Southern Naked-tailed Armadillo (Cabassous unicinctus) lives in tropical dry forest across Central and South America. Its conservation status is Least Concern.
Fascinating facts about the Southern Naked-tailed Armadillo
- The southern naked-tailed armadillo has a tail only about 16 cm long, a size shared by both males and females. Unlike most armadillos, the tail skin is covered with tiny scales rather than the larger scutes typical of the group. This reduced armour gives the tail a smoother appearance and, together with the hairless underside, sets it apart from its relatives.
- Females of this species are noticeably larger than males, reaching a head-body length of 38 cm and weighing about 3.8 kg, while males average 36 cm and 3.0 kg. Both sexes share the same tail length of roughly 16 cm, reinforcing the modest overall size of the animal.
- The armadillo's dorsal armour is divided into ten to thirteen mobile rings in the mid-section, providing a degree of flexibility that lets the animal bend its mid-body. This flexibility is used when it digs, as the creature initially rotates its body to create a rounded tunnel entrance before the passage flattens further in.
- When digging, the armadillo first rotates its body, producing a rounded tunnel entrance roughly 16 cm wide before the passage narrows and flattens about 45 cm in. It spends much of its time excavating these burrows, which serve as shelter and foraging bases. The tunnels are characteristically found within termite mounds, linking the animal's diet to its underground homes.
- Southern naked-tailed armadillos live alone, defending solitary territories throughout their range. In tropical zones they are described as nocturnal, yet observations further south show a shift to daytime activity. This flexibility in daily rhythm matches the species' broad habitat use from rainforests to open grasslands. Reproduction occurs year-round, allowing individuals to maintain their solitary lifestyle while continuously producing offspring.

About the Southern Naked-tailed Armadillo
In the warm, golden light of a South American evening, the Southern Naked-tailed Armadillo emerges, its armor-plated shell glistening like polished leather as it rooting through the underbrush with an air of quiet determination. With a curious, snout-led gait, it moves through the world, its long, pointed snout twitching as it uncovers hidden insects and sweet, buried treasures. As it digs and snuffles, its naked tail twitches back and forth, a metronomic counterpoint to the rustling of leaves and snapping of twigs that accompany its nocturnal wanderings.
