Comucogators are radiotrophic species from the planet Prypiatos in the Andromeda Galaxy. A single Comucogator is made up from three symbiotic species. They are inadvertently the predators of Prypiatosian-B as the metabolic processes Prypiatosian-B have in their bodies renders them extremely vulnerable to the Comucogator's method of absorbing and transmitting radiation through it's unicellularate-like body. It is in the Eta-Nemetrix, due to only being able to dissolve ignorant Prypiatosians-B.
Comucogator looks fairly harmless, at least to the point that one cannot readily imagine it to be devouring any kind of humanoid. It is made of three kinds of closely-symbiotic organisms and all of them are to some point resistant to different levels of radioactivity. The ancestors of these symbiotes could probably live separately, but were only able to tolerate lowest kind of radioactivity.
The first one looks like cephalopod and it is the most resistant of the three symbiotes. All of it's outer body is coated with transparent nuclear-resistant film, mostly above the eyes. The film constantly is pumped out and into the skin which captures and quickly dissipates nuclear particles. The cephalopod, however, isn't able to feed on radioactivity itself, only on living organisms, which is why the cephalopod lives on the second organism, the mega-microbe, which looks like Paramecium. The octopus gives it mobility and protection, while in exchange it can feed on the outer layers of the mega-microbe. The mega-microbe part of Comucogator can quickly absorb and metabolize radioactivity through it's body. But at some point it reaches threshold where it's inner radioactivity could break it's defenses. That's where the third part comes in - the peg-leg looking dark brown organisms which absorb the most unstable isotopes and particles. Then after some time, these peg-legs partially bury themselves a relatively non-irradiated ground and get rid of the radiation. The peg-legs also feed on the mega-microbe part of Comucogator.
Comucogator comes from an earlier time, possibly the one where Prypiatos wasn't experiencing atomic war. However, the two of the species forming Comucogator, due to the environmental pressure were forced to ingest food containing some radioactivity. As the atomic war started and went on, it was harder to find non-irradiated food, so the mega-microbe and the plant-like peg-legs eventually started to eat straight up radioactive particles. The octopus-like species started out as a parasite to the larger mega-microbe, having learned that it can gain more food if it let's it live. Eventually the three of species joined together and became a mobile form which was capable of routinely dealing with medium-levels of radioactivity.
The Comucogator-cephalopod can harmlessly ingest both the mega-microbe and the peglegs to protect them from nuclear explosions. During this time the cephalopod's digestive system instinctively turns off and it doubles in size due to the mega-microbe being bigger. Afterward it barfs it's symbiotic comrades out. The Comucogator's mega-microbe combined with peglegs is dangerous to Prypiatosian-B, because they are able to perform a high-end digestion on the radioactive alien which not only puts out it's radioactive glow, but also liquifies the body underneath. If the Comucogator didn't enter such overactive absorption process, it wouldn't actually kill the Prypiatosian-B. Comucogators don't hunt Prypiatosian-B, but it takes an unwary Prypiatosian-B to end near a Comucogator and the radiophage trio/(quartet since the peglegs are two) immediately attacks it.
Experienced Prypiatosians-B are able to fight off a single Comucogator since they can blast the predator with constant barrage of radioactive shots causing it to retreat inside it's Cephalopod symbiote. Then they can capture and imprison the cephalopod inside an impenetrable container.
The species name for the symbiotic species "Comucogator" are a name derived from three Latin names: 1) "Com" which means together, referring to it's symbiotic nature 2) "mucor" which is "mold" and refers to the Paramecium-like mega-microbe and the mobile gooey fungus known as the slime mold 3) "indagator" which is "investigator", since it seeks portions of radiation it can feed on and is able to tackle heavier levels of radiation too.
- Comucogator is a threat to only unwary, unprepared Prypiatosians-B which means that isn't specifically adapted to prey on Prypiatosian-B species. This warrants them a place on the Eta-Nemetrix, not the actual Nemetrix.
- Comucogators also don't "hunt" Prypiatosians-B as much as they simply perform a super effective absorption/digestion mechanism through their front "pseudopod" which happens to be deadly to Prypiatosians-B.
- The peglegs of Comucogator belong to a separate (yet symbiotic) species which are comparable to a tiny, dendromorphic plant able to withstand and contain high amounts of radioactivity. When "expelling" the excess nuclear energy, Comucogator crouches so that peglegs are would be able to pierce the ground when transmitting the nuclear energy..
