Common Diarroebas

The Common Diarroebas are the progeny of the venerable Diarrhea Cell - one of the few immediate splits of the 2s2tworld LCUA that never went beyond a unicellular grade, in this case as an amoeboid predator of other microbes; then again, it did not need to diversify further than that. Even as this stock speciated into the Common Diarroebas we see today, they are overall much like their old ancestry.

Common Diarroebas can be found all throughout 2s2tworld provided there is enough wetness, with a total species diversity numbering in many hundreds. The typical Common Diarroeba species is a substrate-dwelling predator, slinking between mineral grains and sending its pseudopods towards any organic matter it can sense. As the ancestral Common Diarroeba was a substrate-dwelling microbe itself, much of the genus group is quite tolerant of low-oxygen conditions, and a few specialized species can even be found where oxygen is extremely scarce, if not in as much abundance as their more oxygenated cousins.

While most species of Common Diarroeba are substrate-dwellers, there exist many species assuming a variety of other niches and specializations. Some species thrive best instead in the water column, gorging on banquets of algae, marine snow, and smaller faunal microbes. Freshwater species bear enlarged vacuoles to maintain osmotic equilibrium, and species where water is limited can perform momentary cryptobiosis until conditions become more favorable. As spite-bearing prey like bruhs may be found in their environments, many diarroebas possess specialized lysosome-like vesicles which break down the compound in time. These unicellular organisms occupy a great range in size, with species in the larger rungs being just visible enough to the naked eye to appear as a pale-brown speck.

As mentioned before, even with such diversity the Common Diarroebas still retain their ancestral traits, and are often indistinguishable from the Diarrhea Cell. Typical of an amoeboid cell, a diarroeba’s cytoskeleton is quite pliable, able to form and reabsorb copious pseudopods, and distort its own shape with ease. There however lies one major difference between the Diarrhea Cell and a diarroeba: a species of Common Diarroeba is polynucleate, and can exchange nuclei with receptive conspecifics. While, given the resources, just as content to fission off genetically identical copies, diarroebas will more readily perform this recombination of genetic material as to ensure healthier populations, and is in fact the main driver behind the diversity of the Common Diarroeba genus. Linking pseudopods with a receptive partner, nuclei containing redundant genes are swapped out, and now as both partners each carry distinct mixtures of genetic material, promptly fission off daughter cells, each with sufficient shares of their parents’ genetics. Sometimes nuclei can be shared between members of different diarroeba species, further blurring genetic boundaries.

It is worth noting that, as the cousin Radio-Feeding Diarrhea has acclimated better for the unique conditions of HRI, the Common Diarroebas have been unable to establish notable populations to any success there, and are therefore extremely rare.

Because the earliest Common Diarroebas are identical to the original Diarrhea Cell in niche and they are able to exchange genetic material, they have replaced their ancestry.
