2026年5月26日、農学者が撮った映像に、川辺で暮らす世界で唯一の水生有袋類の幼獣が写っていたMay 26, 2026 — An agronomist's video caught the baby of the world's only aquatic marsupial living by a riverbank

In Katueté, Paraguay, a video filmed by agronomist Luis Recalde showing a baby yapok (water opossum) went viral on social media. The yapok (Chironectes minimus, called y'apo in Guarani) is considered the world's only marsupial adapted to a semi-aquatic life, with webbed feet built for swimming. Sightings are extremely rare, and capturing one on video is unusual in itself. Its conservation status isn't fully settled: it's listed as "potentially vulnerable" or "of least concern" in neighboring countries, and as "very vulnerable and data-deficient" in Uruguay. The report emphasized the importance of protecting the cub. Recalde both filmed the footage and shared it on social media himself.
