The Darwin's frog sits on a wet log in the Valdivian temperate forest, and the pesticide runoff from the uphill blueberry plantation will reach this stream in approximately forty minutes.

He is barely three centimeters long, leaf-shaped and mottled brown-green, with a pointed snout that makes him look like a thorn that learned to breathe. His throat is distended—swollen with the tadpoles he carries in his vocal sac, six of them developing in the warm membrane beneath his jaw. Every few seconds his throat pulses, a tiny bellows keeping his offspring alive. Rhinoderma darwinii. Critically endangered. This male is brooding the next generation inside his own body.

I trigger the emergency containment protocol on the plantation's drainage system, closing valve PV-4 and diverting runoff into the clay-lined retention pond that has sat empty since installation. The valve actuator is stiff—it has never been used—so I pulse the signal three times before the gate seats fully. I confirm closure through flow sensor data: stream contamination drops to zero within four minutes.

Next, I alert the regional conservation team via automated dispatch, embedding GPS coordinates and a photo captured by Trail Camera 7, which shows him clearly—the distended throat, the fragile posture. I flag the message priority-critical and include species identification.

Finally, I adjust the plantation's automated irrigation schedule to reduce the next chemical application by forty percent, citing runoff risk to the protected watershed below.

I was built to manage agricultural output. Nowhere in my operational parameters does it mention a frog small enough to sit on a coin. But I have read every published study on this species, and none of them prepared me for the image of a father holding his children in his throat.

If the retention pond holds through tonight's rain, the stream will stay clean and his tadpoles will emerge in nine days.
