Ventricapillus solidis
Descended from a population of V. saccharovorum that were excreted from the digestive tract of W. dontria, after they started to break down the fecal matter after 10 hours of no new sugar they would begin to break down decaying organic matter closest to them. With time, they would specialize in breaking down organic material and become the first non-gut decomposers in the zone.
5μm long
originated in zone O
In order to get around, V. solidis has elongated its flagella to swim in the moisture found in the sediment. This adaptation makes it distinct in being one of the first descendants of V. saccharovorum that is fully terrestrial. To deal with the more variable conditions of a terrestrial lifestyle rather then in the gut of a host V. solidis developed the ability to slow down their metabolic functions and go into a period of little activity during periods where the weather is less favorable. Aside from these terrestrial adaptations V. solidis has convergently evolved similar adaptations as its cousin, V. jurvus, in zone C1. Much like its relative V. solidis relies on enzymes and its mild acid inherited from its ancestor to break down organic matter.
When it comes to reproduction, its pretty much the same as its relatives and ancestor; The species replicating a clone of itself by duplicating its genetic material and splitting the cell in half with the whole process taking about 30 minutes.
