The Pilbara-Ningaui ( Ningaui timealeyi ) is a very small member of the predator family . It is found in Western Australia in the west of the Pilbara region , in the north of the Gascoyne region and in the north of the Little Sand Desert .
features
The Pilbara Ningaui reaches a head-torso length of 56 to 76 millimeters (males) or 56 to 65 millimeters (females), a tail length of 63 to 95 millimeters (males) or 57 to 68 millimeters (females) and a Weight from 3.6 to 9.5 grams (males) or 3.5 to 7.5 grams (females). In contrast to the flat-head pouch mice ( Planigale ), the top of the head is rounded and covered with relatively long hair. The fur of the Pilbara-Ningaui is monochrome gray while that of the southern Wongai-Ningaui ( Ningaui ridei ) is reddish-brown. The pads of the Pilbara-Ningaui are less than 1 mm long, those of the Wongai-Ningaui are longer than 1 mm.
Habitat and way of life
The Pilbara-Ningaui lives in deserts and sandy coastal landscapes overgrown with prickly head grasses , low bushes and trees (especially Acacia xiphophylla ), mostly near permanent or periodic watercourses. It is nocturnal and feeds on invertebrates, especially cockroaches and centipedes . Captive specimens also ate grasshoppers , crickets, and small skinks , but scorned beetles and millipedes . Females with pups in their pouches were caught between September and March, when most of the rain falls. The four to six young animals are arranged in a ring in the bag. They become self-sufficient weighing 2 grams and were caught in traps from December to May. In March the population consists mostly of independent young animals. Some adults can still experience a second breeding season. Males are aggressive towards one another during the breeding season and females carrying young animals in their pouches avoid contact with conspecifics during this time.
Danger
The IUCN classifies the Pilbara-Ningaui as Least Concern . It is the most common small mammal in the Pilbara region and is also found in two protected areas, Karijini National Park and Millstream Chichester National Park . In dry years, the population is likely to decline sharply and the survivors then colonize the whole region again from wetter areas.
