The long-tailed sleeping bag ( Cercartetus caudatus ), also called the New Guinea sleeping bag , is a small mammal that lives in New Guinea in the Maoke and Bismarck Mountains , in the north of the Vogelkop Peninsula , on the Huon Peninsula and on the Cape York Peninsula between Cooktown and Townsville in Northeast Australia.
features
The small marsupials reach a head body length between 10 and 11 cm and have a 12.8 to 15 cm long prehensile tail. In most cases, the tail is at least 14 cm long. They weigh 25 to 40 g. Their fur is brown-gray to red-brown on the back and light-gray to whitish on the belly. The hair around the big eyes is black. The mouse-like ears are also relatively large. The third premolar of the upper jaw is smaller than the molars and is not notched or sawed. The females' well-developed pouch opens backwards.
habitat
The long-tailed sleeper lives in New Guinea in primary and secondary forests at altitudes of 1500 to 3450 meters above sea level. In the coastal plain of northwest Queensland, the species occurs in forests characterized by eucalyptus ( Eucalyptus ) and myrtle heaths ( Melaleuca ), at altitudes of more than 300 meters in rainforests.
Way of life
The animals are nocturnal and sleep alone or in small groups in nests during the day. B. build on screw trees , in tree hollows or in tall grass or ferns. The nests are built from leaves and usually have a diameter of about 15 cm. If the temperature drops to 7 to 9 ° C or less, it survives the time in the torpor . During their activity time at night, long-tailed sleeper oysters are very active and can make horizontal jumps of more than a meter in width. They feed on arthropods, including spiders, crickets , beetles, moths, and cockroaches , and possibly also flower nectar, pollen, and plant saps. The small marsupials probably reproduce twice a year, from January to February and from August to November. The females get one to four young animals, which leave the bag after 45 days when they weigh 5 to 7 g. They become completely independent 80 to 92 days after their birth, weighing 10 to 15 g. The predators of the long-tailed sleeping baggy include pouch martens ( Dasyurus ), domestic cats, owls and pythons .
The long-tailed sleeping bag is considered safe.
