Least groove-toothed swamp rat

The least groove-toothed swamp rat (Pelomys minor) is a rodent of the family Muridae, the large family of Old World rats and mice, placed in the genus Pelomys. It is found in four countries of central and southern Africa: Angola, the Democratic Republic of the Congo, Tanzania and Zambia. Its natural habitat is moist savanna, the wetter kind of tropical grassland with scattered trees. Its English name places it among the groove-toothed swamp rats. The Wikipedia article on it is short, so beyond its classification, its four-country range and its savanna habitat little else is documented here, and no population figure, threat or conservation status is stated in that article.
