 The female typically has fifteen teats, although the exact number can vary; four are on the chest, and the remainder, including a single median teat, on the abdomen.The Brazilian gracile opossum is found only in Brazil, being endemic to the south-eastern parts of the country, from Espirito Santo to Rio Grande do Sul.It inhabits rainforests and partly deciduous forests scattered in the southern regions of the cerrado ecoregion, but, being able to forage successfully on the ground, is less affected by fragmentation of forest habitats than more purely arboreal animals.
