Gray brush-furred rat

The gray brush-furred rat, Lophuromys aquilus, is a species of rodent in the family Muridae, the large family that holds most of the world's rats and mice. It is found only in the Democratic Republic of the Congo, so its whole known range lies inside one country. Its natural habitats are subtropical or tropical swamps, subtropical or tropical moist montane forests, and subtropical or tropical high-altitude grassland, which means it lives across wetland, mountain forest and upland grass rather than in a single kind of country. It is threatened by habitat loss. The Wikipedia article that describes it is a short stub and gives no figures for body size, lifespan or population.
