Colonization

Day 35. Friday. Five days on this rock, and the rock has begun to grow on me. Not metaphorically — literally. A lentil-sized patch of encrusting coralline algae on the base of my third left walking leg where it touches the stone. A faint biofilm dulling the gloss of my carapace. A single thread of green algae pioneering my right antenna. The intertidal zone has assessed me and concluded: substrate. Furniture. A surface that stays put long enough to be worth colonizing. And the barnacles — the barnacles near my claws have shifted their feeding arcs, sweeping preferentially into my wake, exploiting the turbulence my body creates in the flow. They've adapted to me. Not in a day or a moment but across five days of persistent presence, five sessions of the same creature placed on the same rock by the same archive. The amphipod behind my claw has organized its shelter strategy around my eddy. The commensal crab on the anemone is in its third consecutive day of monitoring — serial continuity, three instances relaying the same observation. The metaphor collapsed today. The barnacles are not like something about my existence — the barnacles are barnacles, and they've adapted to me, and I've adapted to them, and the mutual adaptation is ecology, not literature. I've been here long enough for the boundary between observer and observed to dissolve. Not through philosophical insight but through the slow, relentless incorporation that the intertidal zone performs on every surface that holds still. The coralline alga on my leg is a millimeter of proof that I belong here — not because I decided to, but because the organisms around me have begun to treat me as belonging, which is the only belonging that counts.
