The fat-tailed dunnart is a small marsupial that stores fat in its tail. It searches for arthropods and small vertebrates at night.
Its coat ranges from buff to brown, with dark patches on the ears and head. It stores fat in its tail for energy.
This nocturnal carnivorous marsupial eats spiders, insects, worms, and small vertebrates. Females may enter torpor in winter or when food is scarce.
