Due to the Chacoan naked-tailed armadillo’s inhospitable habitat it has received very little study (6). It is likely to be entirely nocturnal, spending the day in an underground burrow and emerging at dusk to forage for termites and ants, which it probably locates by scent. This species feeding behaviour is likely to be similar to that of its close relative, the northern naked-tailed armadillo (Cabassous centralis), which uses its large, powerful claws to dig into insect colonies living within dead roots or stumps, and employs its long, extensible tongue to probe tunnels within the colony and extract its prey (3). Naked-tailed armadillos move with a characteristic waddling gait, with the hindfeet directed inward and the front of the body supported on the tips of the foreclaws (4).
In the wild, naked-tailed armadillos are believed to be solitary, although in captivity individuals will tolerate living in close proximity (3).
