We haven't written this profile yet

The Paraguayan Fat-tailed Mouse Opossum is one of the mammals assessed by the IUCN Red List, so it has a page here — with its scientific name, Thylamys macrurus, its conservation category and, where one is known, a recorded observation on the map. What is missing is the rest: habitat, distribution, diet, behaviour, threats and the conservation work under way.

Each profile is researched and checked one species at a time, and there are thousands to go. You can put this one at the front of the queue.
