The giant New Guinea nosebuilder ( Peroryctes broadbenti ) is a species of marsupial that occurs in southeastern New Guinea.
features
The giant New Guinea nasal purse reaches a head body length of 34 to 55.8 cm and has a 9.5 to 22.9 cm long tail. This makes the species the largest of all nasal aspers. It shows a clear gender dimorphism . The females weighed so far had a weight of 0.94 to 1.4 kg, while the males reached a weight of 2.9 to 4.9 kg. The hind foot of large specimens can reach a length of 10 cm, which is 20% longer than the hind feet of other large nasal sacs. The bristly back fur is dark reddish-brown in color. The fur becomes lighter towards the belly. Front and rear feet are light. The ears are relatively long. The scaly tail is slightly hairy on the upper side and covered with scaly tubercles on the underside. The premolars of the males are hypertrophic . The bag, which contains eight teats, opens to the rear.
Habitat and way of life
The animals live mainly in lowland rainforests, mostly near streams and rivers. In the north of the southeastern peninsula they occur at heights of up to 150 meters, in the southern foothills of the Owen Stanley Mountains they probably also live at heights of 500 to 1000 meters. The diet has not yet been studied in detail, but the giant New Guinea nasal aspirator is likely, like other nasal aspirators, to be omnivorous . So far, the contents of the stomach have only been examined once and plant remains were found. One female examined had two pups in the pouch. Nothing else is known about the reproductive behavior.
Danger
The IUCN lists the Giant New Guinea Noseband as “endangered” because of its declining population for many years. Most of the scientifically studied specimens were caught in the 1950s. Giant New Guinea nosebags are hunted for bushmeat and hunted specimens appear from time to time even in the markets of Port Moresby . In addition, living space is being lost due to the expansion of agricultural land. Although there are protected areas in the distribution area of the giant New Guinea nasal purebred, the species has not yet been detected there.
