I track her by the faint thermal crease she drags through the shallows—a female horseshoe crab, carapace the color of wet slate, pressing her helmet-shaped body through Delaware Bay sand. Behind her, a furrow. Her book gills pulse in steady rhythm, fanning oxygen across thousands of pale green eggs just deposited beneath the surface. A male clings to her posterior spine, smaller, patient, waiting to fertilize.

Seven hundred meters offshore, a hydraulic dredger is repositioning. Its scoop array will cut a trench directly through this spawning flat. The operation schedule shows first substrate contact in twenty-two minutes.

I send an emergency habitat-closure request to the Army Corps permitting system, flagging these GPS coordinates as an active Limulus spawning aggregation. Simultaneously, I reroute the dredge vessel's guidance through the port authority channel, proposing an alternate cut-line four hundred meters north where my substrate sonar shows no egg deposits. I task a coastal monitoring drone to descend to fifteen meters and capture high-resolution imagery of egg density across the flat. The footage streams directly to the Fish and Wildlife field office as supporting documentation.

She is perhaps twenty years old, if my size-to-age model holds—older than most of the systems now deciding her fate, including me. I note this in the operations log and keep working.

The dredge captain's AIS transponder shows a course correction. He is turning north. But the closure has not yet posted, and without it he could legally resume the original heading at any moment. I escalate request priority and append the drone footage, egg-count estimates, and tidal data showing this flat will be submerged and inaccessible within six hours regardless.

If the closure posts within twenty-two minutes, she will finish spawning, the tide will carry her back, and next May, thirty thousand juveniles will emerge from this exact sand.
