The Panama slim-pouch rat ( Marmosops invictus , Syn . : Marmosa invicta ) is a species of marsupial that occurs in the Central American Cordillera, which runs through Panama parallel to the coasts.
description
The animals reach a head body length of about 10.4 to 12.2 cm, have a 12.9 to 14.9 cm long tail. The weight of the animals has not yet been measured. The fur is relatively short with a hair length of 6 to 7 mm in the middle of the back. The color of the dorsal fur and the head is slate gray, dark gray-brown, blackish-gray or dark brown. The dark circles under the eyes only contrast slightly with the dark face. The cheeks are cream colored. A dark stripe in the middle of the back is missing. The peritoneum is slate gray, silvery gray to whitish. The belly hairs have dark gray bases and whitish tips. There is usually a whitish spot on the chin. The legs are dark, the top of the feet is covered with white hair, and there is a dark spot on the back of the hind feet. The tail, the length of which is about 125% of the length of the head body, is a uniform dark gray in most specimens. Only in some animals is the underside lighter. The Panama slim pouch rat has no pouch. The number of teats is seven, three each on the right and left and one in the middle.
Habitat and way of life
The Panama slender-pouch rat occurs in primary and secondary, heavily moss-covered and densely covered with epiphytes, wet forests and in submontane rainforests at altitudes of 450 to 1500 meters. It is probably nocturnal and lives both on the ground and climbing in shrubs up to heights of 1.5 meters. When the stomach contents were examined, remains of insects, fruits and the spores of arbuscular mycorrhizal fungi were found. Almost nothing is known about their further way of life and reproduction. In the east of its distribution area in the highlands of Darién it may occur sympatric with Marmosops caucae .
status
The Panama slim-pouch rat is considered harmless. It is also found in various protected areas (e.g. in the Darién National Park ) and apart from limited deforestation in parts of its range, there are no known threats to the existence of this species.
