The Guahiba slim-pouch rat ( Cryptonanus guahybae ) is a species of marsupial that occurs in a small area near the cities of Porto Alegre and Guaíba in southern Brazil in the state of Rio Grande do Sul .
description
The animals reach a head trunk length of 7 to 10.2 cm, have a 9.6 to 13.5 cm long tail and reach a weight of 14 to 25 g. The tail is about 20% longer than the head and torso combined. The fur on the back and the top of the head are red-brown, the head a little lighter than the back. Narrow, dark circles around the eyes extend forward to the nose, but do not reach the base of the relatively small ears. They can also be absent. The underside of the body is light gray, the chin is whitish. The fur is long. The top of the tail is slightly darker than the underside. The females have 15 teats, one in the middle and seven on each side, but no pouch.
Habitat and way of life
The Guahiba slim-pouch rat occurs in a small area of the Brazilian pampas , in the restinga , a coastal forest biotope and in riverbank forests with sandy soils. Since most of the specimens that have been caught so far fell into traps that stood on the ground, it is assumed that the species mainly lives terrestrially. However, some individuals have also been caught in traps placed in the vegetation at heights of 0.5 to 1.5 m. So far nothing is known about the nutrition of the animals and their reproductive behavior.
The IUCN can not provide any information about the population and the degree of endangerment of the Chaco slim-pouch rat . So far only a few specimens have been caught and the limits of the distribution area are so far unclear.
