The desert narrow-foot pouch mouse ( Sminthopsis youngsoni ) is a species of marsupial mammal from the genus of the narrow-foot pouch mice , which occurs in the interior of Australia and in large areas of northern Western Australia, including in coastal dunes.
description
The head body length of this species is 66 to 71 mm, plus a 62 to 68 mm long tail. The weight varies between 8.5 and 12 g. It is therefore smaller than the Great Hair-footed Narrow-Footed Pouch Mouse ( Sminthopsis hirtipes ), which occurs south of its range, and also has a shorter tail, shorter ears and smaller hind feet in relation to body size. Both species differ from other narrow-footed pouch mice in their broad feet, grainy soles, and silvery hairs on the soles of their feet. These hairs are shorter in the desert narrow-foot pouch mouse and are less dense than in the large hair-footed narrow-foot pouch mouse. The section of the tail of the desert narrow-footed pouch mouse close to the body is usually slightly swollen. The back fur is brownish yellow, the belly side whitish.
distribution and habitat
The desert narrow-foot pouch mouse occurs in the red-colored deserts of inner Australia, in sand dunes and in open bushland. Their habitat is made up of acacias , grevillings , myrtle heaths and tyrolean , as well as island-like stocks of casuarina , eucalyptus , owenia and prickly head grasses . It is nocturnal and spends the day underground in caves, often in those dug by agamas or spiders. Nothing more is known about the diet of the species. Desert narrow-footed bag mice get their young mainly in spring, just before the invertebrate population increases dramatically in the warm months. Females with juveniles in their pouches, a maximum of six, were mainly caught between September and January. Males with swollen scrotum were mainly caught in August and September.
status
The IUCN estimates the population of the desert narrow-foot pouch mouse because of the large distribution area, the frequency of the animals and because of the occurrence in several protected areas (including Karlamilyi National Park and Uluṟu-Kata-Tjuṯa National Park ) as Least Concern.
