The Glothr are a species of aquatic, jellyfish-like methanogens native to the intergalactic rogue planet Invictus. They are a highly advanced sentient species subordinate to the Sh'daar. They first appear in the sixth Star Carrier novel, Deep Time.
Anatomy & Physiology Edit
Glothr resemble cylindrical jellyfish, with bodies about three meters in height. Their tentacles are rather short and do not add much to their overall height. They have twenty-four eyes arranged in three circles around their bodies, granting them 360-degree vision, and they are capable of using bioluminescence to illuminate their bodies in numerous colors.
Glothr biochemistry works at extremely low temperatures. They breathe hydrogen instead of oxygen and use it to burn acetylene instead of glucose, exhaling methane instead of carbon dioxide. The low temperature and inefficiency of this process renders the Glothr metabolism very slow, to the point where they move, think, and act at rates considered glacial by most other species.
Glothr gain the energy and carbon they need by consuming acetylene. It is unclear if they ingest acetylene directly from the environment or from other organisms, but the novel's explanation of their biology implies the former; acetylene is contrasted with food rather than glucose.
Reproduction & Life Cycle Edit
Glothr have four sexes, and change between them throughout their lives. Their young are non-sapient, and while the Glothr care for them to some degree they do not consider their deaths, even in great numbers, to be a serious loss. Glother presumably have very long lifespans due to their slow biological processes.
Glothr rely primarily on an electrical sense, using it to navigate and to communicate. Despite their extremely dark environment, they can also see, and use bioluminescence as part of their language.
Glothr use similar technology to most Sh'daar races, flying faster-than-light spacecraft powered by vacuum energy. However, there are notable differences.
Normally, Sh'daar client races are not permitted to develop technology such as artificial intelligence and robotics, but the Sh'daar have exempted the Glothr from the robotics ban in order to allow them to better interact with faster-living species. The Glothr use plastic robots, some equipped with particle beam weapons, to communicate with species that they could not otherwise interact with.
The Glothr are also the only known wielders of "twister" technology, which allows them to speed up and slow down time. They use this to aid in communication, but twisters can also be used for offensive or defensive purposes. They can slow down kinetic attacks or weaken incoming lasers, or they can drastically amplify the power of a Glothr ship's laser weapons. This appears to violate the conservation of mass-energy, and it is unclear how the Glothr accomplish such a thing. Twister technology cannot be used as a time machine and does not allow travel to the past.
