Chudeau's spiny mouse has stiff, spine-like hairs over the rear part of its back. It is most often recorded in rocky places and is mainly active at night.
The back is gray with orange tones and the flanks are paler, while the belly is white. The spine-like hairs cover a larger area of the back in older individuals.
It is terrestrial and mainly nocturnal. It may spend the day in rock crevices, and its wild diet is thought to include insects.
It is often trapped in rocky places, but it has also been recorded in gardens, palm groves, food stores, and houses.
