylasa provided company as well as protection to the young of the Great One. Being deprived of these symbionts led to a Gekli suffering from loneliness that eventually led to their death.

Their senses were acute enough to allow them to find food for both themselves and their passengers. Furthermore, they were able to track and locate a quantum singularitys to allow access to other dimensions such as the one populated by the Milky Way Galaxy. In 2409, contact was made by Starfleet/Klingon Defense Force with the Gekli along with the Hylasa during attempted peace negotiations with the Undine. The Gekli were responsible for allowing the first contact crew to return back to their own dimension.
