Habitat and Ecology [top]

Habitat and Ecology: It is a paramo stream-living species which is probably primarily a predator on aquatic macroinvertebrates, supplemented with fish. This mouse occurs close to small, clear, cold, and fast flowing stream, downstream from a small (2.5 m) waterfall. The water is no more than 40 cm deep at any point and appeared extremely well-oxygened. The examination of the stomach contents showed the remains of fish (scales, bones with attached flesh), along with larvae of aquatic insects (including Ephemeroptera and Trichoptera) (Barnett, 1997).
