Anderson's pygmy pouch rat ( Marmosa andersoni ) is a species of mammal belonging to the genus of pygmy pouch rats , which is only known from three small areas near the Peruvian city of Cusco , Camisea and the Manú National Park . The species was named in honor of the US zoologist and museum curator Sydney Anderson .
features
The animals reach a head body length of about 12.5 cm, and have a 17.5 to 19.3 cm long tail. Their weight is between 28 and 38 g. The back fur of Anderson's pygmy pouch rat is reddish-brown, the hair has brown tips. A zone in the middle of the back is yellow-brown, there is no dark central strip of the back. The black eyes are surrounded by black circles under the eyes, which extend in front of the eyes with points to the muzzle but do not reach to the nose. The cheeks and throat are cream in color. The ears are gray-brown and translucent. The tail is only hairy for the first 20 mm near the body (proximal). It is darker on the top than on the bottom. The peritoneum is yellowish-brown to cream-colored. The females do not have a pouch. The number of teats is nine, one in the middle and four on each side. The fur in the teat region is white, soft and woolly. The rest of the fur is relatively long.
Way of life
Anderson's pygmy pouch rat occurs at all three known locations in lowland rainforests and undisturbed terra firme forests with only a few overhangs with a height of more than 30 meters. Four of the six most recently caught specimens were caught in bamboo thickets, one inside a bamboo of the genus Guadua . Little is known about the diet and reproduction of the opossum. Like other pygmy sac rats, they likely feed on insects and fruits. A female caught with pups had five pups with her. Four young animals were observed climbing in a bamboo thicket, probably in the immediate vicinity of the nest. All specimens observed or captured so far did not move higher than three meters above the ground.
Danger
The IUCN no longer provides any information about a possible risk to the animals, as insufficient data are available. As far as is known, Anderson's pygmy rat is not found in protected areas, but the Manú National Park is between two sites of the species.
