Behind the scenesEdit
These creatures appeared unnamed in the pilot episode of Star Trek: The Next Generation and were never properly named in canon. The designation "Star Jellies" comes from the Star Trek: Titan novels where they are also referred to as a type of cosmozoans (a generic term including several distinct species such as the Crystalline Entity, the Space Amoeba and Junior's species). They belong to an entire ecosystem of cosmozoan. They are hunted by an alien species known as the Pa'haquel who butcher their bodies to create vessels for them to travel in space.
