Dirtswimmer Radiogrub

As the increasing intensity of radiation melts more and more of the rectangle land’s frost, more of its environments open up to be occupied by its inhabitants. In the case of the Dirtswimmer Radiogrub, the soil has now become warm enough year-round to facilitate active burrowers. With soil warm enough for consistent burrowing, more of its nutrients become available for cohabitant radioboita, and with their activity, their warming influence - and thus their range - expands, breaking up more and more of the land’s soil. This would reach a point in which the Dirtswimmer Radiogrub has become a crucial component in maintaining soils throughout its range.

To facilitate subterrene locomotion, the Dirtswimmer Radiogrub has become substantially smaller, yet more elongate, making for easy navigation through burrows. Its frontmost parapodia terminate in spade-like plumbochitin claws, plowing through dirt in alternating motions. Its other five pairs of parapodia are more evenly spaced to aid in this, pushing dirt trailing behind and not getting in the way of the front parapodia. Its plumbochitin plates have flattened and multiplied into a scaly coat as to minimize obstruction. Similar to the related Radiomite, the Dirtswimmer Radiogrub’s nutrient intake surface has become centralized around its frontmost palps, as it is no longer efficient for it to diffuse food from its entire form. These palps are dense with digestive surfaces, and break down whatever organic matter they grab a hold of to be processed. To further enhance food intake, a fourth palp has developed. This has the consequence of making the dirtswimmer a slightly more efficient scavenger - still not enough to pose a major competitive threat though. These tendrils also possess some chemoreceptive function.

The Dirtswimmer Radiogrub is most common in wetter soils as the water it takes in is essential to fuel its fusiotrophic reactions. Whatever predators that can withstand its radioactive emissions will likely fall to its high spite content.

Like their ancestry, larval Dirtswimmer Radiogrubs bud off their parent’s rear end, resembling miniature versions of the adults.
