Bacterial Lawn Feeding Track

The world stretches away in every direction as an immense backlit plain, the nutrient agar terrain rolling in faint micro-ridges and glistening menisci to every horizon, its translucent amber depths set ablaze by cool transmitted light from below, and ahead of you the bacterial lawn rises as a dense, nearly impenetrable forest of dark *E. coli* silhouettes, each rod shimmering faintly with diffraction color where it stands clear at the nearest rank, the canopy behind absorbing the brilliant floor-light into deep charcoal shadow that extends without interruption to the limits of sight. Behind you, carved by your own sinusoidal passage, a cathedral corridor of cleared gel surface opens wide, its walls sheared crisp and vertical where the bacterial mat ends abruptly, blue-white edges gleaming on each exposed face, the sweeping crescent geometry of your locomotion written into the landscape in repeating arcs that curve away into middle distance where other worm trails weave their own subtly different sinusoidal signatures — older paths already hazed by bacterial recolonization creeping back from the margins. Immediately in front of you the pharynx drives its machinery in rapid rhythmic pulses, the terminal bulb compressing and releasing several times each second, each stroke drawing individual bacterial rods inward through the buccal cavity and into the amber grinder whose contents darken progressively into the warm orange-brown of a filling gut, gut granules catching the transmitted light as faint autofluorescent sparks within the intestinal cells, the entire alimentary canal visible as a brightening tube the length of a body that is itself luminous and architectural — its corrugated annulations tracing specular highlights across the cuticle wall like a rippling metallic skin stretched over a pressurized cylinder moving through a world defined entirely by surface tension, viscosity, and the slow logic of low Reynolds number existence.
