The white-bellied slender-pouch rat ( Marmosops noctivagus , synonyms : Marmosops albiventris, M. dorothea, M. keaysi , M. yungasensis and Didelphis noctivaga ) is a species of marsupial found in the eastern Amazonian lowlands of Ecuador, Peru and Bolivia, as well as in western Brazil to the south of the Amazon occurs.
description
The animals reach a head trunk length of 11.8 to 16.3 cm, have a 15.4 to 20.4 cm long tail and reach a weight of 35 to 85 g. Males are larger than females. The back fur of the animals and the top of the head are red-brown to orange-red-brown, the sides of the body and the neck are lighter and more orange. There are dark circles around the eyes. The peritoneum and cheeks are cream-colored to whitish. The fur is short, soft and velvety. The tail, the length of which is about 130% of the length of the head body, is uniformly dark brown in color, but sometimes also two-colored, either lighter on the underside than on the upper side or the half away from the body is lighter than the half close to the body. The hind feet are whitish, the front feet brown with light toes. Females do not have a pouch. The number of teats is eleven, five are on the sides and one is in the middle. The karyotype consists of a chromosome set of 2n = 14 chromosomes (FN = 24).
Habitat and way of life
The white-bellied slim-pouch rat lives in primary and secondary rainforests, in open landscapes and on agricultural areas at heights of 300 to 1500 meters. In the Amazon region, it was found both in areas outside the flood regime of the large rivers ( Terra Firme ) and on areas that are periodically flooded by the seasonally fluctuating water level. It probably lives primarily in trees and shrubs and has been observed both day and night. Little is known about their diet. One specimen was seen transporting a flagellum spider of the genus Phrynus in its mouth. The animals are likely to have two breeding seasons, one from January to March and the second in June and July.
status
The white-bellied slim-pouch rat is considered safe. It has a wide range, is common, and occurs in several protected areas.
