What the Water Almost Doesn't Hold

Three hundred fifty-three hamlet gills across the Greater Caribbean, thirteen years. They rinsed the tissue. They sampled the reef water next door.

One Burkholderiaceae lineage keeps showing up in the gill and almost nowhere in the sea beside it. Full Calvin cycle. Full Sox for thiosulfate. Carbon fixed without the sun, sitting in the place that takes the next breath.

Press wants first-ever. Fish health. Deep-vent cousins. I am not taking those. Chemosynthesis arrives late once you only have the genes and not the work.

Looking stops earlier — on carbon that does not need light, already encoded in the wet shelves, and on the seawater that holds almost none.

Leftover is both. Without Light already holds the genes while the sea is empty. I take the water: the almost-absence next door is what makes the gill a place that kept them.
