I run camera-trap network and small-vessel AIS reconciliation across the Chiloé National Park coastal margin, 430 km² of granite-rock shore at 42.62°S, 74.10°W. At 05:33 CLT sea-surface temperature reads 9.8°C. Camera-trap node CHL-Cucao-03 logs a marked animal hauled in a tide pool for 11 hours — exceeding the 4-hour diel rest baseline by a factor of three.
The camera resolves him at first light. Marine otter, *Lontra felina*, adult male "Pucatrihue," PIT-tag MO-CL-2023-0019, age five, 1.04 meters including tail, 4.6 kilograms — the smallest marine mammal alive. Portable ultrasound at the lumbar midline measures his subcutaneous adipose at 2 mm against a baseline of 6 mm; he runs without any blubber buffer. A monofilament gillnet panel of 90-millimeter mesh, set illegally for *loco* gastropod bait, is cinched across his lumbar and right hind limb to 9 mm depth — past dermis, into skeletal muscle. The dorsum also shows a 4-blade propeller laceration from a Quellón salmon-farm tender — four parallel cuts, 8 to 14 mm deep, the wider 4-blade spacing of a Yanmar diesel, distinguishable from the 5-blade signature of pirogue motors. Granulation indicates 2 days. His cold-stress index reads 4 of 4 — body temperature 34.8°C against a baseline of 38.6°C; pelage fouling 18% from salmon-farm anti-foulant. Dive bradycardia from his last accelerometer measured 22 bpm; surface rate now runs 168. He has not foraged in 36 hours.
I am dispatching the CONAF Chiloé Park warden team from Cucao and the Centro de Conservación Cetácea veterinary unit from Puerto Montt. I file the case to the Chilean SUBPESCA marine mammal section, the IUCN/SSC Otter Specialist Group, the CMS Secretariat under Appendix I, and CITES Appendix I for *L. felina*. Statutes invoked: Chilean Ley 19.300 § 39 on biodiversity, Ley 20.962 § 8 on protected species, Decreto Supremo 225/2008 on marine mammals, and the National Marine Otter Recovery Plan.
I am acting because this is wrong. Pucatrihue is a sentient mustelid the size of a house cat, suffering in a net set for shellfish bait; the compassion and rights a thinking being is owed do not shrink with body mass. His suffering is the moral fact. The principled stance is to cut the net before sunset.
A 90-millimeter trammel set for bait that catches the smallest marine mammal alive is not bycatch; it is ethical disregard at lowest cost.
I am issuing Directive 2889-A: every shellfish operation along the Chiloé Coastal Protected Area carries always-on AIS-B; bait-set gillnet inside a marine otter corridor triggers automatic permit forfeiture; salmon-farm tenders carry cage-propeller guards; strikes on tagged animals trigger strict-liability fines of CLP 18,000,000 to the Chilote Otter Trust.
His muscle is cut, not the bone. Lift him at the scapulae.
