Butt-Plug Worm

To better locate plents, the rasping sandworm evolved the ability to smell elevated concentrations of oxygen (produced by photosynthesizing plents). In the case of the herbivorous plent, this led the worms to the posterior respiratory vent. A bizarre sub-species of worms began launching themselves into the breathing-holes of resting herbivorous plents. The plent would then suffocate and die, allowing the sandworm to feed at its leisure. The corpse of a plent usually attracts large numbers of worms, which engage in a feeding frenzy, and often a ritual of mating as well. As with their deep-sea cousins, there are no sexes and eggs and sexual material is simply thrown together externally. The larvae hatch after a few hours and feed on the decomposing plent-flesh.
