A tiny Australian marsupial that looks mouse-like at first glance but lives like a miniature predator. It has a slim body, a pointed snout, bright, watchful eyes, and relatively large ears that seem to be constantly listening for faint movement. Its fur is usually a soft gray-brown on top with paler underparts, a practical color scheme that blends into dry grass, sandy soil, and leaf litter. As the name suggests, its tail is notably long and thin—more like a delicate balancing line than a chunky storage tail—giving it a sleek outline when it runs.

Dunnarts are often confused with rodents, but unlike mice, they’re insect-eaters first and foremost, and they hunt rather than graze. The slender-tailed dunnart is especially built for darting through open patches between clumps of grass and low shrubs, where it can pounce on prey and then vanish back into cover. Compared with dunnart species that store noticeable fat at the base of the tail, the slender-tailed dunnart typically keeps a slimmer tail profile, giving it a more streamlined look.

Its daily routine is mostly nocturnal, meaning the slender-tailed dunnart does most of its hunting after sunset when the ground cools, and shadows offer protection. It searches for insects and other small prey using smell and hearing, often moving in a pattern that looks like a tiny search-and-rescue team: a quick dash, a sudden stop, a head tilt, then another burst. It may pounce with surprising precision, grabbing prey with sharp teeth and strong jaws for its size. During daylight, it usually rests in a sheltered nest—sometimes in a shallow burrow, under a log, inside a grass clump, or tucked into dense vegetation—places that help it avoid heat, reduce water loss, and stay hidden from predators.
