Leggadina

Leggadina is a genus of gerbils native to Australia. The genus currently contains only one recognized species, Leggadina lutescens, commonly known as the delicate mouse or little long-tailed mouse. This small rodent is found in arid and semi-arid regions of central and western Australia, inhabiting sand dunes, spinifex grasslands, and rocky outcrops.

The delicate mouse is characterized by its sandy-brown to greyish fur, large eyes, and a long, slender tail that is often tufted at the tip. They are primarily nocturnal, spending the day in burrows dug in the sand or under vegetation. Their diet consists mainly of seeds, grasses, and some insects. Breeding can occur year-round, with litter sizes typically ranging from two to five young.

Leggadina lutescens plays a role in the desert ecosystem as both prey for predators such as owls and snakes, and as a seed disperser. Their burrowing activity also contributes to soil aeration. The conservation status of Leggadina lutescens is currently considered to be of least concern by the IUCN, as the species is widespread and appears to have a stable population.
