Biology and behaviour

The target rat is largely nocturnal and feeds on the ground on green vegetable material and fallen fruit, supplementing these with some insects. In addition to moving along the ground, it often climbs into the rainforest understory, although not high into trees. It has been reported to construct spherical nests of shredded grass.
