Hexborer

The hexborer split from its ancestor, the hexdriller. With the rise of the towering stiltbulb 'forests,' many organisms began adapting to take advantage of the new food source and habitat.

Some hexdrillers began to cluster around the micro-ecosystems that formed around the stiltbulbs, feasting on the detritus and decaying matter. Before long, they adapted to consume the stiltbulb's themselves.

Secreting an enzyme from their 'mouth' that would soften the root structure, the hexborers can weaken the roots enough that they can be tunneled into.

Their overall form has changed little, save for the evolution of sensory pits that can detect certain compounds, such as those found in stiltbulb roots. These are remarkably simple, consisting of little more than chemically sensitive cell clusters with thin protective films over them to prevent them from being harmed by soil and detritus.

They are located in between the corkscrew breathing tubes. Hexborers still incubate their larva in their central cavity for a time, but then 'regurgitate' them into piles of waste within their small burrows, rather than having them eat their way out of their body cavities. This way, they can reproduce multiple times in their lifetime.
